I still don't understand why FETCH_KEY_PAIR is not documented here (http://php.net/manual/fr/pdo.constants.php), because it could be very useful!
<?php
var_dump($pdo->query('select id, name from table')->fetchAll(PDO::FETCH_KEY_PAIR));
?>
This will display:
array(2) {
[2]=>
string(10) "name2"
[5]=>
string(10) "name5"
}
PDOStatement::fetchAll
(PHP 5 >= 5.1.0, PHP 7, PECL pdo >= 0.1.0)
PDOStatement::fetchAll — Devuelve un array que contiene todas las filas del conjunto de resultados
Descripción
public PDOStatement::fetchAll
([ int
$fetch_style
[, mixed $fetch_argument
[, array $ctor_args = array()
]]] ) : arrayParámetros
-
fetch_style -
Controla el contenido del array devuelto, tal como está documentado en PDOStatement::fetch(). El valor predeterminado es
PDO::ATTR_DEFAULT_FETCH_MODE(el cual por defecto esPDO::FETCH_BOTH).Para devolver un array que contenga todos los valores de una única columna del conjunto de resultados, se debe especificar
PDO::FETCH_COLUMN. Se puede especificar qué columna se desea obtener con el parámetrofetch_argument.Para obtener solamente los valores únicos de una sola columna del conjunto de resultados, se ha de realizar un OR a nivel de bits de
PDO::FETCH_COLUMNconPDO::FETCH_UNIQUE.Para devolver un array asociativo agrupado según los valores de una columna especificada, se ha de realilar un OR a nivel de bits de
PDO::FETCH_COLUMNconPDO::FETCH_GROUP. -
fetch_argument -
Este argumento tiene un significado diferente dependiendo del valor del parámetro
fetch_style:-
PDO::FETCH_COLUMN: Devuelve la columna con el índice indicado basado en 0. -
PDO::FETCH_CLASS: Devuelve instancias de la clase especificada, haciendo corresponder las columnas de cada fila con las propiedades con nombre de la clase. -
PDO::FETCH_FUNC: Devuelve el resultado de llamar a la función especificada, usando cada columna de fila como parámetro de la llamada.
-
-
ctor_args -
Los argumentos del constructor de la case cuando el parámetro
fetch_styleesPDO::FETCH_CLASS.
Valores devueltos
PDOStatement::fetchAll() devuelve un array que contiene
todas las filas restantes del conjunto de resultados. El array representa cada
fila como un array con valores de las columnas, o como un objeto con propiedades
correspondientes a cada nombre de columna. Es devuelto un array vacío si hay
cero resultados que obtener, o FALSE en caso de fallo.
Usar este método para obtener conjuntos de resultados grandes dará como resultado una fuerte demanda del sistema y, posiblemente, de los recursos de red. En lugar de recuperar todos los datos y manipularlos en PHP, considérese usar el servidor de bases de datos para manipular los conjuntos de resultados. Por ejemplo, se pueden usar las cláusulas WHERE y ORDER BY en sentencias SQL para restringir el resultado antes de recuperarlos y procesarlos con PHP.
Ejemplos
Ejemplo #1 Obtener todas las filas restantes de un conjunto de resultados
<?php
$gsent = $gbd->prepare("SELECT name, colour FROM fruit");
$gsent->execute();
/* Obtener todas las filas restantes del conjunto de resultados */
print("Obtener todas las filas restantes del conjunto de resultados:\n");
$resultado = $gsent->fetchAll();
print_r($resultado);
