mysql_fetch_lengths — Get the length of each output in a result

Warning

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 and related FAQ for more information. Alternatives to this function include:

- mysqli_fetch_lengths()
- PDOStatement::getColumnMeta()

### Description

mysql_fetch_lengths ( resource `$result` ) : array|false

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.

### Parameters

`result`

  The result resource that is being evaluated. This result comes from a call to mysql_query().

### Return Values

An array of lengths on success or `FALSE` on failure.

### Examples

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
    )
