Bug #15791 Updated: set_error_handler() can not be used to set error control to a class function

ID: 15791 Updated by: cox@php.net Reported By: ned@wgtech.com -Status: Analyzed +Status: Duplicate Bug Type: Feature/Change Request Operating System: All PHP Version: 4.1.1 New Comment: http://bugs.php.net/bug.php?id=9155 Previous Comments: ------------------------------------------------------------------------ [2002-02-28 17:38:35] mfischer@php.net This request is valid (it's a limitation of the current implementation in zend_builtin_functions.c) but your analysis wasn't very accurat. Methods of Static Classes or objects are normally passed with the syntax array($obj, 'method'); or array('class', 'method'); Anyway, it's an open feature request. ------------------------------------------------------------------------ [2002-02-28 14:26:17] ned@wgtech.com Heres the long and short of it: set_error_handler() wants a string as the name of the function that will handle errors. However, if you create a class and try to assign error handling to a function within the class, there is no way to reference that function. For example class ApplicationObject { var $error_List as array(); function ApplicationObject() { set_error_handler('trapError'); } function trapError($err_no, $err_str, $err_file, $err_line, $err_context) { echo "Trap error caught error ".$err_no; } } // *** Now create the object *** $app = new ApplicationObject(); trigger_error ("Cannot divide by zero", E_USER_ERROR); This doesn't work. Nor does changing set_error_handler('trapError') to set_error_handler('$this->trapError'). Removing the quotes just executes the function. Removing the assignment of error handling outside of the class like so: $app = new ApplicationObject(); set_error_handler('$app->trapError'); trigger_error ("Cannot divide by zero", E_USER_ERROR); Since the error handling function will need access to $error_List and I sure dont want to GLOBAL it, this kind of makes things difficult. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15791&edit=1
