ingres_pconnect - Open a persistent connection to an Ingres database

SYNOPSIS

       resource ingres_pconnect ([string  $database], [string  $username], [string  $password], [array	$options])

DESCRIPTION

	Open a persistent connection to an Ingres database.

	There  are  only  two  differences between this function and ingres_connect(3): First, when connecting, the function will initially try to
       find a (persistent) link that is 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 Ingres server will not be closed when the execution of the script ends. Instead,
       the link will remain open for future use (ingres_close(3) will not close links established by ingres_pconnect(3)). This	type  of  link	is
       therefore called "persistent".

PARAMETERS

	      o $database
		- The database name. Must follow the syntax: $[vnode::]dbname[/svr_class]

	      o $username
		- The Ingres user name

	      o $password
		- The password associated with $username

	      o $options
		- See ingres_connect(3) for the list of options that can be passed

RETURN VALUES

	Returns an Ingres link resource on success or FALSE on failure

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);
	      ?>
