Description
void
register_shutdown_function ( callback function)
Registers the function named by function to be
executed when script processing is complete.
Multiple calls to register_shutdown_function() can be
made, and each will be called in the same order as they were registered.
If you call exit() within one registered shutdown
function, processing will stop completely and no other registered
shutdown functions will be called.
The registered shutdown functions are called after the request has been
completed (including sending any output buffers), so it is not possible
to send output to the browser using echo() or
print(), or retrieve the contents of any output
buffers using ob_get_contents().
Note:
Typically undefined functions cause fatal errors in PHP, but when the
function called with
register_shutdown_function() is undefined, an error
of level E_WARNING is generated instead. Also,
for reasons internal to PHP, this error will refer to
Unknown() at line #0.
See also auto_append_file,
exit(), and the section on
connection handling.