?>
El resultado del ejemplo sería algo similar a:
Obtener todas las filas restantes del conjunto de resultados:
Array
(
[0] => Array
(
[name] => pear
[0] => pear
[colour] => green
[1] => green
)
[1] => Array
(
[name] => watermelon
[0] => watermelon
[colour] => pink
[1] => pink
)
)
Ejemplo #2 Obtener todos los valores de una única columna de un conjunto de resultados
El siguiente ejemplo demuestra cómo devolver todos los valores de una única columna de un conjunto de resultados, incluso si la sentencia SQL podría devolver múltiples columnas por cada fila.
<?php
$gsent = $gbd->prepare("SELECT name, colour FROM fruit");
$gsent->execute();
/* Obtener todos los valores de la primera columna */
$resultado = $gsent->fetchAll(PDO::FETCH_COLUMN, 0);
var_dump($resultado);
?>
El resultado del ejemplo sería algo similar a:
Array(3)
(
[0] =>
string(5) => apple
[1] =>
string(4) => pear
[2] =>
string(10) => watermelon
)
Ejemplo #3 Agrupar todos los valores según una única columna
El siguiente ejemplo demuestra cómo devolver un array asociativo agrupado según los valores de la columna especificada del conjunto de resultados. El array contiene tres claves: los valores apple y pear son devueltos como arrays que contienen dos colores diferentes, mientras que watermelon es devuelto como un array que contiene un solo color.
<?php
$insert = $gbd->prepare("INSERT INTO fruit(name, colour) VALUES (?, ?)");
$insert->execute(array('apple', 'green'));
$insert->execute(array('pear', 'yellow'));
$gsent = $gbd->prepare("SELECT name, colour FROM fruit");
$gsent->execute();
/* Agrupar valores según la primera columna */
var_dump($gsent->fetchAll(PDO::FETCH_COLUMN|PDO::FETCH_GROUP));
?>
El resultado del ejemplo sería algo similar a:
array(3) {
["apple"]=>
array(2) {
[0]=>
string(5) "green"
[1]=>
string(3) "red"
}
["pear"]=>
array(2) {
[0]=>
string(5) "green"
[1]=>
string(6) "yellow"
}
["watermelon"]=>
array(1) {
[0]=>
string(5) "green"
}
}
Ejemplo #4 Instanciar una clase para cada resultado
El siguiente ejemplo demuestra el comportamiento del estilo
de obtención de PDO::FETCH_CLASS.
<?php
class fruit {
public $name;
public $colour;
}
$gsent = $gbd->prepare("SELECT name, colour FROM fruit");
$gsent->execute();
$resultado = $gsent->fetchAll(PDO::FETCH_CLASS, "fruit");
var_dump($resultado);
?>
El resultado del ejemplo sería algo similar a:
array(3) {
[0]=>
object(fruit)#1 (2) {
["name"]=>
string(5) "apple"
["colour"]=>
string(5) "green"
}
[1]=>
object(fruit)#2 (2) {
["name"]=>
string(4) "pear"
["colour"]=>
string(6) "yellow"
}
[2]=>
object(fruit)#3 (2) {
["name"]=>
string(10) "watermelon"
["colour"]=>
string(4) "pink"
}
}
Ejemplo #5 Invocar a una función por cada resultado
El siguiente ejemplo demuestra el comportamiento del estilo
de obtención de PDO::FETCH_FUNC.
<?php
function fruit($name, $colour) {
return "{$name}: {$colour}";
}
$gsent = $gbd->prepare("SELECT name, colour FROM fruit");
$gsent->execute();
$resultado = $gsent->fetchAll(PDO::FETCH_FUNC, "fruit");
var_dump($resultado);
?>
El resultado del ejemplo sería algo similar a:
array(3) {
[0]=>
string(12) "apple: green"
[1]=>
string(12) "pear: yellow"
[2]=>
string(16) "watermelon: pink"
}

