Read:
http://uk2.php.net/manual/en/function.preg-match.php
And note how the examples form their expressions. They all start with
'/' and are terminated with a '/' optionally followed by a modifier
(such as 'i' which makes the match case insensitive).
To make your pattern work, use:
"/<a[^>]*>.*?<\/a>/"
Note that I've escaped the '/' in '</a>'
Technically, you can use anything as a start and finish marker for your
pattern, as long as it's the first thing that appears. You could avoid
escaping the '/' in </a> by using '|' as a delimiter. However, it seems
to have become common practice to use '/' these days, and that's what
most examples you'll see will use.
Hope that helps. Always remember to read the PHP manual -- it's excellent!
Mark
