mysql_pconnectOpen a persistent connection to a MySQL server 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:
Description
resource mysql_pconnect(
string $server = ini_get("mysql.default_host"),string $username = ini_get("mysql.default_user"),string $password = ini_get("mysql.default_password"),int $client_flags = 0) Establishes a persistent connection to a MySQL server. mysql_pconnect acts very much like mysql_connect with two major differences. First, when connecting, the function would first try to find a (persistent) link that's already open with the same host, username and password. If one is found, an identifier for it will be returned instead of opening a new connection. Second, the connection to the SQL server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (mysql_close will not close links established by mysql_pconnect). This type of link is therefore called 'persistent'. Parameters
Return Values
Returns a MySQL persistent link identifier on success, or Notes
Warning
Using persistent connections can require a bit of tuning of your Apache and MySQL configurations to ensure that you do not exceed the number of connections allowed by MySQL. |
