Example #1
A mysql_fetch_lengths(3) 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
)
mysql_field_len(3), mysql_fetch_row(3), strlen(3).
