mysql_get_host_info — Get MySQL host 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 and related FAQ for more information. Alternatives to this function include:

• mysqli_get_host_info()
• PDO::getAttribute(PDO::ATTR_CONNECTION_STATUS)

Description

mysql_get_host_info ([ resource $link_identifier = NULL ] ) : string|false

Describes the type of connection in use for the connection, including the server host name.

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 a string describing the type of MySQL connection in use for the connection or FALSE on failure.

Examples

Example #1 mysql_get_host_info() example

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

The above example will output something similar to:

MySQL host info: Localhost via UNIX socket
