#43825 [NEW]: Suggestion for new "substring exists" function

From: anon at example dot com Operating system: PHP version: 5.2.5 PHP Bug Type: Feature/Change Request Bug description: Suggestion for new "substring exists" function Description: ------------ What we often need to test for is just whether a substring exists or not. For example this is very common in examining a user agent. Currently you can use strpos, but you have to be careful to test only with two specific formulations, using the strict equivalency operators: if (strpos($x, $y) === FALSE) or if (strpos($x, $y) !== FALSE) That "anti-FALSE" approach is generally awkward, and if you use == or != by mistake you'll have ambiguity with a substring position of number 0. It would be handy and much less prone to syntax mistakes, to have a dedicated "string exists" function which returns only TRUE or FALSE. This might be "strex" or "strpres" ("string present"). Plus an equivalent case sensitive version -- striex or stripres. -- Edit bug report at http://bugs.php.net/?id=43825&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43825&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43825&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43825&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43825&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43825&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43825&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43825&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43825&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43825&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43825&r=support Expected behavior: http://bugs.php.net/fix.php?id=43825&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43825&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43825&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43825&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43825&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43825&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43825&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43825&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43825&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43825&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43825&r=mysqlcfg
