MYSQL_PCONNECT(3) 1 MYSQL_PCONNECT(3) mysql_pconnect - Open a persistent connection to a MySQL server SYNOPSIS
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: omysqli_connect(3) with p: host prefix o PDO::__construct with PDO::ATTR_PERSISTENT as a driver option 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]) DESCRIPTION
Establishes a persistent connection to a MySQL server. mysql_pconnect(3) acts very much like mysql_connect(3) 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(3) will not close links established by mysql_pconnect(3)). This type of link is therefore called 'persistent'. o $server - The MySQL server. It can also include a port number. e.g. "hostname:port" or a path to a local socket e.g. ":/path/to/socket" for the localhost. If the PHP directive mysql.default_host is undefined (default), then the default value is 'localhost:3306' o $username - The username. Default value is the name of the user that owns the server process. o $password - The password. Default value is an empty password. o $client_flags - The $client_flags parameter can be a combination of the following constants: 128 (enable LOAD DATA LOCAL handling), MYSQL_CLIENT_SSL, MYSQL_CLIENT_COMPRESS, MYSQL_CLIENT_IGNORE_SPACE or MYSQL_CLIENT_INTERACTIVE. Returns a MySQL persistent link identifier on success, or FALSE on failure. +--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.5.0 | | | | | | | This function will generate an E_DEPRECATED | | | error. | | | | +--------+---------------------------------------------------+ Note Note, that these kind of links only work if you are using a module version of PHP. See the Persistent Database Connections section for more information. 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. Note You can suppress the error message on failure by prepending a @ to the function name. mysql_connect(3), Persistent Database Connections. PHP Documentation Group MYSQL_PCONNECT(3)
