ingres_pconnect

(PHP 4 >= 4.0.2, PHP 5)

ingres_pconnect --  Open a persistent connection to an Ingres II database

Description

resource ingres_pconnect ( [string database [, string username [, string password]]] )

警告

本函数是实验性的。本函数的行为,包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

Returns a Ingres II link resource on success, or FALSE on failure.

See ingres_connect() for parameters details and examples. There are only 2 differences between ingres_pconnect() and ingres_connect() : 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 Ingres server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (ingres_close() will not close links established by ingres_pconnect()). This type of link is therefore called 'persistent'.

See also ingres_connect() and ingres_close().
