Is this application written in php or not?

Some sites use mod-rewrite or change .php extensions to .html extensions with .htaccess to hide the information that the application is written with php.

But it’s really easy to find out if it’s written with php, because there is an Easter egg in php. If you send a special string to any php site, the browser generates a php logo or a dog as image.

    …. That’s true unless you do change it before session_start call:

    string session_name ([ string $name ] )
