#42129 [NEW]: restrict explode's function return type

From: david dot nqd at gmail dot com Operating system: Irrelevant PHP version: 5.2.3 PHP Bug Type: Feature/Change Request Bug description: restrict explode's function return type Description: ------------ This is not a bug report like #38337. Shouldn't the return type of explode be restricted to an array given valid inputs (strings)? This would mean that if an empty string was passed as the delimiter, the return would be an array containing individual characters. I doubt this would break any existing code unless people used explode to check that the delimiter === '' Reproduce code: --------------- <?php $x = explode('', 'abc'); ?> Expected result: ---------------- $x = array('a','b','c') Actual result: -------------- $x = false -- Edit bug report at http://bugs.php.net/?id=42129&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42129&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42129&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42129&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42129&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42129&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42129&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42129&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42129&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42129&r=support Expected behavior: http://bugs.php.net/fix.php?id=42129&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42129&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42129&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42129&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42129&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42129&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42129&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42129&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42129&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42129&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42129&r=mysqlcfg
