ifx_pconnect

(PHP 4, PHP 5 < 5.2.1)

ifx_pconnect — Open persistent Informix connection

说明

ifx_pconnect ([ string $database [, string $userid [, string $password ]]] ) : resource

ifx_pconnect() acts very much like ifx_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 (ifx_close() will not close links established by ifx_pconnect()).

This type of links is therefore called 'persistent'.

参数

All of the arguments are optional, and if they're missing, defaults are taken from values supplied in php.ini (ifx.default_host for the host (Informix libraries will use INFORMIXSERVER environment value if not defined), ifx.default_user for user, ifx.default_password for the password (none if not defined).

database: The database name, as a string.
userid: The username, as a string.
password: The password, as a string.

返回值

Returns: valid Informix persistent link identifier on success, or FALSE on errors.
