How can I solve this?

Hi everyone,



I am using PHP_SELF in order to get the current path on a dynamically
created webpage. This gives me the following:



/my_website/index.php



My problem is, ALL I NEED is the directory name - no / or no index.php, how
can I strip these out to leave JUST the folder name the file is located in?
I need this because the page is dynamically created, and it gets templated
information from a database and needs to use the foldername as the
identifier between the DB entry to use for grabbing the information and the
pages inside the directory.



Any help would be really appreciated and I'm certain it's something REALLY
obvious.



Chris

RE: How can I solve this?

Wonderful thank you, it displays a single / before the dir name but I can
remove that without too much trouble :-)

Thank you.

Re: How can I solve this?

Two alternatives..

dirname(); returns basically just the path, same string as using
pathinfo["dirname"] but saves that array step..

or back to the love of my life [well, the non-human one]:
preg_replace("/^\/?(.*)\/[\w]+\.php$/","$1",$PHP_SELF)

that strips that leading forward slash too ;-)



by love of my life I mean, Regular Expressions, not that particular one
:P

ciao

A friend of mine updated your regular expression... Check it out if your
interested.

Re: How can I solve this?

Thank you,


In fact, its called busy-ness, and I tend to believe I have quite a
prowess in the was of Regular Expressions.


Reason I have the character class? You betchya! So I could do exactly
what your friend did.


Reason I completely forgot? I'm an idiot and was too busy replying to 3
emails at once whilst on a phone call.

My fault? Completely ;-)



Yes, see its called impulsive reasoning, hence the reason I added the
character class without needing it, embedding a character class
predicate such as \w inside a character class enclosure alone is well..
Stupid and reduntant at best..

Therefore there was some sub-concious reasoning to my madness I can
presume. And yes, I also know that that \w class wouldn't cover all the
characters I needed in a possible filename, again, I was careless and
quick


As for the compatibility of the \w character class within sed and awk:

I am well aware that this implementation works on Perl-Compatible
Regular Expression patterns, and is not a necessarily supported by all
regular expression standards

BUT WHO GIVES A FLYING FUCK?


But this is a PHP-DB list, he is asking a PHP related question and I
even specifically stated in my response:

preg_replace() which is a PCRE function using the PCRE pattern
modifiers.



And finally this is a mailing list, not a kindergarten room. We're here
to help, assist, and suggest advice. Not to wipe their bottoms.


I posted a suggestive solution to a problem. Thats all

SURE theres going to be different methods of approaching it, SURE it
could not be the most perfect pattern, but its a suggestion where to
head for the correct solution. HELL it wouldn't work with .asp files
either. Or if your files were named .php4 or .phtml

Do I give a damn about that?

No. Are you a tech support officer Jeremy? Do you need to help them
digest their baby jelly food?


Actually, enough of the hostility, I am honoured actually to think you
went to the effort of sending off my 10 second quick drafted suggestive
PCRE pattern off to Eric Pement of MBI..


Wow, touched. Imagine if I gave you guys some REAL PCRE patterns that I
use!!!

Now that you'd honour me for wouldn't you! I can just picture you two
drooling at the mouth now.



So is this Eric friend of yours some RegEx guru? I respect him if so, no
harm intended, but I do think my suggestive help posting to this list
was 'fit for purpose'

He never asked anyone to spoon feed him, and if you want to be a real
world developer you better learn to use your resources and reference
manuals.


I've had enough now.



Adios and cya later mate!


P.S. You (Jeremy) and Eric are Americans right?? :-) Just curious.
