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: what will be enlightening to me if I know that the strpos function is working in a simple script and with a static string passed, but not in big script with different function calls? What I have if I proove the strpos is working, but in the that case not? I provided the source code here. In the directory you will find the .php files which you can download - I see in the browser a direcotry list. f you want I can provide a MySQL dump and the php scripts as .zip file. But the source code is above of the whole function. Previous Comments: ------------------------------------------------------------------------ [2010-06-28 19:21:29] ras...@php.net By the way, even if I was inclined to look through your code, you haven't provided it. The http://joomla-wp.it-gnoth.de/wp-content/plugins/joomla2wp/ link is useless since it doesn't serve up a visible version of the scripts there. ------------------------------------------------------------------------ [2010-06-28 19:13:54] ras...@php.net No, you need to take the time to simplify your case into a standalone test that proves your point instead of asking us to weed through a lot of code. There is absolutely nothing wrong with the strpos function, so the exercise of producing a standalone test will be enlightening for you. You can choose not to believe me, I suppose, that is entirely up to you. ------------------------------------------------------------------------ [2010-06-28 19:10:28] christian dot gnoth at arcor dot de of what use is it to proove something what is working??? That there is no difference is not true!!! if I pass a constant string always each function call it is different than to pass variable which content is with each call different. Means the memory for the static string remains always equal with each call, but the memory area of the variable is always differnet - in place (I think with each call the variable is allocated again, or?) and in content. So please take the time and look through the code I provided - you can see clearly that the output is generated at the end of the else tree in which the PHP interpreter should never go!!! The output is generated of the variable $post_lnk_string echo 'Post ID: ' . $j2wp_post['ID'] . ' link: ' . $post_lnk_string . '<br />'; the if: if ( !(strpos( $post_lnk_string, 'article&id=') === false) ) should not allow that to happen!!!!! and as you can see in 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" :: Post ID: 107 link: href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97" :40: Post ID: 107 link: href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97" from the source code: $strpos_ret = strpos( $post_lnk_string, 'article&id='); echo 'Post ID: ' . $j2wp_post['ID'] . ' link: ' . $post_lnk_string . ' :' . $strpos_ret . ':<br />'; $strpos_ret = strpos( 'href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97"', 'article&id='); echo 'Post ID: ' . $j2wp_post['ID'] . ' link: ' . 'href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97"' . ' :' . $strpos_ret . ':<br />'; // urls with structure: href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97" // if ( $pos_article_id = strpos( $post_lnk_string, 'article&id=') ) if ( !(strpos( $post_lnk_string, 'article&id=') === false) ) the problem is not with the if, but with the strpos function !!!! Please take the time and look through this code examples and the generated output!!! ------------------------------------------------------------------------ [2010-06-28 18:58:44] ras...@php.net The test script I showed you used variables, not static strings. My guess (since I can't decipher your messy code) is that your POST data is probably getting parsed or filtered and the contents isn't what you think it is. Your & might actually be & so the strpos isn't going to match. Look for issues along those lines. strpos works fine, so the longer you keep blaming strpos the longer it will take you to find your bug. ------------------------------------------------------------------------ [2010-06-28 18:26:24] paj...@php.net If you are experiencing a problem with strpos and variables, then please provide a script similar to: $haystack = "some content"; $needle = "content"; if (strpos($haystack, $needle) === false)) { echo "not found\n"; } else { echo "found\n"; } Everything else is irrelevant. However, as Rasmus said, there is no difference in strpos if you pass a static variable or a string. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
