# msql_pconnect

(PHP 4, PHP 5)

msql_pconnect — Open persistent mSQL connection

### Description

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).

### Parameters

`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 then more efficient then a localhost TCP socket connection.

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

### Return Values

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