正则表达式没有返回true

Question

I'm struggling to convert .htaccess rule into PHP regex if statement, here's the rule as it is in htaccess

RewriteRule ^user/([a-zA-Z0-9-]+)$ user.php?slug=$1 [L]

Now for PHP I've tried several ways, as i'm not too good with REGEX nothing seems to work.

if(preg_match("#user\/(a-z_\-0-9)\$#",$request)) {
        exit("okKKKKKK");
    } else {
        exit("no");
    }

$request is "/user/test-user" anyone could give me a hand?

Answer 1

That is not correct translation. Use this equivalent preg_match regex:

preg_match("#^/user/([a-zA-Z0-9-]+)$#", $request);

Remember rewrite rules in .htaccess have missing leading slash as .htaccess is per directory directive.
