I've been using PHP-5.4.3 for about a month now, and today, I decided to make a switch to PHP-5.5.5, I downloaded the source code, and placed it in C:/php (also renaming the folder php-5.5.5 to php) and I added server variables, as usual C:/php/ <-- but here I got stuck. Because, usually I appended the php.exe at the end, which was found inside the PHP folder so, I could be able to access PHP from the command line, or start the built-in server, but now, I can't find this file, and I can't find a way to start the server from the command line either.

Anyone help.
