PHP- How do I do this? (Regex)

[Bes]

Hi

In perl, I can write: (Syntax may not be 100% but you get the idea)

my $var=foobarbar;
$var=~m/foo(.*)ar^/;
print $0;

and get barb as the result. (Because I match the contents of var)

If i try and replicate this in PHP, it does not work (It seems to trip up because you cannot write things like $1 on new lines)

Is this really the case? How can I get around this?

Thanks

Thanks guys I did it a totally different way in the end:

$filename=filter_var(substr(strrchr($_SERVER["REQUEST_URI"], '/'), 1), FILTER_SANITIZE_STRING);
$querySeoName= substr($filename, 0, strpos ($filename, '.'));

Just a question.... $querySeoName (which starts life as $filename, which is part of the URL the user has entered/ been lined to) exists because I am splicing my own workflow into a cart with SEO optimisation, and in order to keep the two apps (My app and the cart) as seperate as possible to make upgrades less painful, I am using the last part of the URL ($queryseoname) to do a lookup in the cart's DB where it keeps a record of the SEO freindly names and corresponding product ID as I do not want to merge the two products together really. (My app and the cart share common product IDs). Now, obviously I need to stop people from being able to put naughty code in the URL bar which could lead to a hack... will (SANATIZE_STRING) be sufficient?

Thanks
