mysql_fetch_lengths — Get the length of each output in a result
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:
Returns an array that corresponds to the lengths of each field in the last row fetched by MySQL.
mysql_fetch_lengths() stores the lengths of each result column in the last row returned by mysql_fetch_row(), mysql_fetch_assoc(), mysql_fetch_array(), and mysql_fetch_object() in an array, starting at offset 0.
result
The result resource that is being evaluated. This result comes from a call to mysql_query().
Example #1 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 )
