#38504 [NEW]: class_exists strange behaviour

From: kn1g at yahoo dot com dot br Operating system: Linux PHP version: 4.4.4 PHP Bug Type: Class/Object related Bug description: class_exists strange behaviour Description: ------------ class_exists with return appears to avoid setting a variable after a class definition. Avoiding the return inside the if block like work as expected: <? if(!class_exists('newclass')){ class newclass(){ } } $var_newclass = "newclass ok\n"; ?> But I couldn't find anything in the documentation explaining this behaviour. Reproduce code: --------------- "class.php" <? if(class_exists('newclass')){ return; } class newclass{ function newclass(){ echo "hi\n"; } } $var_newclass = "newclass ok\n"; ?> "test.php" <? include("class.php"); new newclass; echo $var_newclass; ?> Expected result: ---------------- hi newclass ok Actual result: -------------- hi -- Edit bug report at http://bugs.php.net/?id=38504&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38504&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38504&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38504&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38504&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38504&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38504&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38504&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38504&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38504&r=support Expected behavior: http://bugs.php.net/fix.php?id=38504&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38504&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38504&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38504&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38504&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38504&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38504&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38504&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38504&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38504&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38504&r=mysqlcfg
