Windows directory listings

Hi,

I am trying to write a script that reads a directory on Windows. All the PHP
functions I have looked at all seem to work with the Linux dietary
structure. Is there another way to do this.

Thanks

Something like this:

$dh = @opendir ($Somepath);
while ($file = @readdir ($dh)) {
if (($file!="..") && ($file!=".")) {
echo $file;
}
}

it sounds more like you have found an examples that show windows
being used (i.e. windows file paths).

you must be reading a manual that only exists in your particular parallel
universe, all relevant php function work in windows as well as linux:

http://php.net/manual/en/ref.filesystem.php
http://php.net/dir

Maybe I should clarify. When I use a windows path (c:\whatever) I get an
error that it can't find the path. In Linux the same code works fine
(/usr/local/whatever).

Here is all the relevent info.

Warning: opendir(f:\downloads\): failed to open dir: Invalid argument in
c:\web\index.php on line 30

***** This is line 30 - if ( $handle = opendir ( $page ) )

This is the code:

$page = "f:\\downloads";
// $mode : "FULL"|"DIRS"|"FILES"
// $d : must not be defined

$display = searchdir($page);

$num = count($display);
$i = 0;

for($i = 0; $i <= $num; $i++) { echo $i." ".$display[$i]."<br>"; }



function searchdir ( $page , $maxdepth = -1 , $mode = "FILES" , $d = 0 ) {
if ( substr ( $page , strlen ( $page ) - 1 ) != '\\' ) { $page .= '\\' ;
}
$dirlist = array () ;
if ( $mode != "FILES" ) { $dirlist[] = $page ; }
if ( $handle = opendir ( $page ) )
{
while ( false !== ( $file = readdir ( $handle ) ) )
{
if ( $file != '.' && $file != '..' )
{
$file = $file ;
if ( ! is_dir ( $file ) ) { if ( $mode != "DIRS" ) {
$dirlist[] = $file ; } }
elseif ( $d >=0 && ($d < $maxdepth || $maxdepth < 0) )
{
$result = searchdir ( $file . '\\' , $maxdepth , $mode ,
$d + 1 ) ;
$dirlist = array_merge ( $dirlist , $result ) ;
}
}
}
closedir ( $handle ) ;
}
if ( $d == 0 ) { natcasesort ( $dirlist ) ; }
return ( $dirlist ) ;
}

?>

with regard to trolling - I'd don't *just* do that :-)

sometime I even get the answer to the question correct :-)
let's see if I can help ...

you got this part right (escaping the backslash)

this if statement will run given the value of $page, it's not needed AFAIKT.
then again I can't see it causing problems.

btw: php defines a constant DIRECTORY_SEPARATOR automatically which may help you
make your code more portable, and save you having to think/worry about the blacksdlashing
'problem'.

right here I suggest adding a check using is_dir() and is_readable() on the $page var.
for now stick in a bit of debug code ...

echo '<pre>';
var_dump($path, is_dir($path), is_readable($path));
echo '</pre>';

I'm guessing that is_readable() is going to return false, which would point
the fact that either the drive or the directory is not readable by the webserver
process (you don't mention whether you are running via a the webserver but I assume you
are given the output your generating include a '<br>') - the situation maybe compounded
by the fact that F: is actually a mapped drive of some sorts (I have no idea
what kind of trouble this could cause).

This makes no difference. I took it out before and got the same error.

I checked the NTFS permissions and they are fine, and the local directory
displays fine. By this I mean the directory where this script is.

So if the script is in c:\test I can read c:\test, c:\test\test2.
c:\test\test3, ../test2. etc. It only happens when I go outside of the
current drive.

So if I put $page = "test", or $page = "test3", or $page = "../" they will
all work. As soon as I add a drive letter, it gives me the error. Even on
the local machine.

I am trying to access a networked drive, but I have a share on the PC where
the script is . May this is the issue. Is there a way to use a UNC path?

I didn't think it would.

the mapped drive should not be a problem. I definitely think it's a permission issue,
of course I could be wrong.

the following bug report *might* give you a clue as to whats going on:

http://bugs.php.net/bug.php?id=22153&edit=1

I have a feeling the bit about setting the permissions of the Share
to Everyone (on the server) is a good place to start. (the point about
having to login to the share manually before php is able to connect is also
noteworthy)

also bare in mind that a Drive/Directory has a set of permissions that are
seperate to the permissions of a Share that is defined for said Drive/Directory,
(something that has always confused me a bit) - both need to be setup to appropriately

> Is there a way to use a UNC path?

things I came across suggests this can work - something like?:

$dir = opendir(""\\\\your.ip.add.ress\\your_share"");

What are the permissions set on the mapped drive? That's what will
determine access.
