No ending delimiter '/' found error

Question

I have adjusted a small script to check backlinks. Yet I keep on getting the error

Warning: preg_match() [function.preg-match]: No ending delimiter \'/\' found in li

Answer 1

The error is very clear really, you didn't include the trailing /:

preg_match('/
About \(.*?)\ /',$v,$s);

I honestly doubt your escape characters are well placed though. Maybe you meant \)?
