Best way to trim off some junk form my variable?

[jixor]

I have something like
'XXX/YYY/ZZZ/abc' or 'XXX/123' or etc
And I want to be left with only the characters after the last '/'. I'm not sure on the best way to do this. Thanks.

PS: Sorry for using 'trim' in subject but I couldnt think of a better word 😉

If that backslash is constant, you may want to use explode() or if the length is constant, maybe substr()

[jixor]

But if I use explode I get an array, then i have to select the last item, it would be preferable to not go that way.

[LordShryku]

Well, is it always going to be 3 characters?

[jixor]

no it will vary in length

BTW

I am currently using:

$HTTP_REFERER;
$refererurl = getenv('HTTP_REFERER');
$refererelements = explode("/", $refererurl);
$refererpage = end($refererelements);

Now that I thik about that it is ok, but I was just hoping for a function that would just trim everything before the last '/' like one line rather than two 😉

well there is a way 🙂
its strrchr($haystack,$needle)

so you can put this:

$refererpage = strrchr($refererurl,"/");

now $refererpage will display the: /file.php

if you want to get rid of the / then use this:

$refererpage = str_replace("/","",strrchr($refererurl,"/"));

which should display file.php

but, yes there is a but, if your using it for the current address/page that the user is looking at (btw this does include any extras like: file.php?this=that)

$refererpage = getenv("REQUEST_URI");

the code above also includes the / so you use this to get rid of the / use this:
$refererpage = str_replace("/","",getenv("REQUEST_URI"));