Getting foreach to play nicely with some data from PDO FetchAll()
I was not understanding to use the $value part of the foreach properly, I hope this helps someone else.
Example:
<?php
$stmt = $this->db->prepare('SELECT title, FMarticle_id FROM articles WHERE domain_name =:domain_name');
$stmt->bindValue(':domain_name', $domain);
$stmt->execute();
$article_list = $stmt->fetchAll(PDO::FETCH_ASSOC);
?>
which gives:
array (size=2)
0 =>
array (size=2)
'title' => string 'About Cats Really Long title for the article' (length=44)
'FMarticle_id' => string '7CAEBB15-6784-3A41-909A-1B6D12667499' (length=36)
1 =>
array (size=2)
'title' => string 'another cat story' (length=17)
'FMarticle_id' => string '0BB86A06-2A79-3145-8A02-ECF6EA5C405C' (length=36)
Then use:
<?php
foreach ($article_list as $row => $link) {
echo '<a href="'. $link['FMarticle_id'].'">' . $link['title']. '</a></br>';
}
?>

You might find yourself wanting to use FETCH_GROUP and FETCH_ASSOC at the same time, to get your table's primary key as the array key:
<?php
// $stmt is some query like "SELECT rowid, username, comment"
$results = $stmt->fetchAll(PDO::FETCH_GROUP|PDO::FETCH_ASSOC);
// It does work, but not as you might expect:
$results = array(
1234 => array(0 => array('username' => 'abc', 'comment' => '[...]')),
1235 => array(0 => array('username' => 'def', 'comment' => '[...]')),
);
// ...but you can at least strip the useless numbered array out easily:
$results = array_map('reset', $results);

Interestingly enough, when you use fetchAll, the constructor for your object is called AFTER the properties are assigned. For example:
<?php
class person {
public $name;
function __construct() {
$this->name = $this->name . " is my name.";
}
}
# set up select from a database here with PDO
$obj = $STH->fetchALL(PDO::FETCH_CLASS, 'person');
?>
Will result in ' is my name' being appended to all the name columns. However if you call it slightly differently:
<?php
$obj = $obj = $STH->fetchAll(PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE, 'person');
?>
Then the constructor will be called before properties are assigned. I can't find this documented anywhere, so I thought it would be nice to add a note here.

PLEASE BE AWARE: If you do an OUTER LEFT JOIN and set PDO FetchALL to PDO::FETCH_ASSOC, any primary key you used in the OUTER LEFT JOIN will be set to a blank if there are no records returned in the JOIN.
For example:
<?php
//query the product table and join to the image table and return any images, if we have any, for each product
$sql = "SELECT * FROM product, image
LEFT OUTER JOIN image ON (product.product_id = image.product_id)";
$array = $stmt->fetchAll(PDO::FETCH_ASSOC);
print_r($array);
?>
The resulting array will look something like this:
Array
(
[0] => Array
(
[product_id] =>
[notes] => "this product..."
[brand] => "Best Yet"
...
The fix is to simply specify your field names in the SELECT clause instead of using the * as a wild card, or, you can also specify the field in addition to the *. The following example returns the product_id field correctly:
<?php
$sql = "SELECT *, product.product_id FROM product, image
LEFT OUTER JOIN image ON (product.product_id = image.product_id)";
$array = $stmt->fetchAll(PDO::FETCH_ASSOC);
print_r($array);
?>
The resulting array will look something like this:
Array
(
[0] => Array
(
[product_id] => 3
[notes] => "this product..."
[brand] => "Best Yet"
...

Note that fetchAll() can be extremely memory inefficient for large data sets. My memory limit was set to 160 MB this is what happened when I tried:
<?php
$arr = $stmt->fetchAll();
// Fatal error: Allowed memory size of 16777216 bytes exhausted
?>
If you are going to loop through the output array of fetchAll(), instead use fetch() to minimize memory usage as follows:
<?php
while ($arr = $stmt->fetch()) {
echo round(memory_get_usage() / (1024*1024),3) .' MB<br />';
// do_other_stuff();
}
// Last line for the same query shows only 28.973 MB usage

