PHP Regular Expression match anything except forward slash

Question

I'm going to have 2 different sets of URLS

/marketplace/producer/123-producer-name
/marketplace/producer/123-producer-name/5-genre/500-max-price/0-added/newest/1-page

I know the regular expression for the second, but for the first one i'm finding it tricky. I'm trying to match the expression, but I want to make sure it doesn't match the second one as well. I'm using the following;

/\/marketplace\/producer\/([0-9]+)\-[^\/]/

My logic at the end being match every character except a forward slash, which would then mean it's s possible match for the second one. But when I test it, it returns true even with a forward slash. What am I doing wrong?

I'd recommend using something like a hash at the start and end of your regexp so it's easier to read: #\/mark....-[^\/]# — Seer

@Seer Wouldn't you mean #/mark....\-[^/]# as the modifier was changed (hence you wouldn't have to escape slashes?) — h2ooooooo

Do it like this:

/^\/marketplace\/producer\/([0-9]+)-[^\/]+$/

Your regex searches for a string starting with a / followed by marketplace/producer/ followed by 1 or more digits followed by a - followed by one or more characters which is not a / and ends there.

I think the problem was with that there was no anchoring character and it matched a substring of the input also. Also you missed the + which makes the regex engine look for a single non-forwardslash character.

Yeah i'm using that exact one and it returns true with and without a forward slash at the end

@Wasim You want to match /marketplace/producer/123-producer-name and don't match /marketplace/producer/123-producer-name/5-genre/500-max-price/0-added/newest/1-page, right?

Ah actually it does work. It returns true when the URL is /marketplace/producer/123-pro or /marketplace/producer/123-pro/ but returns false if anything comes after the last forward slash. This is exactly how I want it. Many thanks for your help

@Wasim Was it what you wanted?

@NaveedS yes I wanted to match /marketplace/producer/123-pro and /marketplace/producer/123-pro/ but nothing else unless it's /marketplace/producer/123-producer-name/5-genre/500-max-price/0-added/newest/1-‌page

Simply use this regular expression [^/]+$. It will match everything after last forward slash.
