Using regex pregmatch to read youtube video ID from url

[physaux]

Hey guys, I am trying to write some code to get the referring url to my page, and then do something unique accordingly. So here is my code so far:

$ref = getenv("HTTP_REFERER");
$goodvideoID = xxxxxxxxx //11 characters long

 

How can I check if the goodvideoID is in the ref url? I am trying with preg match but I keep getting errors...  :'(

you can use parse_url and then use parse_str

If all you want to know is whether $goodvideoID is contained in $ref you could use stristr.
