I am having a problem using PHP 5.4 that has me wrapping my brain around it for hours now and it seems quite strange.
I am running a script to load classes based on a structure defined in an array.
The code is as follows:
$ds = DIRECTORY_SEPARATOR;
$directories = array(
'classes',
'classes/extendedClasses',
'controllers'
);
try{
foreach( $directories as $dir ){
$dirPath = realpath(__DIR__ . $ds . ".." . $ds . $dir);
if( !$dirPath ){
continue;
}
//var_dump($dirPath, '<br>');
$files = scandir($dirPath);
if( count($files) > 0 ){
foreach( $files as $file ){
if( empty($file) || $file == '.' || $file == '..' || strpos($file, '.php') === false ){
continue;
}
$toInclude = realpath($dirPath . $ds . $file);
if( file_exists($toInclude) ){
include_once($toInclude);
}
}
}
}
}Catch( Exception $ex ){
var_dump('Error in including dependencies');
exit(__METHOD__ . "--" . __LINE__);
}
When the code is executed i get a "The connection was reset error".
However, if i remove the line
'classes/extendedClasses',
From the code, i stop getting the error. Can anyone provide any insight as thus might be happening? Can it be related to the fact that i am trying to include something in a subdirectory? It doesn't make any sense to me.
Any help might be appreciated.
Thanks in advance,

I'd like my script to scandir recursively,
$files = scandir('/dir');
foreach($files as $file){
if(is_dir($file)){
echo '<li><label class="tree-toggler nav-header"><i class="fa fa-folder-o"></i>'.$file.'</label>';
$subfiles = scandir($rooturl.'/'.$file);
foreach($subfiles as $subfile){
// and so on and on and on
}
echo '<li>';
} else {
echo $file.'<br />';
}
}
I'd like to loop this in a way that for each dir found by scandir, it runs another scandir on the folders that have been found within that dir,
So dir 'A' contains dir 1/2/3, it should now scandir(1), scandir(2), scandir(3)
and so on for each dir found.
How can I manage to implement this easily without copy pasting the code over and over in every foreach?
EDIT: Since the answers are nearly the very same as I already tried, I'll update the question a bit.
With this script I need to create a treeview list. With the current posted scripts the following get's echo'd happens:
/images/dir1/file1.png
/images/dir1/file2.png
/images/dir1/file3.png
/images/anotherfile.php
/data/uploads/avatar.jpg
/data/config.php
index.php
What I actually need is:
<li><label>images</label>
<ul>
<li><label>dir1</label>
<ul>
<li>file1.png</li>
<li>file2.png</li>
<li>file3.png</li>
</ul>
</li>
<li>anotherfile.php</li>
</ul>
</li>
<li><label>data</label>
<ul>
<li><label>uploads</label>
<ul>
<li>avatar.jpg</li>
</ul>
</li>
<li>config.php</li>
</ul>
</li>
<li>index.php</li>
And so on, Thank you for the already posted answers!
I know this is an old question but I wrote a version of this that was more functional. It doesn't use global state and uses pure functions to figure things out:
function scanAllDir($dir) {
$result = [];
foreach(scandir($dir) as $filename) {
if ($filename[0] === '.') continue;
$filePath = $dir . '/' . $filename;
if (is_dir($filePath)) {
foreach (scanAllDir($filePath) as $childFilename) {
$result[] = $filename . '/' . $childFilename;
}
} else {
$result[] = $filename;
}
}
return $result;
}
You can scan directory recursively in this way the target is your top most directory:
function scanDir($target) {
if(is_dir($target)){
$files = glob( $target . '*', GLOB_MARK ); //GLOB_MARK adds a slash to directories returned
foreach( $files as $file )
{
scanDir( $file );
}
}
}
You can adapt this function for your need easily.
For example if would use this to delete the directory and its content you could do:
function delete_files($target) {
if(is_dir($target)){
$files = glob( $target . '*', GLOB_MARK ); //GLOB_MARK adds a slash to directories returned
foreach( $files as $file )
{
delete_files( $file );
}
rmdir( $target );
} elseif(is_file($target)) {
unlink( $target );
}
You can not do this in the way you are doing.
