how to identify if PHP is using VC6 or VC9 and wheather its threaded safe or non threaded safe?
<p>I am trying to download an extension for this I need to know my installation uses VC6 or VC9?  And whether it is threaded safe or non threaded safe. PHP version I am using is 5.3.5. I did look into the phpinfo result page,  I see one reference regarding it as: <code>MSVC6 (Visual C++ 6.0)</code> </p>

<p>Does this mean my php installation uses VC6? How will I come to know about threaded safe Vs non threaded safe?</p>
