PHP : Function Reference : MySQL Functions : mysql_fetch_lengths

mysql_fetch_lengths

Get the length of each output in a result (PHP 4, PHP 5, PECL mysql:1.0)
array mysql_fetch_lengths ( resource result )

Example 1432. 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);
?>

The above example will output something similar to:

Array
(
   [id] => 42
   [email] => user@example.com
)
Array
(
   [0] => 2
   [1] => 16
)
