I'm looking to keep track of how many times a form is submitted as well as using that number to be called back into another php file. I've written this but it's not working. The text file number contains a "0" I want it to increase each time.
Code:
<?php
$num = "number.txt";
$increase = fopen($num, 'w');
$val = ($num + 1);
fwrite($increase, $val);
fclose($increase);
?>
I'm putting this in here instead of php because I don't know if this is the best script or code to keep track of the number of times its clicked. Any Ideas? Thanks.
