From: jimmy at basicmatrix dot com Operating system: Linux PHP version: 5.2.9 PHP Bug Type: Scripting Engine problem Bug description: call_user_func_array returns NULL (instead of FALSE) for invalid callbacks Description: ------------ call_user_func_array() claims it "Returns the function result, or FALSE on error." My testing shows it returns NULL if the callback function is not a valid callback. Reproduce code: --------------- <?php function callable() { return 'Good.'; } $return = call_user_func_array('callable',array()); var_dump($return); $return = call_user_func_array('not_callable',array()); var_dump($return); ?> Expected result: ---------------- string(5) "Good." Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'not_callable' was given in _______ on line 9 FALSE Actual result: -------------- string(5) "Good." Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'not_callable' was given in _______ on line 9 NULL -- Edit bug report at http://bugs.php.net/?id=47554&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47554&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47554&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47554&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47554&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47554&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47554&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47554&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47554&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47554&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47554&r=support Expected behavior: http://bugs.php.net/fix.php?id=47554&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47554&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47554&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47554&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47554&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47554&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47554&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47554&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47554&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47554&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47554&r=mysqlcfg
