php preg_replace字符串，以斜杠字符结束并结束

Question

dirname($_SERVER['PHP_SELF'])

returns in my case : /blabla/test

I am trying a preg_replace so to remove /blabla/.

I do this :

$dossier = preg_replace('/^\/[0-9a_z]\/$/','',dirname($_SERVER['PHP_SELF']));

what I hoped to be doing was : "find anything that starts with / and ends with / and has 0-9a-z in between. But this is not how to do this.

Thanks

Putting that dollar sign in there is throwing off the regex. I believe this is what you're looking for. Let me know if that doesn't work.

$dossier = preg_replace('/^\/[0-9a-z]*\//', '', dirname($_SERVER('PHP_SELF']));
