now this above youtube URL pass it to my domain page ...it will proceed for downloading


now my question is

How it is possible to get this target ? because i have no idea user just replace domain name ... http://www.youtubedownload.com/watch?v=Ge41tbymZC8 but php page will understand target URL is

and proceed further action .

 

No body have idea ?

 

rewriterule for ^watch$ -> index.php?v=$1

sanitize $_GET['v'].

 

Link to get the SWF video: 'http://www.youtube.com/v/' . $_GET['v']
(add whatever validation you need...)

Not sure if that's what you look for

 

don't you mean? -> ^/watch\?=([a-zA-Z0-9]+)$ -> index.php?v=$1

 

you will have to grab flv/vid link from youtube using php
