Req #67334 [NEW]: I can change the constant value using define method.

From: gangadhar dot kasim at gmail dot com Operating system: Windows PHP version: 5.4.28 Package: *General Issues Bug Type: Feature/Change Request Bug description:I can change the constant value using define method. Description: ------------ If I pass the optional third parameter in DEFINE method as TRUE, it is allowing me to override the existing value of a constant. This is not the expected behavior as constant's value should not be changed once it is declared. Test script: --------------- define("GREETING", "Hello you.",true); echo GREETING; // outputs "Hello you." echo "before changing the constant value <br/>"; //before changing the constant value define("GREETING", "sample value."); echo GREETING; // outputs "sample value." echo "<br/>"; Expected result: ---------------- constant's value should not be changed once it is declared. Actual result: -------------- it is allowing me to override the existing value of a constant. -- Edit bug report at https://bugs.php.net/bug.php?id=67334&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=67334&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=67334&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=67334&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=67334&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=67334&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=67334&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=67334&r=needscript Try newer version: https://bugs.php.net/fix.php?id=67334&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=67334&r=support Expected behavior: https://bugs.php.net/fix.php?id=67334&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=67334&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=67334&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=67334&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=67334&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=67334&r=dst IIS Stability: https://bugs.php.net/fix.php?id=67334&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=67334&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=67334&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=67334&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=67334&r=mysqlcfg
