XXIV. Funzioni per le directoryRequisitiQueste funzioni sono disponibili nei moduli standard,
che sono sempre disponibili. IstallazioneNon ` necessaria nessuna installazione per usare queste
funzioni, esse fanno parte del core di PHP. Configurazione RuntimeQuesta estensione non definisce
alcuna direttiva di configurazione Costanti PredefiniteQuesta estensione non definisce alcuna costante. - Sommario
- chdir -- cambia directory
- chroot -- cambia la direcory di root
- dir -- classe directory
- closedir -- chiude l'handle della directory
- getcwd -- restituisce la directory di lavoro in uso

List all files in a directory tree under Win32:
function
list_dir($dirname)
{
if($dirname[strlen($dirname)-1]!='\\')
$dirname.='\\';
static
$result_array=array();
$handle=opendir($dirname);
while ($file
=
readdir($handle))
{
if($file=='.'||$file=='..')
continue;
if(is_dir($dirname.$file))
list_dir($dirname.$file.'\\');
else
$result_array[]=$dirname.$file;
}
closedir($handle);
return
$result_array;
}

The user annotation above it not correct: one should really use 'identical'
to check for FALSE, as a directory may be named FALSE as
well...
Thus:
while ($file =
readdir($handle))
should read
while (false !== ($file =
readdir($handle)))

Arjan.

Just a side note....not really php'ish
$mstrng = shell_exec('du -sc
/usr/local/apache/www');
print "$mstrng";
Will get you
the size of a directory, including all of its sub dirs and files within.

array filelist (string directory)
This function will recurse all
dirs below the specified directory and return with a list of all the
files, e.g.
$listoffiles = filelist ("/download");
where
/download has the following
structure:
/download/file.html
/download/somefolder/anotherfile.tar
/download/somefolder/someotherfolder/afileagain.php
will
return
$listoffiles = array (
[0] =>
"file.html",
[1] => "anotherfile.tar",
[2]
=> "afileagain.php"
)
I hope you will find this
useful.

// File listing function
function

($currentdir);
// remember where we started from
if
(!$startdir) {
$startdir = $currentdir;
}
$d = opendir
(".");
//list the files in the dir
while ($file =
readdir ($d)) {
if ($file != ".." && $file !=
".") {
if (is_dir ($file)) {
// If $file is a
directory take a look inside
$files = filelist (getcwd().'/'.$file,
getcwd(), $files);
} else {
// If $ file is not a directory
then add it to our output array
$files[] =
$file;
}

In [email protected]'s function
list_dir($dirname):
if(is_dir($dirname.$file))
list_dir($dirname.$file.'\\');
should
become:
if(is_dir($dirname.$file))
$result_array[]=list_dir($dirname.$file.'\\');
or recursion
will be done, but no subdirs will be pushed into the
$result_array.

This script will count lines of code that do not begin with // or are not
blank space. It's very approximate because it will include /* */ comments
and will also include lines that start with blank space and then //. It's
a start though (it's recursive, so don't use this with a directory
structure that includes symbolic links). This will recursively count all
the lines of files that end with .php. You can change .php to whatever,
and also change the guidelines as to whether a line qualifies as a comment
or not (look around the !="//"
part)
$i=0;
function getDirList ($dirName) {
global $i;
$d = dir($dirName);
while($entry
= $d->read()) {
if ($entry != "."
&& $entry != "..") {
if (is_dir($dirName."/".$entry)) {
getDirList($dirName."/".$entry);
} else if(substr($entry, -4)=='.php') {
if($read_file = file($dirName.'/'.$entry))
foreach($read_file as
$line)
if(($line!="\n") && (substr($line, 0,
2)!="//"))
$i++;
echo
$dirName."/".$entry."\n";
}
}
}
$d->close();
}
getDirList("./path/to/files");
echo $i;

Note that all directory functions will not work if PHP is running in
"safe mode" and the uid of the script is not the uid of the dir
owner.

Small script to list all files + size + date (like the DOS dir
command)
//define the path as relative
$path =
".";
//using the opendir function
$dir_handle =
@opendir($path) or die("Unable to open $path");
//make string with 70 spaces
$space="
";
echo
"<PRE>";
echo "Directory Listing of
$path\n";
//running the while loop
while ($file =
readdir($dir_handle)) {
// filename - output
left-justified
$t="<a
href=$file>$file</a>";
echo
$t.substr($space,0,40-strlen($file)) ;
//
filesize - output right-justified
$t=(filesize($file)/1024);
$t=sprintf("%01.2f",$t)."kb ";
echo
substr($space,0,10-strlen($t)) . $t ;
// filedate
- output left-justified
$t=date("d.M Y H:i:s",
filemtime($file));
echo $t.substr($space,0,20-strlen($file))
;
echo "\n";
}
//closing the
directory
closedir($dir_handle);
echo
"</PRE>";
