RE: [PHP] how to make javascript variable global?

The problem is that you're not sending the "starttime" with your form. That is why it doesn't know the starttime. Essenatially, when the user click on the submit button it treats this as a new request even if you're submitting to the same page. To accomplish what you want to do, it might be easier IMHO to do this: 1) Do nothing in the first page. 2) Once the submission is received on the 2nd page, at the start you start the counter ie get the current time 3) Once your processing in the 2nd script is finished, you get the current time 4) subtract the finish time from the start and display, either with jscript alert() or just a simple output to browser. > > Hi PHP (and JavaScript) gurus, > > I am trying to use JavaScript to get the execution time of a PHP script. > Specifically: a gettime() function is defined in the HTML <HEAD> part, and > to when the user clicks 'submit' button the then time in milisecond is > assigned to variable start, and after the requested page is returned and > loaded, JavaScript will get the current time in milisecond again, this time > assigns it to variable finish, so I will be able to subtract the two to get > the execution time. > > My question is: it seems the var start can not be available for comparison > when it is later called to compare with var finish.
