sybase_connect

SYBASE_CONNECT(3)														 SYBASE_CONNECT(3)

sybase_connect - Opens a Sybase server connection

SYNOPSIS

       resource  sybase_connect  ([string   $servername],  [string  $username], [string  $password], [string  $charset], [string  $appname], [bool
       $new = false])

DESCRIPTION

       sybase_connect(3) establishes a connection to a Sybase server.

	In case a second call is made to sybase_connect(3) with the same arguments, no new link will be established, but instead, the link identi-
       fier of the already opened link will be returned.

	The  link  to  the  server  will  be  closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling
       sybase_close(3).

PARAMETERS

	      o $servername
		- The servername argument has to be a valid servername that is defined in the 'interfaces' file.

	      o $username
		- Sybase user name

	      o $password
		- Password associated with $username.

	      o $charset
		- Specifies the charset for the connection

	      o $appname
		- Specifies an appname for the Sybase connection. This allow you to make separate connections in the same script to the same data-
		base. This may come handy when you have started a transaction in your current connection, and you need to be able to do a separate
		query which cannot be performed inside this transaction.

	      o $new
		- Whether to open a new connection or use the existing one.

RETURN VALUES

	Returns a positive Sybase link identifier on success, or FALSE on failure.
