| + | ==== MPM Prefork vs Worker ==== | ||
| + | |||
| + | A propos de MPM prefork vs worker il y a bien des soucis avec php qui serait parfois "non thread-safe", | ||
| + | from: http:// | ||
| + | |||
| + | "Since with mod_php, PHP gets loaded right into Apache, if Apache is going to handle concurrency using its Worker MPM (that is, using Threads) then PHP must be able to operate within this same multi-threaded environment -- meaning, PHP has to be thread-safe to be able to play ball correctly with Apache! | ||
| + | |||
| + | At this point, you should be thinking "Ok, so if I'm using a multi-threaded web server and I'm going to embed PHP right into it, then I must use the thread-safe version of PHP". And this would be correct thinking. However, as it happens, PHP's thread-safety is highly disputed. It's a use-if-you-really-really-know-what-you-are-doing ground." | ||