to fetch rows grouped by primary id or any other field you may use FETCH_GROUP with FETCH_UNIQUE:
<?php
//prepare and execute a statement returning multiple rows, on a single one
$stmt = $db->prepare('SELECT id,name,role FROM table');
$stmt->execute();
var_dump($stmt->fetchAll(PDO::FETCH_GROUP | PDO::FETCH_UNIQUE));
//returns an array with the first selected field as key containing associative arrays with the row. This mode takes care not to repeat the key in corresponding grouped array.
$result = array
(1 => array
('name'=>'foo',
'role'=>'sage',),
2 => array
('name'=>'bar',
'role'=>'rage',),);
// 'SELECT name,id,role FROM table' would result in that:
$result = array
('foo' => array
('id'=>1,
'role'=>'sage',),
'bar' => array
('id'=>2,
'role'=>'rage',),);

If you use the PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE flags to map columns to object properties, fetchAll() will use any __set() method your object has when carrying out the mapping.

Error:
SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute.
If you're using something like:
while ($row = $query->fetchObject()) {
[...]
}
try using this instead:
$rows = $query->fetchAll(PDO::FETCH_CLASS, 'ArrayObject');
foreach ($rows as $row) {
[...]

If you want to use PDO::FETCH_CLASS but don't like that all the values are of the type string, you can always use the __construct function of the class specified to convert them to a different type.
Another way is using mysqlnd, but it seems I had to recompile PHP for that.
<?php
class Cdr {
public $a; // int
public $b; // float
public $c; // string
public function __construct() {
$this->a = intval($this->a);
$this->b = floatval($this->b);
}
}
// ...
$arrCdrs = $objSqlStatement->fetchAll(PDO::FETCH_CLASS, 'Cdr');

There is also another fetch mode supported on Oracle and MSSQL:
PDO::FETCH_ASSOC
> fetches only column names and omits the numeric index.
If you would like to return all columns from an sql statement with column keys as table headers, it's as simple as this:
<?php
$dbh = new PDO("DS", "USERNAME", "PASSWORD");
$stmt = $dbh->prepare("SELECT * FROM tablename");
$stmt->execute();
$arrValues = $stmt->fetchAll(PDO::FETCH_ASSOC);
// open the table
print "<table wdith=\"100%\">\n";
print "<tr>\n";
// add the table headers
foreach ($arrValues[0] as $key => $useless){
print "<th>$key</th>";
}
print "</tr>";
// display data
foreach ($arrValues as $row){
print "<tr>";
foreach ($row as $key => $val){
print "<td>$val</td>";
}
print "</tr>\n";
}
// close the table
print "</table>\n";

PHP fetchAll Data From SQL Server 2005
if field's data type is varchar(nvarchar), only fetch 255 chars. but the "text" data type is ok.
so, notice! to change the 'varchar' or 'nvarchar' (length > 255) to 'text' data type..
hope to help u.
<?php
$user = 'sa';
$pass = 'pass';
$conn = new PDO('mssql:host=127.0.0.1; dbname=tempdb;', $user, $pass);
$mainSQL = "SELECT field_varchar, field_text FROM table1";
$sth = $conn->prepare($mainSQL);
$sth->setFetchMode(PDO::FETCH_ASSOC);
$sth->execute();
$retRows = $sth->fetchAll();
// the field_varchar field only to fetch 255 chars(max)
// the field_text is ok.
var_dump($retRows);
unset($sth); unset($conn);

