set_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_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.

Parameters

Return Values

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