You can use a regular expression to capture the part of the url you need.

preg_match('#journal/[a-zA-Z0-9]+\-([a-zA-Z0-9]+)/#', $string, $matches);
$match = $matches[1];

are u talking about GET parameters? If so, u can retrieve it from php as

$variable = $_GET['v'];

if u are trying to extract this from a random url, u will have to do some string manipulations... google for php string functions...

Although you could use regex it would be better to use the following:

$url='http://www.youtube.com/watch?v=NMAYr709-9Y&feature=dir';
$var=explode('?v=',$url);
$var=explode('&',$var[1]);
echo $var[0];
