PHP是线程安全的吗? [英] Is PHP thread-safe?

问题描述

• Linux(从5.2版开始)在Linux/UNIX上是线程安全的吗?
• 是否可以将其与Apache Worker-MPM或Event-MPM一起使用?

• Is PHP (as of 5.2) thread-safe on Linux/UNIX?
• Would it be possible to use it with Apache Worker-MPM or Event-MPM?

我到目前为止收集的事实尚无定论:

The facts I gathered so far are inconclusive:

• 大多数发行版中包含的默认二进制文件均已禁用ZTS，因此我知道我必须重新编译它们.
• 从理论上讲，启用ZTS的Zend Engine(核心PHP)是线程安全的.
• 有人说某些模块可能不是线程安全的，但我还没有找到任何存在或不存在的模块列表.
• PHP FAQ 的说明几乎相同如上所述.

• Default binaries included in most distributions have ZTS disabled, so I'm aware, that I'd have to recompile them.
• In theory Zend Engine (core PHP) with ZTS enabled is thread-safe.
• It's said that some modules might not be thread-safe, but I haven't found any list of modules that are or that are not.
• PHP FAQ states pretty much same as above.

您的经历是什么?

这不仅与分段错误(Windows命名法中的访问冲突")有关. 线程安全还有很多.

It's not only about segmentation faults ("access violations" in Windows nomenclature). There is a lot more to thread safety.

推荐答案

我知道gettext和 set_locale 不是线程安全的. PHP不应与线程MPM一起使用.

I know gettext and set_locale is not threadsafe. PHP should not be used with a threaded MPM.

PHP不是线程-安全了.
正在运行未运行PHP的.
