Reproduce code: --------------- <?php class foo {} define('MYCLASS', 'foo'); $f = new MYCLASS(); # Won't work $f = new $_CONSTANTS['MYCLASS'](); # Won't work $s = MYCLASS; $f = new $s(); # Works ?> Expected result: ---------------- These way of instanciating the foo class should all work. Actual result: -------------- The two first syntax produce the same result: Fatal error: Class name must be a valid object or a string -- Edit bug report at http://bugs.php.net/?id=42441&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42441&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42441&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42441&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42441&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42441&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42441&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42441&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42441&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42441&r=support Expected behavior: http://bugs.php.net/fix.php?id=42441&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42441&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42441&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42441&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42441&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42441&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42441&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42441&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42441&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42441&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42441&r=mysqlcfg
