View Source? Not with PHP
Tuesday February 6, 2007
Like many other languages, PHP is executed server side so your code never actually gets to the user's browser. Instead, the results of your PHP are sent to the user's browser. For this reason, if you try to view the source from your browser, or if you try to save the file from your browser, it just won't work. The browser never actually gets any PHP code.


And also the earth is revolving around the sun.
