PHP 7.4.0RC4 Released!

LuaSandbox::setCPULimit

(PECL luasandbox >= 1.0.0)

LuaSandbox::setCPULimitSet the CPU time limit for the Lua environment

Açıklama

public LuaSandbox::setCPULimit ( float|bool $limit ) : void

Sets the CPU time limit for the Lua environment.

If the total user and system time used by the environment after the call to this method exceeds this limit, a LuaSandboxTimeoutError exception is thrown.

Time used in PHP callbacks is included in the limit.

Setting the time limit from a callback while Lua is running causes the timer to be reset, or started if it was not already running.

Bilginize:

On Windows, the CPU limit will be ignored. On operating systems that do not support CLOCK_THREAD_CPUTIME_ID, such as FreeBSD and Mac OS X, wall-clock time rather than CPU time will be limited.

Değiştirgeler

limit

Limit as a float in seconds, or false for no limit.
