From: Operating system: Ubuntu 10.04 PHP version: Irrelevant Package: Strings related Bug Type: Feature/Change Request Bug description:Add in_string() function similar to in_array()
Description: ------------ It would be quite helpful to have a helper function in_string(), like in_array(), that checks if a substring is within some string. Sure, with strpos()/stripos(), this can be achieved, but not everyone understands that immediately (and the same could be said about in_array(), which can also be done quite simply with a foreach, but surely not everyone gets that). There's some code how that might work in PHP at MediaWiki http://svn.wikimedia.org/viewvc/mediawiki/trunk/phase3/includes/GlobalFunctions.p hp?view=markup which is open-source and could be used. Now it is the question if the third parameter should also be in PHP, but no matter which way, it would still probably not too difficult to create such a helper function. Test script: --------------- # MediaWiki's way of doing this function in_string( $needle, $str, $insensitive = false ) { $func = 'strpos'; if( $insensitive ) $func = 'stripos'; return $func( $str, $needle ) !== false; } # don't use (bool)$func($str, $needle) because it can be 0 (first character) -- Edit bug report at http://bugs.php.net/bug.php?id=53788&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53788&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53788&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53788&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53788&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53788&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53788&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53788&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53788&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53788&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53788&r=support Expected behavior: http://bugs.php.net/fix.php?id=53788&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53788&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53788&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53788&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53788&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53788&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53788&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53788&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53788&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53788&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53788&r=mysqlcfg
