sqlite_fetch_string
This code works with SQlite version 3 databases.
<?php
function sqlite_field_names($dbfile, $tablename){
try
{
$db = new PDO("sqlite:".$dbfile);
$sql=$db->query("SELECT sql FROM sqlite_master WHERE tbl_name='".$tablename."'");
foreach($sql as $row)
{
$fields = $row["sql"];
}
$db = NULL;
}
catch(PDOException $e)
{
print "Exception : ".$e->getMessage();
}
$cut=strtok($fields,"(");
while($fieldnames[]=strtok(",")) {};
array_pop($fieldnames);
foreach($fieldnames as $no => $field)
if (strpos($field, "PRIMARY KEY")){
strtok($field,"(");
$primary=strtok(")");
unset($fieldnames[$no]);
} else
$fieldnames[$no]=strtok($field, " ");
return $fieldnames;
}
print_r(array_values(sqlite_field_names($dbfile, $tablename)));
?>
sqlite_field_name
SQLiteResult->fieldName
SQLiteUnbuffered->fieldName
(PHP 5, PECL sqlite >= 1.0.0)
sqlite_field_name -- SQLiteResult->fieldName -- SQLiteUnbuffered->fieldName — Gibt den Namen eines Feldes zurück
Beschreibung
string sqlite_field_name
( resource $result
, int $field_index
)
Objektorientierter Stil (Methode):
string SQLiteResult::fieldName
( int $field_index
)
string SQLiteUnbuffered::fieldName
( int $field_index
)
Übergibt man die Ordnungszahl einer Spalte field_index, wird sqlite_field_name() den Namen des Feldes im Abfrageergebnis result zurückgegeben.
Parameter-Liste
- result
-
Die SQLite-Ergebnisressource. Dieser Parameter wird in der objektorientierten Notation nicht benötigt.
- field_index
-
Die Ordnungszahl der Spalte im Abfrageergebnis.
Rückgabewerte
Liefert den Namen eines Feldes in einem SOLite-Ergebnis, identifiziert bei der Ordnungszahl einer Spalte; FALSE im Fehlerfall.
Die Groß- und Kleinschreibung der Spaltennamen, die von SQLITE_ASSOC und SQLITE_BOTH zurückgegeben werden, wird entsprechend der Konfigurationsdirektive sqlite.assoc_case geändert.

It's not the most elegant way, but it works:
<?php
function sqlite_field_names($db, $tablename){
$sq5=sqlite_single_query($db, "SELECT sql FROM sqlite_master WHERE tbl_name='".$tablename."'", SQLITE_NUM);
$kommando=$sq5[0];
$cut=strtok($kommando,"(");
while($fieldnames[]=strtok(",")) {};
array_pop($fieldnames);
foreach($fieldnames as $no => $field)
if (strpos($field, "PRIMARY KEY")){
strtok($field,"(");
$primary=strtok(")");
unset($fieldnames[$no]);
} else
$fieldnames[$no]=strtok($field, " ");
return $fieldnames;
}
?>

While working with SQLite using its object-oriented mode, I found need to display a column/field name without knowing what it was in advance. I couldn't find any examples on the Internet, just this document. So, for anyone who happens to need to do this, here's an example.
<?php
$db = "db/database.sqlite";
// create new database (OO interface)
$dbo = new SQLiteDatabase("$db");
// create table foo and insert sample data
$dbo->query("
CREATE TABLE foo(id INTEGER PRIMARY KEY, name CHAR(255));
INSERT INTO foo (name) VALUES('Ilia1');
INSERT INTO foo (name) VALUES('Ilia2');
INSERT INTO foo (name) VALUES('Ilia3');
");
$query = "SELECT * FROM foo;";
$result = $dbo->query($query) or die("Error in query");
echo "
<table border='1' cellpadding='10'>
<tr>
<td>".$result->fieldName(0)."</td>
<td>".$result->fieldName(1)."</td>
</tr>";
// iterate through the retrieved rows
while ($result->valid()) {
// fetch current row
$row = $result->current();
echo "
<tr>
<td>".$row[0]."</td>
<td>".$row[1]."</td>
</tr>";
// proceed to next row
$result->next();
}
echo "</table>";
?>
