php异常处理

function onError($errCode, $errMesg, $errFile, $errLine) {        
		echo "Error Occurred\n";        
		throw new Exception($errMesg);    
	}     
	function onException($e) {        
		echo $e->getMessage();    
	}     
	set_error_handler("onError");     
	set_exception_handler("onException"); 
	try {
		$mm=0/0;
		echo $mm;
	} catch (Exception $e) {
		echo $e->getCode()."\n";
		echo $e->getMessage()."\n";
	}


--------------------------------
一定要定义和调用
set_error_handler("onError");    
set_exception_handler("onException");
否则  进不去catch(){}里面去的
