PHP 5.4.33 Released

msql_pconnect

(PHP 4, PHP 5)

msql_pconnectOpen persistent mSQL connection

说明

resource msql_pconnect ([ string $hostname ] )

msql_pconnect() acts very much like msql_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. 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 (msql_close() will not close links established by this function).

参数

hostname

The hostname can also include a port number. e.g. hostname,port.

If not specified, the connection is established by the means of a Unix domain socket, being more efficient than a localhost TCP socket connection.

Note: While this function will accept a colon (:) as a host/port separator, a comma (,) is the preferred method.

返回值

Returns a positive mSQL link identifier on success, or FALSE on error.
