Listing all the folders subfolders and files in a directory using php
Please give me a solution for listing all the folders,subfolders,files in a directory using php. My folder structure is like this:
Main Dir
Dir1
SubDir1
File1
File2
SubDir2
File3
File4
Dir2
SubDir3
File5
File6
SubDir4
File7
File8
I want to get the list of all the files inside each folder.
Is there any shell script command in php?
Solution 1:
function listFolderFiles($dir){
$ffs = scandir($dir);
unset($ffs[array_search('.', $ffs, true)]);
unset($ffs[array_search('..', $ffs, true)]);
// prevent empty ordered elements
if (count($ffs) < 1)
return;
echo '<ol>';
foreach($ffs as $ff){
echo '<li>'.$ff;
if(is_dir($dir.'/'.$ff)) listFolderFiles($dir.'/'.$ff);
echo '</li>';
}
echo '</ol>';
}
listFolderFiles('Main Dir');
Solution 2:
A very simple way to show folder structure makes use of RecursiveTreeIterator class (PHP 5 >= 5.3.0, PHP 7) and generates an ASCII graphic tree.
$it = new RecursiveTreeIterator(new RecursiveDirectoryIterator("/path/to/dir", RecursiveDirectoryIterator::SKIP_DOTS));
foreach($it as $path) {
echo $path."<br>";
}
http://php.net/manual/en/class.recursivetreeiterator.php
There is also some control over the ASCII representation of the tree by changing the prefixes using RecursiveTreeIterator::setPrefixPart, for example $it->setPrefixPart(RecursiveTreeIterator::PREFIX_LEFT, "|");
Solution 3:
This code lists all directories and files in sorted order in a tree view. It's a site map generator with hyper-links to all the site resources. The full web page source is here. You'll need to change the path on the ninth line from the end.
<?php
$pathLen = 0;
function prePad($level)
{
$ss = "";
for ($ii = 0; $ii < $level; $ii++)
{
$ss = $ss . "| ";
}
return $ss;
}
function myScanDir($dir, $level, $rootLen)
{
global $pathLen;
if ($handle = opendir($dir)) {
$allFiles = array();
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
if (is_dir($dir . "/" . $entry))
{
$allFiles[] = "D: " . $dir . "/" . $entry;
}
else
{
$allFiles[] = "F: " . $dir . "/" . $entry;
}
}
}
closedir($handle);
natsort($allFiles);
foreach($allFiles as $value)
{
$displayName = substr($value, $rootLen + 4);
$fileName = substr($value, 3);
$linkName = str_replace(" ", "%20", substr($value, $pathLen + 3));
if (is_dir($fileName)) {
echo prePad($level) . $linkName . "<br>\n";
myScanDir($fileName, $level + 1, strlen($fileName));
} else {
echo prePad($level) . "<a href=\"" . $linkName . "\" style=\"text-decoration:none;\">" . $displayName . "</a><br>\n";
}
}
}
}

Solution 4:
In case you want to use directoryIterator
Following function is a re-implementation of @Shef answer with directoryIterator
function listFolderFiles($dir)
{
echo '<ol>';
foreach (new DirectoryIterator($dir) as $fileInfo) {
if (!$fileInfo->isDot()) {
echo '<li>' . $fileInfo->getFilename();
if ($fileInfo->isDir()) {
listFolderFiles($fileInfo->getPathname());
}
echo '</li>';
}
}
echo '</ol>';
}
listFolderFiles('Main Dir');
Solution 5:
I'm really fond of SPL Library, they offer iterator's, including RecursiveDirectoryIterator.
