mssql_pconnect - Open persistent MS SQL connection

SYNOPSIS

       resource mssql_pconnect ([string  $servername], [string	$username], [string  $password], [bool	$new_link = false])

DESCRIPTION

       mssql_pconnect(3) acts very much like mssql_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 (mssql_close(3) will not close links established by mssql_pconnect(3)).

	This type of links is therefore called 'persistent'.

PARAMETERS

	      o $servername
		- The MS SQL server. It can also include a port number. e.g.  hostname:port.

	      o $username
		- The username.

	      o $password
		- The password.

	      o $new_link
		-  If  a  second call is made to mssql_pconnect(3) with the same arguments, no new link will be established, but instead, the link
		identifier of the already opened link will be returned. This parameter modifies this behavior and makes  mssql_pconnect(3)  always
		open a new link, even if mssql_pconnect(3) was called before with the same parameters.

RETURN VALUES

	Returns a positive MS SQL persistent link identifier on success, or FALSE on error.

EXAMPLES

       Example #1

	      mssql_pconnect(3) using the $new_link parameter

	      <?php
	      // Connect to MSSQL and select the database
	      $link1 = mssql_pconnect('MANGOSQLEXPRESS', 'sa', 'phpfi');
	      mssql_select_db('php', $link1);

	      // Create a new link
	      $link2 = mssql_pconnect('MANGOSQLEXPRESS', 'sa', 'phpfi', true);
	      mssql_select_db('random', $link2);
	      ?>

ibase_pconnect - Open a persistent connection to an InterBase database

SYNOPSIS

       resource  ibase_pconnect  ([string   $database],  [string   $username],	[string   $password],  [string	 $charset],  [int  $buffers], [int
       $dialect], [string  $role], [int  $sync])

DESCRIPTION

	Opens a persistent connection to an InterBase database.

       ibase_pconnect(3) acts very much like ibase_connect(3) with two major differences.

	First, when connecting, the function will first try to find a (persistent) link that's already opened with the same parameters. If one	is
       found, an identifier for it will be returned instead of opening a new connection.

	Second,  the  connection  to  the InterBase server will not be closed when the execution of the script ends. Instead, the link will remain
       open for future use (ibase_close(3) will not close links established by ibase_pconnect(3)). This type of link is therefore called  'persis-
       tent'.

PARAMETERS

	      o $database
		-  The $database argument has to be a valid path to database file on the server it resides on. If the server is not local, it must
		be prefixed with either 'hostname:' (TCP/IP), '//hostname/' (NetBEUI) or 'hostname@' (IPX/SPX), depending on the connection proto-
		col used.

	      o $username
		- The user name. Can be set with the ibase.default_user php.ini directive.

	      o $password
		- The password for $username. Can be set with the ibase.default_password php.ini directive.

	      o $charset
		-$charset is the default character set for a database.

	      o $buffers
		-$buffers  is  the  number  of	database  buffers  to  allocate for the server-side cache. If 0 or omitted, server chooses its own
		default.

	      o $dialect
		-$dialect selects the default SQL dialect for any statement executed within a connection, and it defaults to the highest one  sup-
		ported by client libraries. Functional only with InterBase 6 and up.

	      o $role
		- Functional only with InterBase 5 and up.

	      o $sync
		-

RETURN VALUES

	Returns an InterBase link identifier on success, or FALSE on error.
