#31045 [WFx]: Testing return value of simplexml_load_string

ID: 31045 User updated by: rbro at hotmail dot com Reported By: rbro at hotmail dot com Status: Wont fix Bug Type: SimpleXML related Operating System: Linux PHP Version: 5CVS-2004-12-09 (dev) New Comment: Thanks - that makes sense with how simplexml works. So others don't run into this, would it be possible add to the manual a warning about this on the simplexml_load_string and simplexml_load_file pages? It's basically the same idea as the warning currently on http://www.php.net/strpos. Thanks. Previous Comments: ------------------------------------------------------------------------ [2004-12-15 13:04:17] chregu@php.net really not a bug. simplexml returns an empty string in your case (no text content in <xml>), which is == false in PHP's loosely typed implementation. Just use === and it works as expected ------------------------------------------------------------------------ [2004-12-14 09:07:38] derick@php.net If we have updates, we'll get back to you. No need to keep bugging us. ------------------------------------------------------------------------ [2004-12-13 20:36:28] rbro at hotmail dot com Just wondering if there is any update on this. I really feel that this is a bug because there is a difference between the way the mysqli and simplexml objects work (between the mysqli_connect() and simplexml_load_string() functions) - since objects should work the same across the board. Thanks. ------------------------------------------------------------------------ [2004-12-10 00:08:58] rbro at hotmail dot com Sorry, that code example should have been the following (same result happens): <?php if (($db = mysqli_connect('localhost', 'user', 'password', 'db')) == false) { echo 'equals false'; } else { echo 'does not equal false'; } ?> ------------------------------------------------------------------------ [2004-12-10 00:07:39] rbro at hotmail dot com Ok, but then why does this work as expected (when a valid host, username, password, and db are supplied): Reproduce code: --------------- <?php if (($db = mysqli_connect('localhost', 'user', 'password', 'db')) === false) { echo 'equals false'; } else { echo 'does not equal false'; } ?> Expected result: ---------------- does not equal false Actual result: -------------- does not equal false ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
