uopz_allow_exit

(PECL uopz 5, PECL uopz 6, PECL uopz 7)

uopz_allow_exitAllows 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。
