ifx_connect

Open Informix server connection

&reftitle.description; `resource` `ifx_connect` `string` `database` `string` `userid` `string` `password`

`ifx_connect` establishes a connection to an Informix server.

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`.

&reftitle.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.

&reftitle.returnvalues;

Returns a connection identifier on success, or &false; on error.
