set_exception_handler

(PHP 5)

set_exception_handler Sets a user-defined exception handler function

说明

callback 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.

参数

exception_handler

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.

返回值

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