The following function gets recursively all the directories, sub directories so deep as you want and the content of them:
function assetsMap($source_dir, $directory_depth = 0, $hidden = FALSE)
{
if ($fp = #opendir($source_dir))
{
$filedata = array();
$new_depth = $directory_depth - 1;
$source_dir = rtrim($source_dir, '/').'/';
while (FALSE !== ($file = readdir($fp)))
{
// Remove '.', '..', and hidden files [optional]
if ( ! trim($file, '.') OR ($hidden == FALSE && $file[0] == '.'))
{
continue;
}
if (($directory_depth < 1 OR $new_depth > 0) && #is_dir($source_dir.$file))
{
$filedata[$file] = assetsMap($source_dir.$file.'/', $new_depth, $hidden);
}
else
{
$filedata[] = $file;
}
}
closedir($fp);
return $filedata;
}
echo 'can not open dir';
return FALSE;
}
Pass your path to the function:
$path = 'elements/images/';
$filedata = assetsMap($path, $directory_depth = 5, $hidden = FALSE);
$filedata is than an array with all founded directories and sub directories with their content. This function lets you scan the directories structure ($directory_depth) so deep as you want as well get rid of all the boring hidden files (e.g. '.','..')
All you have to do now is to use the returned array, which is the complete tree structure, to arrange the data in your view as you like.
What you are trying to do is in fact a kind of file manager and as you know there are a lot of those in the wild, open source and free.
I hope this will help you and I wish you a merry Christmas.
function getFiles(string $directory, array $allFiles = []): array
{
$files = array_diff(scandir($directory), ['.', '..']);
foreach ($files as $file) {
$fullPath = $directory. DIRECTORY_SEPARATOR .$file;
if( is_dir($fullPath) )
$allFiles += getFiles($fullPath, $allFiles);
else
$allFiles[] = $file;
}
return $allFiles;
}
I know this is old but i wanted to show a slightly different version of the other answers. Uses array_diff to discard the "." and ".." folders. Also the + operator to combine 2 arrays ( i rarely see this used so it might be useful for someone )
Though the question is old. But my answer could help people who visit this question.
This recursively scans the directory and child directories and stores the output in a global variable.
global $file_info; // All the file paths will be pushed here
$file_info = array();
/**
*
* #function recursive_scan
* #description Recursively scans a folder and its child folders
* #param $path :: Path of the folder/file
*
* */
function recursive_scan($path){
global $file_info;
$path = rtrim($path, '/');
if(!is_dir($path)) $file_info[] = $path;
else {
$files = scandir($path);
foreach($files as $file) if($file != '.' && $file != '..') recursive_scan($path . '/' . $file);
}
}
recursive_scan('/var/www/html/wp-4.7.2/wp-content/plugins/site-backup');
print_r($file_info);
Create a scan function and call it recursively...
e.g:
<?php
function scandir_rec($root)
{
echo $root . PHP_EOL;
// When it's a file or not a valid dir name
// Print it out and stop recusion
if (is_file($root) || !is_dir($root)) {
return;
}
// starts the scan
$dirs = scandir($root);
foreach ($dirs as $dir) {
if ($dir == '.' || $dir == '..') {
continue; // skip . and ..
}
$path = $root . '/' . $dir;
scandir_rec($path); // <--- CALL THE FUNCTION ITSELF TO DO THE SAME THING WITH SUB DIRS OR FILES.
}
}
// run it when needed
scandir_rec('./rootDir');
You can do a lot variation of this function. Printing a 'li' tag instead of PHP_EOL for instance, to create a tree view.
