PHP exception handling technology, top exception handler PHP custom exception C # exception handling Java exception

PHP handles exceptions like Java, with Try{}catch () {}

The function used to define the top-level exception handler is

Set_exception_handler ("My_exception");

The my_expection here is a developer-defined exception handler, a top-level exception processor that handles exceptions only if there are no functions in the program to handle exceptions, and if the top-level exception handler is not defined, the system defaults the exception handler to handle the exception

To illustrate:

 
  PHP    set_exception_handler("my_expection");     function my_expection () {        echo "Here is the top exception handler"    ;    } Try {        Nohello ("Hello");    } Catch　　(Exception$e) {        throw$e;    }  function Nohello ($nohello) {         if($nohello = = " Hello ") {        　　thrownewException(" Cannot enter Hello ");    }　　 Else {            echo "input succeeded";        }    }? >
