title: PHP function for getting file size and loading time for a page
body: <p>Similar to my last question, I'd like to have a PHP function that can take a local path and tell me (a) how much the total file size is for HTML, CSS, JS and images, and (b) the total load time for this page.  Like YSlow I think, but as a PHP function.</p>
  
  <p>Any thoughts?  I looked around and was wondering can I use CURL for this?  Even though I need to check paths that are on my own server? thanks!</p>
  
  <p>Update:</p>
  
  <p>After reading the comments, realizing I'm off base. Instead wondering is there a way programatically get a YSlow score for a page (or similar performance score). I assume it would need to hit a third-party site that would act as the client. I'm basically trying to loop through a group of pages and get some sort of performance metric. Thanks!</p>
