# mssql_pconnect

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

mssql_pconnect -- Open persistent MS SQL connection

## Description

``int mssql_pconnect` ([string servername [, string username [, string password]]])`

Returns: A positive MS SQL persistent link identifier on success, or `FALSE` on error.

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

This type of links is therefore called 'persistent'.
