(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

返回值
没有返回值。
范例
Example #1 uopz_allow_exit() example
<?phpexit(1);echo 1;uopz_allow_exit(true);exit(2);echo 2;?>
以上例程会输出：

注释
Caution OPcache optimizes away dead code after unconditional exit.
