A simple PHP CSP reporter script that saves violations to disk.
Put the csp-reporter.php on your web server, or in your local directory were you have your website PHP files, and specify csp-reporter.php in your CSP report-uri directive (ref. 7.13).
Note: CSPv3 is still in its draft, therefore, CSPv2 will continue to work and there will most likely be backward compatibility.
