Allows control over disabled exit opcode

uopz_allow_exit

(PECL uopz 5, PECL uopz 6)

uopz_allow_exit — Allows control over disabled exit opcode

说明

uopz_allow_exit ( bool $allow ) : void

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

参数

allow: Whether to allow the execution of exit opcodes or not.

返回值

没有返回值。

范例

Example #1 uopz_allow_exit() example

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

注释

Caution

OPcache optimizes away dead code after unconditional exit.
