get current directory

Anon

hi,
i am trying to get the value of the current
directory. eg. I open the page called as
www.mydomain.com/phptest.php which on the
unix system is actually the following :
/usr/local/etc/httpd/htdocs/phptest.php

is there a function which will return me the
value of the direcory in which phptest.php
is present , in this case it should return
-- "/usr/local/etc/httpd/htdocs/"

I am stumped at this point! any help !!

cheers,
nilesh :-)

Without looking in the manual,
try:

$currentdir = system("pwd");
which (should!?!) execute the unix command PWD (print working directory)
...
There could be a function for returning the current dir too... look in the manual in file system... (www.zend.com/manual/ is one online manual)

Hope this helps

Well as long as you are only in your directories the front part of the path should always be the same. You can look at your current path by the $PATH_INFO variable
(I have heard that this can be different on various servers, use phpinfo to see what it is called on your server). Using $PATH_INFO will only give you the path after "/usr/local/etc/httpd/htdocs/"
then you can just join the two together to get the full path. So if you are in "/usr/local/etc/httpd/htdocs/folder/script.php3" $PATH_INFO will give you "/folder/script.php3"

hi,
found a solution for the problem.
the following code will throw the current
directory path into the $currentdir variable.

$currentdir = dirname($SCRIPT_FILENAME);
echo "<b>currentdir</b> $currentdir";

what this does is
1> $SCRIPT_FILENAME contains the whole path
of the unix eg /etc/httpd/htdocs/nilesh.php

2> the dirname() function returns the dir of
the passed $script_filename. in our case it
returns dirname(/etc/httpd/htdocs/nilesh.php)
which is /etc/httpd/htdocs (no end slashes)

Thanks jocke and brian for the tip.

I tryed with your example, but it doesn't work (?!?).

I found another quick solution:

$path = exec("pwd");

Enjoy!

here is the way to get the path to your root folder :
echo $DOCUMENT_ROOT;

Keep in mind, these environment variables must be declared global if used inside a function.

Use phpinfo() to see a list of all of the environment variables in your build of php.