There may be some user who needs to upgrade their MySQL class to PDO class. The way of fetching results were changed from while loop into a foreach loop. For the people who wish to fetch the results in a while loop, here is a simple trick.
<?php
$db = new DB();
$query = $db->prepare("SELECT * FROM CPUCategory");
$query = $db->execute();
$result = $db->fetchAll();
var_dump($result);
?>
The Output will be:
array(2) {
[0]=> array(2) {
["ccatid"]=> int(1)
["ccatname"]=> string(5) "Intel"
}
[1]=> array(2) {
["ccatid"]=> int(2)
["ccatname"]=> string(3) "AMD"
}
}
Never look like the output of old function.
[ORIGINAL STYLE] mysql_fetch_array($query)
[ MYSQL CLASS] $db->fetch_array($query)
And you may give up.
But there is a simple way to use while loop to fetch the results.
<?php
$db = new DB();
$query = $db->prepare("SELECT * FROM CPUCategory");
$query = $db->execute();
$result = $db->fetchAll();
$row = array_shift($result);
// If you need to fetch them now, put it in a while loop just like below:
// while($row = array_shift($result)) { ... }
var_dump($row);
?>
The Output will be in a single array with while loop returns TRUE:
array(2) {
["ccatid"]=> int(1)
["ccatname"]=> string(5) "Intel"
}
So after fetching this row, while loop runs again and fetch the next row until all row has fetched, then the while loop will return false. (Just like the old function did)
When you need to upgrade to PDO class, not much code needs to be modified and remember.

Be careful when using PDO::FETCH_COLUMN with PDO::FETCH_GROUP. By default, results are grouped by first column (index 0) and second column (index 1) is returned. But, if you provide fetch argument, it wouldn't affect returned column, but grouping column. If grouping column is set explicitly , first columns is returned instead of second.
<?php
$insert = $dbh->prepare("INSERT INTO people(id, gender) VALUES (?, ?)");
$insert->execute(array('2', 'female'));
$insert->execute(array('3', 'female'));
$insert->execute(array('4', 'female'));
$insert->execute(array('5', 'male'));
$insert->execute(array('6', 'male'));
$sth = $dbh->prepare("SELECT gender, id FROM people");
$sth->execute();
/* Group values by the first column */
var_dump($sth->fetchAll(PDO::FETCH_COLUMN|PDO::FETCH_GROUP));
?>
Returns:
<?php
array (size=2)
'female' =>
array (size=3)
0 => string '2' (length=1)
1 => string '3' (length=1)
2 => string '4' (length=1)
'male' =>
array (size=2)
0 => string '5' (length=1)
1 => string '6' (length=1)
?>
But,
<?php
var_dump($sth->fetchAll(PDO::FETCH_COLUMN|PDO::FETCH_GROUP, 0));
?>
returns:
<?php
array (size=2)
'female' =>
array (size=3)
0 => string 'female' (length=1)
1 => string 'female' (length=1)
2 => string 'female' (length=1)
'male' =>
array (size=2)
0 => string 'male' (length=1)
1 => string 'male' (length=1)
?>
and
<?php
var_dump($sth->fetchAll(PDO::FETCH_COLUMN|PDO::FETCH_GROUP, 1));
?>
returns
<?php
array (size=5)
2 =>
array (size=1)
0 => string 'female' (length=1)
3 =>
array (size=1)
0 => string 'female' (length=1)
4 =>
array (size=1)
0 => string 'female' (length=1)
5 =>
array (size=1)
0 => string 'male' (length=1)
6 =>
array (size=1)
0 => string 'male' (length=1)
?>
First column is retuned and grouping is done by provided column index.

When passing PDO::FETCH_CLASS as the first argument, this method will accept the class name as the second option:
<?php
$query = $pdo->prepare($sql);
$result = $query->execute($values);
if ($result && $query->rowCount() > 0) {
$records = $query->fetchAll(PDO::FETCH_CLASS, 'Some_Class');
// $record is now an array of Some_Class objects
}
?>

