Bug #52198 [NEW]: strpos not working correctly

From: Operating system: Linux PHP version: 5.2.13 Package: Strings related Bug Type: Bug Bug description:strpos not working correctly Description: ------------ Hello, I try to find a string in another string using strpos. If both the string are passed to the strpos function enclosed in ' it is working properly and the position is returned. If I put the string - in which the other string has to be find - in a variable and pass the variable to the strpos function I get FALSE. Maybe a problem of character conversion or php configuration???? the website is: joomla-wp.it-gnoth.de with it-gnoth.de/phpinfo.php your will see the complete configuration. the string which is to be searched: href="index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97" the string which has to be find: article&id= below the php source code - both if version get the same result. It goes always in the else tree. Test script: --------------- function j2wp_change_single_url( $j2wp_post, $lnk_pos ) { global $CON, $wpdb; $j2wp_wp_tb_prefix = get_option('j2wp_wp_tb_prefix'); $j2wp_joomla_tb_prefix = get_option('j2wp_joomla_tb_prefix'); $permalink = false; // $lnk_pos ---> pos at href=" string in post_content // $post_lnk_end ---> pos at last " in link string of post_content // $post_lnk_string ---> contains the whole link string inkl. " at the end $post_lnk_end = strpos( $j2wp_post['post_content'], '"', $lnk_pos + 7); $post_lnk_string = substr( $j2wp_post['post_content'], $lnk_pos, $post_lnk_end - $lnk_pos + 1 ); if ( !(strrpos( $post_lnk_string, '/') === false) ) $pos_lnk_last_slash = strrpos( $post_lnk_string, '/'); // urls with structure: index.php?option=com_content&view=article&id=9257:2009-fha-loan-limits&catid=52:fha&Itemid=97 // if ( !(strpos( $post_lnk_string, 'article&id=') === false) ) if ( $pos_article_id = strpos( $post_lnk_string, 'article&id=') ) { $pos_article_id += 11; $article_id = j2wp_extract_number( substr( $post_lnk_string, $pos_srticle_id ) ); $url_post_id = j2wp_get_post_url_for_id( $article_id ); $permalink = get_permalink( $url_post_id ); } else { ...... -- Edit bug report at http://bugs.php.net/bug.php?id=52198&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52198&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52198&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52198&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52198&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52198&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52198&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52198&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52198&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52198&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52198&r=support Expected behavior: http://bugs.php.net/fix.php?id=52198&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52198&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52198&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52198&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52198&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52198&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52198&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52198&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52198&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52198&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52198&r=mysqlcfg
