uopz_allow_exit

(PECL uopz 5)

uopz_allow_exitAllows control over disabled exit opcode

Description

void uopz_allow_exit ( bool $allow )

By default uopz disables the exit opcode, so exit() calls are practically ignored. uopz_allow_exit() allows to control this behavior.

Parameters

allow

Whether to allow the execution of exit opcodes or not.

Return Values

No value is returned.

Examples

Example #1 uopz_allow_exit() example

exit(1);
echo 
1;
uopz_allow_exit(true);
exit(
2);
echo 
2;
?>

Notes

Caution

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.

Warning

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.
