PHP set_exception_handler() Function

Hello folks! welcome back to a new section of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP set_exception_handler() Function.

The PHP set_exception_handler() function is used to set the default exception handler if no exception is caught within a try/catch block. Execution will stop after exception handler is called.


Following below is the syntax to use this function -

string set_exception_handler ( callback $exception_handler );

Parameter Details

Sr.NoParameter & Description


Name of the function to be called when an uncaught exception occurs. This function must be defined before calling set_exception_handler(). This handler function needs to accept one parameter, which will be the exception object that was thrown.

Return Value

This built-in PHP function returns the name of the previously defined exception handler, or NULL on an error. If no previous handler was defined, then NULL is also returned.


Try out the below example -

   function exception_handler($exception) {
      echo "Uncaught exception is : " , $exception->getMessage(), "\n";
   throw new Exception('Not Found Exception');
   echo "not included Executed\n";


When the above code is executed, it will produce the following result -

Uncaught exception is: Not Found Exception
