在Lampp中使用Runkit_Sandbox

Question

I want to use the sandboxing of the extension runkit . From README file

Sandboxing is ONLY AVAILABLE in PHP 5.1 (release version, or snapshot dated
after April 28th, 2005) when thread safety has been enabled.

The version of PHP in my lampp is 5.4.7 which should be OK but its Thread Safety is disabled. From phpinfo() we can see the runkit is installed but its Sandbox Support is disabled or unavailable. So when I try to use the Runkit_Sandbox class, an error came out

Fatal error: Class 'Runkit_Sandbox' not found 

I don't really what to do now.. Is it possible to use Runkit_Sandbox class in my lampp?

Answer 1

The master branch of http://github.com/zenovich/runkit is compatible with all versions of PHP. Sandboxing only works if thread safety is enabled. So you should recompile your PHP after configuring it with flag --enable-maintainer-zts to use Runkit_Sandbox class. After that you should use Runkit compiled from source.
