Hello everyone!
I've got the problem with string replace,
i've got a string like:
/adsf/sdfd34/sdf/435ff/sdfdf
and i need to delete the last characters before "/", so it would
become:
/adsf/sdfd34/sdf/435ff/
I am trying to make a file manager of a sort, and need to make a link
"UP", which would take the user up one level in a directory...
I tried to use str_replace, seems its not the one,
thn i tried to use preg_replace, seems it is the one i need, but i'm
nowhere
near there...
Thats my last effort:
$output = preg_replace("/(\/*$)/","/", $input);
Could someone help me please?
Thank you very much! 7 2764

There is a nice function in the PHP function, section Filesystem, called
dirname. Look at <http://www.php.net/manual/en/function.dirnam e.php>

There is a nice function called dirname in the PHP toolbox, under the
section Filsystem. It could repond to your needs.
See <http://www.php.net/manual/en/function.dirnam e.php>

I'm unclear why a simple "<a href="../"> won't work, instead of trying to
compute what the reference should be.

Why not combine substr() and strrpos()? http://www.php.net/substr http://www.php.net/strrpos
$output = substr($input, 0, strrpos($input, '/'));
when $input is '/one/two'
strrpos($input, '/') will give the position of the last '/' in it (4 in
this case); substr() will return '/one'
Verify whether you need the last character to be a '/' and modify that
line accordingly.
Don't forget to check for inputs without '/'s.

using mod_rewrite may be one good reason...

Dirname does exactly what i need (never heard of it before, i
definately must get a book! :()
And combining substr and strrpos is a great way too!
Thanks a lot!
