Example #1 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
