ereg() to preg_match() how?

Question

I have kind of simple regexes that i am using.

It's so simple as:

"user/"
"user/[A-z0-9_-]"

These all work fine with ereg, but not preg.

How to convert it?

Thanks

It's most probably because your're missing the delimiters. Try this:

"~user/~"
"~user/[A-z0-9_-]~"

What is the point of delimiters? It seems like all the posix regexes works enclosed with those delimiters. To they add functionality or are they syntactic sugar? – Lars Hansen Mar 10 '11 at 18:29

Delimiters makes it possible to add modifiers. You can read more about it at http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php – alexn Mar 10 '11 at 18:52

ereg('jpg$', $query)

Turns into:

preg_match('@jpg$@', $query)
