PDOStatement {
  bool setFetchMode(int mode);
}
PDOStatement {
  bool setFetchMode(int PDO::FETCH_COLUMN,
                    int colno);

}
PDOStatement {
  bool setFetchMode(int PDO::FETCH_CLASS,
                    string classname,
                    array ctorargs);

}
PDOStatement {
  bool setFetchMode(int PDO::FETCH_INTO,
                    object object);

}

Parameters

mode

The fetch mode must be one of the PDO::FETCH_* constants.

Examples

Example 1794. Setting the fetch mode

The following example demonstrates how PDOStatement->setFetchMode() changes the default fetch mode for a PDOStatement object.

<?php
$sql
= 'SELECT name, colour, calories FROM fruit';
try {
 
$stmt = $dbh->query($sql);
 
$result = $stmt->setFetchMode(PDO::FETCH_NUM);
 while (
$row = $stmt->fetch()) {
   print
$row[0] . "\t" . $row[1] . "\t" . $row[2] . "\n";
 }
}
catch (
PDOException $e) {
 print
$e->getMessage();
}
?>

The above example will output:

apple   red     150
banana  yellow  250
orange  orange  300
kiwi    brown   75
lemon   yellow  25
pear    green   150
watermelon      pink    90
