Question

I have a url of the format /?var1 = val1&var2 = val2;

I want to check for the presence of just var2 = val2 in the url using php. How can that be done?

You can use the $_GET superglobal

if(!empty($_GET['var2']) && $_GET['var2'] == 'val2')) // do something

do this

if (isset($_GET['var2']))  // check if exist
{ 
  if ($_GET['var2'] == val2) // do something
}

Or, combined if (isset($_GET['var2']) && $_GET['var2'] == val2). Due to short-circuiting.

If this is not the QUERY_STRING for the request (in which case you should just use $_GET as @Spechal said), you can use parse_str(). It "uses the same mechanism that PHP uses to populate the $_GET, $_POST, etc. variables."
