每个PHP都需要单独的请求吗？

Question

I am trying to reduce the number of requests on my site (to improve page speed). In one file, I have 10 separate php require statements calling 10 different php files.

My question is, are these 10 require statements considered as 10 separate requests? By replacing the require statements with actual contents from the called php file can I reduce the number of requests?

I would greatly appreciate if someone could please clarify this form. Please note that I am not an experience programmer or web designer. Thanks!

Like my comment, it's depending how PHP is installed.

If you using PHP as Mod (mod_php), your Webserver create only one PHP process. All requests will be handled here.

But if you have implement PHP as an CGI-Wrapper, each request starts an PHP instance.

To perform your loading time, use Opcode-Caches like eAccelerator, APC or other for PHP Scripts. Other solution is to handle requests with the right way: Cache statical files like Stylesheets, Javascripts, Images,..

Edit

An other solution is: optimize your PHP scripts. A good inspector is New Relic, here you can see, what scripts have very large execution time. I had create an Blog post of New Relic with their features, but it's only in german: http://hovida-design.de/php-die-macht-der-performance/
