PHP: Detect Page Refresh

Question

I have a page action.php on which I run an SQL query through the code, so that whenever the page is viewed the query runs like its like counting page vi

Answer 1

i have solved the problem ... HURRAHHH with no session & no cookies

the solution is a combination of PHP : AJAX : JavaScript

the query that you want to run on Page Load & not on page Refresh run it as via AJAX call lets say my function for doing that is

function runQUERY()
{
    xmlhttp=new XMLHttpRequest();
    xmlhttp.open("POST","doIT.php",false);
    xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
    xmlhttp.send();
}

and i can simply check with Javascript that the page is a fresh load or its a refresh by doing the following

and in your doIT.php simple add your PHP code which you were going to put in the normal page
