ibase_fetch_row

(PHP 5)

ibase_fetch_rowLit une ligne d'une base Interbase

Description

array ibase_fetch_row ( resource $result_identifier [, int $fetch_flag = 0 ] )

ibase_fetch_row() récupère une ligne de données depuis le jeu de résultats donné.

Les appels suivants à ibase_fetch_row() vont retourner la prochaine ligne dans le résultat, ou bien FALSE s'il n'y a plus de ligne.

Liste de paramètres

result_identifier

Un identifiant de résultat InterBase.

fetch_flag

fetch_flag est une combinaison des constantes IBASE_TEXT et IBASE_UNIXTIME. Passer IBASE_TEXT fait retourner le contenu du BLOB au lieu de l'ID du BLOB. Passer IBASE_UNIXTIME fait retourner les valeurs date/time sous forme de timestamps UNIX au lieu de chaînes formatées.

Valeurs de retour

Retourne un tableau correspondant à la ligne récupérée, ou FALSE s'il n'y a plus de ligne. Chaque colonne du résultat est stockée dans une position du tableau, en commençant à 0.

If you have a query

"select ... from table1 where ..."

and would like to know the cardinality of the result set by issuing a separate query

"select count(*) from table1 where ..."

then you might end up with an incorrect value since an insert or delete can occur between the running of these queries (unlikely, but possible).
The only way i can think of getting the correct value would be something along the lines of

<?php

$qry
= "select ... from table1 where ...";
$result = ibase_query($tr, $qry) // assume $tr is a transaction

$count = 0;
while (
$row[$count] = ibase_fetch_assoc($result))
   
$count++;

?>

then $count is the cardinality, and $row the result set.
Then you can work with the result set:

<?php

for ($i = 0; $i < $count; $i++)
{
 
// do something with $row[$i]
}

?>

I had some troubles with moving php application from one dbase to another. From SyBase to Interbase.
Especially with missing function "ibase_num_rows($result)".

These are functions that helped me.
<?php
...
$dbh = ibase_connect ($host, $username, $password);
...
$ar_count_queries = array();

function
ibasequery($query) {
 
$cquery = preg_replace("/SELECT(.*?)FROM(.*?)/","SELECT COUNT(*) FROM \\2",$query);
  if (
$cquery != $query) {
  
$crow=get_object_vars( ibase_fetch_object( ibase_query( $GLOBALS["dbh"], $cquery ) ) );
   }
  @
$res = ibase_query($GLOBALS["dbh"],$query);
  if (isset(
$res)) {
    if (isset(
$crow)) {
    
$GLOBALS["ar_count_queries"][$res] = $radcountselect["COUNT"];
    }
    return
$res;
  }
   return
false;
}

function
ibasenumrows($result) {
  return
$GLOBALS["ar_count_queries"][$res];
}

function
ibasefetchrow($result) {
  return
get_object_vars(ibase_fetch_object($result));
}

// example
$result = ibasequery("SELECT * FROM TABLE");
$numrows = ibasenumrows($result);
echo
"Number of rows: $numrows.\nContent: \n";
while (
$onerow = ibasefetchrow($res)) {
  foreach(
$onerow as $key => $value) {
    echo
$key.": ".$value.", ";
  }
  echo
"\n";
}
?>
