ifx_connect -- Open Informix server connection
Description
int
ifx_connect ( [string database [, string userid [, string password]]] )
Returns a connection identifier on success, or FALSE on
error.
ifx_connect() establishes a connection to an
Informix server. All of the arguments are optional, and if
they're missing, defaults are taken from values supplied in configuration file
(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).
In case a second call is made to
ifx_connect() with the same arguments, no
new link will be established, but instead, the link identifier of
the already opened link will be returned.
The link to the server will be closed as soon as the execution of
the script ends, unless it's closed earlier by explicitly calling
ifx_close().
