Re: [PHP] what will be the output for this pgm?
Of course there will not be any output. That's because when you type in the directly type the url in the browser there will not be any referer. Try putting a link from another domain to that page and you will get some output then / try visiting the page through a search engine. i.e make the page come up in you search results and then click on it and when you visit the page it will show you the domain of the search engine.

For me it is printing the blank value. That's what I'd expect, if you're running that script directly. The referrer variable generally only gets a value if you reached the script by clicking on a link. --- Mark Roedel | Blessed is he who has learned to laugh Systems Programmer | at himself, for he shall never cease LeTourneau University | to be entertained.
