ifx_pconnect — Open persistent Informix connection
Description
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.
