# mysql_get_host_info

(PHP 4 >= 4.0.5, PHP 5)

mysql_get_host_info — Get MySQL host 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_host_info()
- PDO::getAttribute(PDO::ATTR_CONNECTION_STATUS)

### Description

string mysql_get_host_info ([ resource `$link_identifier` = NULL ] )

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() was 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
