Hello again, I am wondering how to get a ref number from a url into a php variable. Is there a php function for this by chance?

Could you post an example?

If your URL looks like:
file.php?ref=090865

Just use:

PHP Code:

echo $_GET['ref']; 


this will echo the variable in the URL called 'ref'

nice!!!!! Thank you!

P.S. How popular is it to use PHP these days? It seems as though everybody is using Java, Javascript, etc. Does PHP still play a dominant role in server side code?

Javascript is not server side code, and the web manifestation of java is jsp, which is less popular than php. PHP is still very popular.

Well, glad to hear all of this learning will be of use in the future then!

BTW, is there a way to parse a string that is black space delimited in php?

completely agree. actually i believe php is going better and use area is going wider over time

you can do that using explode function
ex:

PHP Code:

$arr=explode(" ",$str);
//where $str is the string you need to parse
//$arr is a result array contain list of the extracted elements
