mysql_get_proto_info

Get MySQL protocol info

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. Alternatives to this function include:

mysqli_get_proto_info

Description

intfalse mysql_get_proto_info(resource $link_identifier = NULL)

Retrieves the MySQL protocol.

Parameters

link_identifier: The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect is assumed. If no such link is found, it will try to create one as if mysql_connect had been called with no arguments. If no connection is found or established, an E_WARNING level error is generated.

Return Values

Returns the MySQL protocol on success or false on failure.

Examples

Example #1 mysql_get_proto_info example

<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
printf("MySQL protocol version: %s\n", mysql_get_proto_info());
?>

The above example will output something similar to:

MySQL protocol version: 10
