PHP函数用于获取页面的文件大小和加载时间

Question

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.

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!

Update:

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!

Answer 1

For the filesize.

• Create a loop to read all files in a specific directory with dir.
• Then for each file use filesize.

Loadtime Loadtime depends on the connection speed and the filesize. And I see that you specify that you are reading locally the files. You can detect how much time it take you to read those files but this will not be the loadtime for the page for an external user.
