Regex for detect specified url

I want to filter url's like bartender/开发者_如何学Pythonprofili/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#

you forgot to escape \d+

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

You are missing a backslash before d+: \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/
