msql_pconnect - Open persistent mSQL connection

SYNOPSIS
       resource msql_pconnect ([string	$hostname])

DESCRIPTION
       msql_pconnect(3) acts very much like msql_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. 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(3) will not close links established by this function).

PARAMETERS
	      o $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.

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