#45646 [Opn->Csd]: Failed Connect Does Not Return FALSE

ID: 45646 Updated by: kalle@php.net Reported By: djneoform at gmail dot com -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: Win2k3 Standard PHP Version: 5.2.6 -Assigned To: +Assigned To: kalle New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. I changed the return values, and fixed the connect example to use proper OO syntax and added a notice explaining how to find out if a connection failed. Previous Comments: ------------------------------------------------------------------------ [2008-07-29 21:04:26] djneoform at gmail dot com What then is the proper way to verify that a connection has been established while using the OO version? It seems innapropriate to be using a class object, only to use mysqli_connect_errno() in order to verify that the connection was established. ------------------------------------------------------------------------ [2008-07-29 21:01:44] jani@php.net The manual page isn't quite clear that this concerns only the procedural style connect, not the OO way. ------------------------------------------------------------------------ [2008-07-28 14:49:21] djneoform at gmail dot com Description: ------------ When a mysqli connection fails, the returned value is an empty mysqli object and not a bool(FALSE), this means any tests on the connection will not work, eg: if ($conn) { ... } When the documentation: http://ca.php.net/manual/en/mysqli.connect.php States: "Return Values Returns a object which represents the connection to a MySQL Server or FALSE if the connection failed." Reproduce code: --------------- <?php $connection = new mysqli('localhost', 'badinfo', 'badinfo', 'badinfo'); var_dump($connection); ?> Expected result: ---------------- bool(FALSE) Actual result: -------------- object(mysqli)#1 (0) { } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45646&edit=1