[EDIT]
<?php
function scandir_rec($root)
{
// if root is a file
if (is_file($root)) {
echo '<li>' . basename($root) . '</li>';
return;
}
if (!is_dir($root)) {
return;
}
$dirs = scandir($root);
foreach ($dirs as $dir) {
if ($dir == '.' || $dir == '..') {
continue;
}
$path = $root . '/' . $dir;
if (is_file($path)) {
// if file, create list item tag, and done.
echo '<li>' . $dir . '</li>';
} else if (is_dir($path)) {
// if dir, create list item with sub ul tag
echo '<li>';
echo '<label>' . $dir . '</label>';
echo '<ul>';
scandir_rec($path); // <--- then recursion
echo '</ul>';
echo '</li>';
}
}
}
// init call
$rootDir = 'rootDir';
echo '<ul>';
scandir_rec($rootDir);
echo '</ul>';
Modern way:
use RecursiveIteratorIterator;
use RecursiveDirectoryIterator;
$path = '/var/www/path/to/your/files/';
foreach ( new RecursiveIteratorIterator( new RecursiveDirectoryIterator( $path, RecursiveDirectoryIterator::SKIP_DOTS ) ) as $file ) {
// TODO: Uncomment to see additional information. Do your manipulations with the files here.
// var_dump( $file->getPathname() ); // Or simple way: echo $file;
// var_dump( $file->isFile() );
// var_dump( $file->isDir() );
// var_dump( $file->getFileInfo() );
// var_dump( $file->getExtension() );
// var_dump( $file->getDepth() );
}
function deepScan($dir = __DIR__){
static $allFiles = [];
$allFiles[$dir] = [];
$directories = array_values(array_diff(scandir($dir), ['.', '..']));
foreach($directories as $directory){
if(is_dir("$dir\\$directory")){
foreach(deepScan("$dir\\$directory") as $key => $value) $allFiles[$key] = $value;
}
else{
$allFiles[$dir][] = "$directory";
}
}
return $allFiles;

Im really new to PHP i searched google to find a correct script that loops through all subfolders in a folder and get all files path in that subfolder
<?php
$di = new RecursiveDirectoryIterator('posts');
foreach (new RecursiveIteratorIterator($di) as $filename => $file) {
echo $filename. '<br/>';
}
?>
So i have folder 'posts' in which i have subfolder 'post001' in which i have two files
controls.png
text.txt
And the code above echos this
posts\.
posts\..
posts\post001\.
posts\post001\..
posts\post001\controls.png
posts\post001\text.txt
But i want to echo only the file paths inside these subfolders like this
posts\post001\controls.png
posts\post001\text.txt
The whole point of this is that i want to dynamically create divs for each subfolder and inside this div i put img with src and some h3 and p html tags with text equal to the .txt file so is this proper way of doing that and how to remake my php script so that i get just the file paths
So I can see the answers and they are all correct but now my point was that i need something like that
foreach( glob( 'posts/*/*' ) as $filePath ){
//create div with javascript
foreach( glob( 'posts/$filePath/*' ) as $file ){
//append img and h3 and p html tags to the div via javascript
}
//append the created div somewhere in the html again via javascript
}
So whats the correct syntax of doing these two foreach loops in php im really getting the basics now
See if this works :)
$di = new RecursiveDirectoryIterator('posts');
foreach (new RecursiveIteratorIterator($di) as $filename => $file) {
if ((substr($file, -1) != '.') && (substr($file, -2) != '..')) {
echo $file . '<br/>';
}
}
<h1>Directory Listing</h1>
<?php
/**
* Recursive function to append the full path of all files in a
* given directory $dirpath to an array $context
*/
function getFilelist($dirpath, &$context){
$fileArray = scandir($dirpath);
if (count($fileArray) > 2) {
/* Remove the . (current directory) and .. (parent directory) */
array_shift($fileArray);
array_shift($fileArray);
foreach ($fileArray as $f) {
$full_path = $dirpath . DIRECTORY_SEPARATOR . $f;
/* If the file is a directory, call the function recursively */
if (is_dir($full_path)) {
getFilelist($full_path, $context);
} else {
/* else, append the full path of the file to the context array */
$context[] = $full_path;
}
}
}
}
/* $d is the root directory that you want to list */
$d = '/Users/Shared';
/* Allocate the array to store of file paths of all children */
$result = array();
getFilelist($d, $result);
$display_length = false;
if ($display_length) {
echo 'length = ' . count($result) . '<br>';
}
function FormatArrayAsUnorderedList($context) {
$ul = '<ul>';
foreach ($context as $c) {
$ul .= '<li>' . $c . '</li>';
}
$ul .= '</ul>';
return $ul;
}
$html_list = FormatArrayAsUnorderedList($result);
echo $html_list;
?>
Take a look at this:
<?php
$filename[] = 'posts\.';
$filename[] = 'posts\..';
$filename[] = 'posts\post001\.';
$filename[] = 'posts\post001\..';
$filename[] = 'posts\post001\controls.png';
$filename[] = 'posts\post001\text.txt';
foreach ($filename as $file) {
if (substr($file, -4, 1) === ".") {
echo $file."<br>";
}
}
?>
Result:
posts\post001\controls.png
posts\post001\text.txt
What this does is checking if the 4th last digit is a dot. If so, its an extension of three letters and it should be a file. You could also check for specific extensions.
