#39294 [NEW]: "Fatal error: Cannot redeclare class" for classes that use extends

From: a79315 at hotmail dot com Operating system: suse 10.1 PHP version: 5.1.6 PHP Bug Type: Class/Object related Bug description: "Fatal error: Cannot redeclare class" for classes that use extends Description: ------------ This code works fine on PHP 4 but fails on PHP 5.1.2. I know that I need to try it on the 5.1.6 version but I can't get my suse server to upgrade to it. On PHP 5.1.2 it reports "Fatal error: Cannot redeclare class". If the "extends CTest3" is removed from file test.inc there is no error. Reproduce code: --------------- File 1: test.php <? require "test2.inc"; require "test2.inc"; ?> File 2: test2.inc <? if (defined("CTEST2")) return; define("CTEST2", 1); require "test3.inc"; class CTest2 extends CTest3 { function CTest2() { print "Test2"; } } ?> File 3: “test3.inc” <? if (defined("CTEST3")) return; define("CTEST3", 1); class CTest3 { function CTest3() { print "Test3"; } } ?> Expected result: ---------------- No error Actual result: -------------- Fatal error: Cannot redeclare class ctest2 in test2.inc on line 16 -- Edit bug report at http://bugs.php.net/?id=39294&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39294&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39294&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39294&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39294&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39294&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39294&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39294&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39294&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39294&r=support Expected behavior: http://bugs.php.net/fix.php?id=39294&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39294&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39294&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39294&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39294&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39294&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39294&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39294&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39294&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39294&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39294&r=mysqlcfg
