PHP-函数 Informix ifx_connect

(PHP 4, PHP <=5.2.0)ifx_connect — Open Informix server connection



说明

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().



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 a connection identifier on success, or FALSE on error.



范例

Example #1 Connect to a Informix database

<?php
$conn_id = ifx_connect ("mydb@ol_srv1", "imyself", "mypassword");
?>
