Reading Directories

Frihost Forum Index -> Scripting -> Php and MySQL

Currently I have the following code to read the contents of a directory. I have two questions that I would appreciate being answered.

Current Code:

Code:

<html>
<head>
<title>Directory test</title>
</head>
<body>
<?php
$dirname = "pictures/art/";
$dh = opendir( $dirname ) or die("couldn't open directory");

while ( $file = readdir( $dh ) ) {
   if ( is_dir( "$dirname/$file" ) )
      print " ";
   print "$file<br>";
}
closedir( $dh );
?>
</body>
</html>

Firstly, the script outputs something like the following:

Quote:

.
..
a folder
another folder
file.ext
HouseTop.JPG
P1010783.JPG
P1010785.JPG
P1010786.JPG
P1010788.JPG
P1010789.JPG

My question, what does the . and the .. mean?

Secondly, I have some subfolders in that directory, how can I have the script read those too?

Thanks in advance.

I have found the following function which works. Does anyone have a simpler solution?

Quote:

Code:

function searchdir ( $path , $maxdepth = -1 , $mode = "FULL" , $d = 0 )
{
   if ( substr ( $path , strlen ( $path ) - 1 ) != '/' ) { $path .= '/' ; }
   $dirlist = array () ;
   if ( $mode != "FILES" ) { $dirlist[] = $path ; }
   if ( $handle = opendir ( $path ) )
   {
   while ( false !== ( $file = readdir ( $handle ) ) )
   {
      if ( $file != '.' && $file != '..' )
      {
      $file = $path . $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 ) ;
}

Here is a simpler version

Code:

<html>
<head>
<title>Directory test</title>
</head>
<body>
<?php
function recurseDir($dirname)
{
print "Directory: $dirname";
$dh = opendir( $dirname ) or die("couldn't open directory");

while ( $file = readdir( $dh ) )
{
if ( is_dir( "$dirname/$file" ) )
{
if( $file!="." && $file!="..")
recurseDir("$dirname/$file");
}
else
print "$file<br>";
}
closedir( $dh );
}

recurseDir("pictures/art");

?>
</body>
</html>

"." represents current directory and ".." represents parent of current directory.

Thanks, but I think I'll stay with the current one because it allows me to set the max depth and such.