$ext = substr($file, -4, 4);
if ($ext === ".gif" || $ext === ".jpg" || $ext === ".png" || $ext === ".txt") {
echo $file."<br>";
}

I have a wordpress theme that uses glob() function. THe problem is my hosting company has disabled glob(). how to modify the code so that it works using other php functions (opendir() maybe ?)
here is the code:
function yiw_get_tabs_path_files() {
$theme_files_path = YIW_THEME_FUNC_DIR . 'theme-options/';
$core_files_path = YIW_FRAMEWORK_PATH . 'theme-options/options/';
$tabs = array();
foreach ( glob( $theme_files_path . '*.php' ) as $filename ) {
preg_match( '/(.*)-options\.(.*)/', basename( $filename ), $filename_parts );
$tab = $filename_parts[1];
$tabs[$tab] = $filename;
}
foreach ( glob( $core_files_path . '*.php' ) as $filename ) {
preg_match( '/(.*)-options\.(.*)/', basename( $filename ), $filename_parts );
$tab = $filename_parts[1];
$tabs[$tab] = $filename;
}
return $tabs;
}
You can use the combination of opendir, readdir and closedir as you
suggested.
// open the directory
if ($handle = opendir($file_path)) {
// iterate over the directory entries
while (false !== ($entry = readdir($handle))) {
// match on .php extension
if (preg_match('/\.php$/', $entry) {
...
}
}
// close the directory
closedir($handle);
}
If these too are disabled, you can try the object-oriented Directory class.
I want to change some code by replacing it with blank space in all php and other files in my project folder and sub folder files.
I have the following code.
if ($handle = # opendir("for testing")) {
while (($entry = readdir($handle)) ) {
if ($entry != "." && $entry != "..") {
$linecop = '/*god_mode_on*eval(test("ZXkViKSk7IA=="));*god_mode_off*/';
$homepage = file_get_contents($entry);
$string3=str_replace($linecop,'',$homepage);
$file = fopen($entry, "w") or exit("Unable to open file!");
fwrite($file, $string3);
fclose($file); //
}
}
closedir($handle);
}
But this code only works for one file. How do I change all files?
function recursive_replace( $directory, $search, $replace ) {
if ( ! is_dir( $directory ) ) return;
foreach ( glob( $directory . '/*' ) as $file ) {
if ( $file === '.' || $file === '..' ) continue;
if ( is_dir( $file ) ) recursive_replace( $file, $search, $replace );
$content = file_get_contents( $file );
$content = str_replace( $search, $replace, $content );
file_put_contents( $file, $content );
}
}
recursive_replace('/your/file/path', '/*god_mode_on*eval(test("ZXkViKSk7IA=="));*god_mode_off*/', '');
if you want to recursively search and replace, you should think of a recursive function :) Also, glob()/file_X_contents() are much nicer functions to use for file and directory needs. code not tested but is damn close to what you're looking for in any case.
