(PECL uopz 5)
uopz_get_exit_status — Retrieve the last set exit status
Retrieves the last set exit status, i.e. the value passed to exit().
This function has no parameters.
This function returns the last exit status, or NULL if exit()
has not been called.
Example #1 uopz_get_exit_status() example
<?php
exit(123);
echo uopz_get_exit_status();?>
The above example will output:
123
OPcache optimizes away dead code after unconditional exit.
Note: Because this is a language construct and not a function, it cannot be called using variable functions.
This function is not (yet) binary safe!
Note: register_globals: important note
As of PHP 4.2.0, the default value for the PHP directive register_globals is off. The PHP community discourages developers from relying on this directive, and encourages the use of other means, such as the superglobals.
