# set_exception_handler

(PHP 5)

set_exception_handler — Sets a user-defined exception handler function

### 설명

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.

### 인수

`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.

### 반환값

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

### 예제
