Examples

Example 20.37. A mysql_fetch_lengths example

<?php
$result = mysql_query('SELECT id,email FROM people WHERE id = '42'');
if (!$result) {
 echo 'Could not run query: ' . mysql_error();
 exit;
}
$row = mysql_fetch_assoc($result);
$lengths = mysql_fetch_lengths($result);
print_r($row);
print_r($lengths);
?>
