note 83368 deleted from function.restore-error-handler by googleguy

Note Submitter: sebagr gmail com ---- I think what Isole wanted to say is that if you push the same error handler twice, then you'll need to call restore_error_handler() twice if you want to get rid of it: <?php function custom_error_handler(){ echo 'My error handler'; return false; } set_error_handler('custom_error_handler'); // Stack is: <default error handler> | custom_error_handler set_error_handler('custom_error_handler'); // Stack is: <default error handler> | custom_error_handler | custom_error_handler trigger_error('error', E_USER_WARNING); // Will print 'My error handler'; restore_error_handler(); // The stack is <default error handler> | custom_error_handler trigger_error('error', E_USER_WARNING); // Will still print 'My error handler', since the stack is still dirty with our first custom_error_handler. restore_error_handler(); // The stack is <default error handler> trigger_error('error', E_USER_WARNING); // Now this will trigger the default error handler. ?>
