set_exception_handler()

set_exception_handler

(PHP 5)

set_exception_handler -- Sets a user-defined exception handler function

Описание

string set_exception_handler ( callback exception_handler )

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

The exception_handler 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.

Список параметров

exception_handler: Name of the function to be called when an uncaught exception occurs.

Возвращаемые значения

Returns the name of the previously defined exception handler, or FALSE on error. If no previous handler was defined, an empty string is returned.

Примеры

<?php
function exception_handler($exception) {
echo "Uncaught exception: " , $exception->getMessage(), "\n";
}

set_exception_handler('exception_handler');

throw new Exception('Uncaught Exception');
echo "Not Executed\n";
?>
