List all the files and folders in a Directory with PHP recursive function
php, recursion
Solution
Get all the files and folders in a directory, don't call function when you have `.` or `..`.
Your code :
<?php
function getDirContents($dir, &$results = array()) {
$files = scandir($dir);
foreach ($files as $key => $value) {
$path = realpath($dir . DIRECTORY_SEPARATOR . $value);
if (!is_dir($path)) {
$results[] = $path;
} else if ($value != "." && $value != "..") {
getDirContents($path, $results);
$results[] = $path;
}
}
return $results;
}
var_dump(getDirContents('/xampp/htdocs/WORK'));
Output (example) :
array (size=12)
0 => string '/xampp/htdocs/WORK/iframe.html' (length=30)
1 => string '/xampp/htdocs/WORK/index.html' (length=29)
2 => string '/xampp/htdocs/WORK/js' (length=21)
3 => string '/xampp/htdocs/WORK/js/btwn.js' (length=29)
4 => string '/xampp/htdocs/WORK/js/qunit' (length=27)
5 => string '/xampp/htdocs/WORK/js/qunit/qunit.css' (length=37)
6 => string '/xampp/htdocs/WORK/js/qunit/qunit.js' (length=36)
7 => string '/xampp/htdocs/WORK/js/unit-test.js' (length=34)
8 => string '/xampp/htdocs/WORK/xxxxx.js' (length=30)
9 => string '/xampp/htdocs/WORK/plane.png' (length=28)
10 => string '/xampp/htdocs/WORK/qunit.html' (length=29)
11 => string '/xampp/htdocs/WORK/styles.less' (length=30)
Problem
I'm trying to go through all of the files in a directory, and if there is a directory, go through all of its files and so on until there are no more directories to go to. Each and every processed item will be added to a results array in the function below. It is not working though I'm not sure what I can do/what I did wrong, but the browser runs insanely slow when this code below is processed, any help is appreciated, thanks! Code: ``` function getDirContents($dir){ $results = array(); $files = scandir($dir); foreach($files as $key => $value){ if(!is_dir($dir. DIRECTORY_SEPARATOR .$value)){ $results[] = $value; } else if(is_dir($dir. DIRECTORY_SEPARATOR .$value)) { $results[] = $value; getDirContents($dir. DIRECTORY_SEPARATOR .$value); } } } print_r(getDirContents('/xampp/htdocs/WORK')); ```
