Req #60738 [NEW]: Allow 'set_error_handler' to handle NULL

From: Operating system: irrelivant PHP version: 5.3.9 Package: Unknown/Other Function Bug Type: Feature/Change Request Bug description:Allow 'set_error_handler' to handle NULL Description: ------------ Can the 'set_error_handler' function be made to accept NULL as the parameter in such a way as to reset this feature to the default state of -no- handler being set? This would duplicate the behavior of the 'set_exception_handler' function. Note: this change should not interfere with the 'restore_error_handler' function. And as for the 'set_exception_handler' function - if NULL is given as a parameter, can the return value of 'set_exception_handler' be set to the details of the previously set exception handler function (string or array) instead of always '(bool) true' as it now does? Test script: --------------- function testhandler1($errno= null, $errstr= null, $errfile= null, $errline = null) { error_log('1: ' . print_r(func_get_args(), true)); die(); } function testhandler2($errno= null, $errstr= null, $errfile= null, $errline = null) { error_log('2: ' . print_r(func_get_args(), true)); die(); } var_dump(set_error_handler('testhandler1')); var_dump(set_error_handler('testhandler2')); var_dump(set_error_handler(null)); Expected result: ---------------- NULL string(12) "testhandler1" string(12) "testhandler2" Actual result: -------------- On line 'var_dump(set_error_handler(null));', a 'set_error_handler() expects the argument () to be a valid callback' error is generated and handled by function "testhandler2" -- Edit bug report at https://bugs.php.net/bug.php?id=60738&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=60738&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=60738&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=60738&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=60738&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=60738&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=60738&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=60738&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=60738&r=needscript Try newer version: https://bugs.php.net/fix.php?id=60738&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=60738&r=support Expected behavior: https://bugs.php.net/fix.php?id=60738&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=60738&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=60738&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=60738&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=60738&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=60738&r=dst IIS Stability: https://bugs.php.net/fix.php?id=60738&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=60738&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=60738&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=60738&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=60738&r=mysqlcfg
