  • mysql_get_host_info

    Get MySQL host info


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:



string mysql_get_host_info(resource link_identifier= =NULL);

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



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.


Example 5.34 mysql_get_host_info example

$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$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
