mysql_get_proto_info

Get MySQL protocol info

Warning

This extension is deprecated as of PHP 5.5.0, and will be removed in the future. 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_get_proto_info

Description

int 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 was 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