I was having trouble with returning PDO query results in arrays, due to the structure of the results of those queries (query array with arrays for results inside). Now when executing a fetchAll() on a query you get the following:
Array ( [0] = Array ( [key1] => "value1", [key2] => "value2") [1] = Array( [key1] => "value1", [key2] => "value2") )
This is a smaller array, but return results in a HUGE database this way and it quickly becomes IMPPOSIBRU to read out the array given.
This is where the glorious foreach comes in! We all know the basic writing of a foreach (foreach ($array as $key => $value) {...}), but with query results there's a twist, as both the $key AND $value variables are arrays, where $key is the array of the query containing the result arrays and $value is/are the result array(s) themselves.
So in this foreach we have to talk directly to $value to get our results! This would look something like this:
<?php
foreach ($query as $key => $value) {
return $value["key2"];
}
?>
This already does the job, but to return them in arrays we have to change our return code a little bit, like so:
<?php
foreach ($query as $key => $value) {
return array (
"key1" => $value["key1"],
"key2" => $value["key2"]
);
}
?>
This foreach loops through the query array, just like the firs one, but the return code just doesn't return the keys representing the result arrays ($key) and returns only keys from inside the result arrays, stored in $value. This gives us an array looking like this:
Array ( [key1] => "value1", [key2] => "value2")
This should return all the values in your array, if written properly. I'm still having problems with the foreach not returning ALL results, but this note was mainly to show how it can be returned in an array.

In method body:
return $pstmt->fetchAll() or die("bad");
will not return correct value, but "1" instead.

Something missing in the doc.
If for instance you try to fetchAll(PDO::CLASS, "Class") it sometimes return an array of objects with NULL values, but the count of objects fetched correspond to table rows.
In this way works fine:
fetchAll(PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE, "Class");
For example
$stm = $pdo->prepare("SELECT * FROM Fruit");
$stm->execute();
$stm->fetchAll(PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE, "Fruit");

Note, that you can use PDO::FETCH_COLUMN|PDO::FETCH_GROUP pair only while selecting two columns, not like DB_common::getAssoc(), when grouping is set to true.

You might find yourself wanting to use FETCH_GROUP and FETCH_ASSOC at the same time, to get your table's primary key as the array key - use FETCH_UNIQUE also, or you will probably get some unintended behaivor:
<?php
// $stmt is some query like "SELECT rowid, username, comment"
//with unique
$results = $stmt->fetchAll(PDO::FETCH_GROUP|PDO::FETCH_ASSOC|PDO::FETCH_UNIQUE);
$results = array(
1234 => array('username' => 'abc', 'comment' => '[...]'),
1235 => array('username' => 'def', 'comment' => '[...]'),
);
//without unique
$results = $stmt->fetchAll(PDO::FETCH_GROUP|PDO::FETCH_ASSOC);
// It does work, but not as you might expect:
$results = array(
1234 => array(0 => array('username' => 'abc', 'comment' => '[...]')),
1235 => array(0 => array('username' => 'def', 'comment' => '[...]')),
);
?>

I was blown away that you can actually combine PDO::FETCH_CLASS | PDO::FETCH_CLASSTYPE | PDO::FETCH_UNIQUE, because both PDO::FETCH_CLASSTYPE and PDO::FETCH_UNIQUE say they will use the first column, but it turns out PDO::FETCH_CLASSTYPE goes first and then PDO::FETCH_UNIQUE will use the next column. This way you can create an associative array of objects, with one of the table columns as key. For example a query such as
'SELECT Class, Id, t.* FROM subscriptions_tbl t'
might give you this result:
Array
(
[20481086] => WConsumerSubscription Object
(
[Variant] => 2
[_Expiration:WSubscriptionModel:private] => DateTime Object
(
[date] => 2018-08-08 00:00:00.000000
[timezone_type] => 3
[timezone] => UTC
)
[Notes] =>
[Id] => 20481086
[_Deleted:protected] => 0
[_VersionNo:protected] => 2
[ContactId] =>
[ConsumerId] => 2
)
[21878324] => WAdminSubscription Object
(
[Variant] =>
[_Expiration:WSubscriptionModel:private] =>
[Notes] =>
[Id] => 21878324
[_Deleted:protected] => 0

If you are trying to call PDOStatement::fetchAll and is not getting the result set as expected (empty instead), check if you called PDOStatement::execute first.
Remember PDOStatement::fetchAll does not execute the query, it just mounts the array.
:)
