echo errors[e->getCode()].': '.e->getMessage().'在'.e->getFile(). '的第'.e->getLine().\行\\n\echo e->getMessage(); die(); } //

set_error_handler('error_handler'); //restore_error_handler();

set_exception_handler('exception_handler'); //restore_exception_handler();

我肯定是错误 ?>

执行结果：

notice: Use of undefined constant 我肯定是错误 - assumed '我肯定是错误'在E:\\web\\web\\php\\bi\\exception\\m.php的第74行 Use of undefined constant 我肯定是错误 - assumed '我肯定是错误'

另外,在类中,还可以这样:

function trigger_error(error_msg, error_type = E_USER_WARNING) {

trigger_error(\}

著名的Smarty就是这么做的.
