ifx_pconnect

Open persistent Informix connection

Description

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

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'.

Parameters

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.

Return Values

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