	      $stack->push(1);

	      // This should succeed
	      $result = $stack->pop();
	      $ex = java_last_exception_get();
	      if (!$ex) {
		echo "$result
";
	      }

	      // This should fail (error suppressed by @)
	      $result = @$stack->pop();
	      $ex = java_last_exception_get();
	      if ($ex) {

SET_EXCEPTION_HANDLER(3)						 1						  SET_EXCEPTION_HANDLER(3)

set_exception_handler - Sets a user-defined exception handler function

SYNOPSIS

       callable set_exception_handler (callable  $exception_handler)

DESCRIPTION

	Sets  the  default exception handler if an exception is not caught within a try/catch block. Execution will stop after the $exception_han-
       dler is called.

PARAMETERS

	      o $exception_handler
		- Name of the function to be called when an uncaught exception occurs. This handler function needs to accept one parameter,  which
		will be the exception object that was thrown. This is the handler signature:
		void handler (Exception  $ex) NULL may be passed instead, to reset this handler to its default state.

	      Caution

		      Note  that  providing  an  explicit  Exception  type  hint for the $ex parameter in your callback will cause issues with the
		     changed exception hierarchy in PHP 7.

RETURN VALUES

	Returns the name of the previously defined exception handler, or NULL on error. If no previous handler was defined, NULL is also returned.
