# sybase_pconnect

(PHP 3 <= 3.0.18, PHP 4 >= 4.0.0)

sybase_pconnect -- open persistent Sybase connection

## Description

``int sybase_pconnect` (string servername, string username, string password [, string charset])`

Returns: A positive Sybase persistent link identifier on success, or `FALSE` on error

sybase_pconnect() acts very much like sybase_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, 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 (sybase_close() will not close links established by sybase_pconnect()()).

This type of links is therefore called 'persistent'.
