text split

ACI

Straight To the point:

I have a code to get the referrer of a website, that website has a bit in the url which i need to capture like (http://example.com/?bg=colour). so is there something that i can extract only the "colour" bit.

Note. Colour is a variable, it could be blue, black, green etc.

i can do it in flash (not really me, a while ago someone on another forum gave this):

var queryS:String = urlS.substring(urlS.indexOf("?")+1);

var queryA:Array = queryS.split("=");

thanks in advance

[man]parse_url/man will let you extract the 'query' part of the URL, and [man]parse_str/man should let you extract the pieces of the query string as variables (e.g. using the second parameter of parse_str(), you'd be able to use something like $url['bg'] to get the value 'colour').

im kind of a newbie, do you have an example code for this?

Just to make sure: if this is the URL that was used to access the page, then all you would need is the $_GET['bg'] array element. If it's coming from somewhere else:

// assume $urlString has the URL of interest
parse_str(parse_url($urlString), $parts);
if(isset($parts['bg'])) {
   echo $parts['bg'];
} else {
   echo "Oops!";
}
