How to measure requests per user and minute

Question

At first I want to say that request doesn't mean ' mysql query '

So what request mean? I answer to it on example.

• I have ajax script, that refers to php page.
• Script send some data, also user id who request this page.
• This php do something code.

Question:

How many times in a one minute, every user request this php page? How to measure it in high performance?

Answer 1

At the beginning of your php scripts you can retrieve info about the request from the $_SERVER global variable. If you var_dump the $_SERVER variable you can see what information is available about the request. I imagine that something like $_SERVER['REQUEST_URI'] or $_SERVER['SCRIPT_FILENAME'] will hold the info that you need. Store that info plus the user id and the date in a mysql table and you should be set?
