Get the hierarchy of a directory with PHP - php

Question

I'm trying to find all the files and folders under a specified directory
For example I have /home/user/stuff
I want to return
/home/user/stuff/folder1/image1.jpg
/home/user/stuff/folder1/image2.jpg
/home/user/stuff/folder2/subfolder1/image1.jpg
/home/user/stuff/image1.jpg
Hopefully that makes sense!

Answer 1

function dir_contents_recursive($dir) {
// open handler for the directory
$iter = new DirectoryIterator($dir);
foreach( $iter as $item ) {
// make sure you don't try to access the current dir or the parent
if ($item != '.' && $item != '..') {
if( $item->isDir() ) {
// call the function on the folder
dir_contents_recursive("$dir/$item");
} else {
// print files
echo $dir . "/" .$item->getFilename() . "<br>";
}
}
}
}

Answer 2

foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir)) as $f) {
echo "$f \r\n";
}

Answer 3

The working solution (change with your folder name)
<?php
$path = realpath('yourfolder/subfolder');
## or use like this
## $path = '/home/user/stuff/folder1';
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
{
echo "$filename\n";
}
?>

Answer 4

$dir = "/home/user/stuff/";
$scan = scandir($dir);
foreach ($scan as $output) {
echo "$output" . "<br />";
}

Answer 5

Find all the files and folders under a specified directory.
function getDirRecursive($dir, &$output = []) {
$scandir = scandir($dir);
foreach ($scandir as $a => $name) {
$path = realpath($dir . DIRECTORY_SEPARATOR . $name);
if (!is_dir($path)) {
$output[] = $path;
} else if ($name != "." && $name != "..") {
getDirRecursive($path, $output);
$output[] = $path;
}
}
return $output;
}
var_dump(getDirRecursive('/home/user/stuff'));
Output (example) :
array (size=4)
0 => string '/home/user/stuff/folder1/image1.jpg' (length=35)
1 => string '/home/user/stuff/folder1/image2.jpg' (length=35)
2 => string '/home/user/stuff/folder2/subfolder1/image1.jpg' (length=46)
3 => string '/home/user/stuff/image1.jpg' (length=27)

Answer 6

listAllFiles( '../cooktail/' ); //send directory path to get the all files and floder of root dir
function listAllFiles( $strDir ) {
$dir = new DirectoryIterator( $strDir );
foreach( $dir as $fileinfo ) {
if( $fileinfo == '.' || $fileinfo == '..' ) continue;
if( $fileinfo->isDir() ) {
listAllFiles( "$strDir/$fileinfo" );
}
echo $fileinfo->getFilename() . "<br/>";
}
}

Answer 7

Beside RecursiveDirectoryIterator solution there is also glob() solution:
// do some extra filtering here, if necessary
function recurse( $item ) {
return is_dir( $item ) ? array_map( 'recurse', glob( "$item/*" ) ) : $item;
};
// array_walk_recursive: any key that holds an array will not be passed to the function.
array_walk_recursive( ( recurse( 'home/user/stuff' ) ), function( $item ) { print_r( $item ); } );

Answer 8

You can use the RecursiveDirectoryIterator or even the glob function.
Alternatively, the scandir function will do the job.
