#21497 [Bgs]: include() of XML document fails

ID: 21497 Updated by: jtate@php.net Reported By: polone at townnews dot com Status: Bogus Bug Type: Scripting Engine problem Operating System: RedHat Linux 6.2 PHP Version: 4.3.0 New Comment: This will not be fixed by any current member of the PHP development group. If you desire a fix, submit a patch (though some have already tried and haven't been sucessfull in getting the patches accepted), otherwise, remove all your short tags. There are a number of problems with using short tags, and therefore reasons that you shouldn't use them in your code. The most prominent is that using short tags makes your code essentially non-portable. This from the current php.ini: ; Allow the <? tag. Otherwise, only <?php and <script> tags are recognized. ; NOTE: Using short tags should be avoided when developing applications or ; libraries that are meant for redistribution, or deployment on PHP ; servers which are not under your control, because short tags may not ; be supported on the target server. For portable, redistributable code, ; be sure not to use short tags.

Indeed, polone is right that disabling short tags shouldn't be the solution. I say this because a lot of people are already using <?=$var?> to simply echo variables. If they for one case also encountered the same problem as we have, then he has to rewrite the code where <?= is located. Besides, short tags is a feature that helps a lot. ------------------------------------------------------------------------ [2003-01-07 14:17:17] polone at townnews dot com That does fix the problem, but enabling short open tags shouldn't invalidate properly formatted processing instructions for something other than PHP. In addition, this cannot be altered or disabled by ini_set() from a PHP script (perhaps a security risk?) at run-time. ------------------------------------------------------------------------ [2003-01-07 13:17:31] edink@php.net Disable short_open_tags in your php.ini and the problem will go away. ------------------------------------------------------------------------ [2003-01-07 13:15:12] polone at townnews dot com When using the include(), include_once(), require(), or require_once() functions, documents beginning with: <?xml version="1.0"?> fail to be loaded. I'm guessing this might have to do with PHP trying to interpret the <?xml as <?php, causing a fatal error. Proper operation should check for the processing instruction (PI) value of <?, that is: <? or <?php maybe interpreted as PHP, but not, <?some_other_text at the very least, not: <?xml ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21497&edit=1
