ID: 52198 Comment by: christian dot gnoth at arcor dot de Reported by: christian dot gnoth at arcor dot de Summary: strpos not working correctly Status: Bogus Type: Bug Package: Strings related Operating System: Linux PHP Version: 5.2.13 New Comment: Hello, thank you for your qualified answer. But, please take a look at the following lines: $strpos_ret = strpos( $post_lnk_string, 'article&id='); echo 'Post ID: ' . $j2wp_post['ID'] . ' link: ' . $post_lnk_string . ' :' . $strpos_ret . ':<br />'; and here is the output: Post ID: 107 link: href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97" :: So the strpos function has no idea from were the input is comming. Infact it is for the problem not intresting. Question is, from which memory area it gets the input and what is there and how it is moved to the strpos function. The variable which is passed to strpos contains the string 'article&id=', but this string is not found by the strpos function. So it is a bug in the PHP interpreter!!! As you are the developer you should see that!!! Previous Comments: ------------------------------------------------------------------------ [2010-07-04 21:42:50] paj...@php.net Please understand that strpos has absolutely no idea where the strings you pass it come from (ich meine es: echt keine Ahnung). What is so hard to understand to actually do what Rasmus has been asking for a week now? Provide a script like the one I wrote in my previous comment. If you can't reproduce it using such a simple script, then something is wrong somewhere else in your code. If you keep need support, I would suggest to go to either the php-general mailing or to whatever is the support channel for Wordpress. But bugs.php.net is not such channel. Thanks for your understanding. ------------------------------------------------------------------------ [2010-07-04 21:36:37] christian dot gnoth at arcor dot de to reproduce this case is not simple, the script is part of a wordpress plugin and runs within the wordpress environment with mysql access. It is a Joomla to Wordpress Migrator. It reads the Joomla tables and inserts the entries in the wordpress posts table. After that the URL's within the posts can be changed and pointed to the new wordpress posts. I have provided the source code and the mysql table structure under: http://files.it-gnoth.de/download/php_report/ To have the same environment for this case you have to do the following steps: - install wordpress (I have the multisite feature enabled) - import the sql file I proved into the mysql database - it contains the joomla content entries - install the plugin in wordpress - fill up the mysql connection parameters in the plugin admin panel - start the migration of the joomla content to wordpress - start the url change proccess ------------------------------------------------------------------------ [2010-07-04 20:09:23] ras...@php.net We don't want you to give us a case where it doesn't happen. We want you to come up with a simpler version of your code where the problem *does* happen. And we have looked at the source code you have provided and there is nothing visually wrong with it. Without an actual reproducing case, there is nothing we can do, and you still have not provided that. ------------------------------------------------------------------------ [2010-07-04 19:46:59] christian dot gnoth at arcor dot de Hello, I can not follow you how you come to the idea not to analyze the given source code of a bug report, simply because you do not want use your mind to understand the logic of the source code. For this report I made the echos in the source code that you can see the content of the variable passed to the strpos function. As I wrote many times, I do not doubt that the strpos function is working in a different case and as I wrote it is working in different places in my sourcecode. BUT !!!! As you can see strpos is not able to find: 'article&id=' in href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97" in the cylcle of many nested function calls. So - it is not a question of "strpos is working or not", but as I think a question of memory areas which may be not correct filled, passed, handled..... And for that problem it is of no use to create other circumstances where this problem is not happening. ------------------------------------------------------------------------ [2010-07-04 19:09:39] mchl at flingbits dot com Let me get this straight. strpos() is used in thousands of applications around the world, and none are experiencing this problem except yours. You claim therefore that this is a PHP bug. I'm sorry, but the odds are against you. You also say, that because you reported it as a PHP bug it should be treated as such. I'm sorry again, but it doesn't work this way. Until you can convince us that the problem is not with YOUR code, it will be treated as a bogus report. You can convince us by providing a simple code, that reproduces this behaviour, but does not rely on external resources like database or unknown global variables. If you can't produce such code, it's indicating you're looking in the wrong place. Personally I would advise using var_dump() before strpos() to see if haystack actually contains needle. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
