Regex for detect specified url

Question

I want to filter url's like bartender/profili/20/friends using preg_match.

Regex:

/^\/bartender\/profili\/d+\/friends/

Unfortunately it doesn't work.

Could somebody help?

Do you want to capture the \d+? If so, enclose them in ( ), that should fix it. Also, if you're regex uses /, I'd suggest using a different delimiter, less escaping that way:

<?php
preg_match( 
    '~^/bartender/profili/(\d+)/friends~', 
    '/bartender/profili/20/friends', 
    $matches 
);

var_dump( $matches );

Addendum: and - like everyone already mentioned - you indeed forgot the \ in front of the d+, but that was easy to overlook if you have to escape every / ;)

You have a slash in front of d+ (and have selected a badly readable delimiter for this situation). Try this:

#^\/bartender\/profili\/\d+\/friends#

I think you don't need to escape forward slash if you use # as a delimiter. No?

@genesis; no, he didn't, please read more carefully before a downvote. Upvoting the answer.

@genesis, you are wrong. Look carefully. I have added an extra backslash before d+

"bartender\/profili\/[0-9]+\/friends" also works. Here's an excellent resource for trying regular expressions: http://www.regextester.com/

You do not have to escape forward slashes, but you need to escape meta-characters (like 'd' for decimal digits)

^/bartender/profili/\d+/friends/

If / is your delimiter you do have to escape the forward slashes. You ignored the delimiters altogether it seems.
