see php code

I wish I could do that,
but I can only use the browser.

Do you mean that you don't have access to the server/php files?
You can only display the php-files if you have access to the server. It's not that you can view a php-file of a random website that is running php.
That would be a big security leak ;)

When a browser (called a "client") makes a request for a page from a server (called a "server") the server prepares a response string including headers and browser output.  Browsers use HTML to mark up and format the data from the server.  PHP scripts generate this HTML on the server, and then the server sends the HTML to the client machine.  The PHP code is never sent, just the HTML statements it generates.

But good news: http://www.cmsmadesimple.org/ is open source, so you can grab a copy and install it on your local machine.  Then you can see the PHP code.

My own IDE goes like this.  I use TextPad or NotePad++ to write PHP code.  When I am ready to test, I upload the PHP code to a URL on my server using an FTP client.  Then I visit the URL and see what the PHP code creates.  I do not need to see the PHP code on the server because I have a copy of it in front of me on my machine.

May not be a security risk because i am Given browser admin access to files and filemanager. Could I download the php files and view them on my computer.

one answer is to create a browser script another answer is to just use ftp.
both work, thanks
