I`m trying to create a function that reads a directory and returns all file's working directories in an array, but it is not working. I don`t know why the code doesn`t work, can you help me?
$postsDirectory = "../posts/";
function listFiles() {
$results = array();
$handler = opendir($postsDirectory);
while ($file = readdir($handler)) {
if ($file != "." && $file != "..") {
$results[] = getcwd($file);
}
}
closedir($handler);
return $results;
}
getcwd() returns the working directory for the script that is being executed. It doesn't take any parameters, and it has nothing to do with other files on the file system (nor does the idea of a "working directory" make sense for an arbitrary file). I assume that what you actually want is a list of all directories within a given directory.
I would use a RecursiveDirectoryIterator for this:
$it = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($postsDirectory),
FilesystemIterator::SKIP_DOTS
);
$results = array();
while($it->valid()) {
if($it->isDir()) {
$results[] = $it->getSubPath();
}
$it->next();
}

A little stuck on this and hoping for some help. I'm trying to get the last modified dir from a path in a string. I know there is a function called "is_dir" and I've done some research but can't seem to get anything to work.
I don't have any code i'm sorry.
<?php
$path = '../../images/';
// echo out the last modified dir from inside the "images" folder
?>
For example: The path variable above has 5 sub folders inside the "images" dir currently right now. I want to echo out "sub5" - which is the last modified folder.
You can use scandir() instead of is_dir() function to do it.
Here is an example.
function GetFilesAndFolder($Directory) {
/*Which file want to be escaped, Just add to this array*/
$EscapedFiles = [
'.',
'..'
];
$FilesAndFolders = [];
/*Scan Files and Directory*/
$FilesAndDirectoryList = scandir($Directory);
foreach ($FilesAndDirectoryList as $SingleFile) {
if (in_array($SingleFile, $EscapedFiles)){
continue;
}
/*Store the Files with Modification Time to an Array*/
$FilesAndFolders[$SingleFile] = filemtime($Directory . '/' . $SingleFile);
}
/*Sort the result as your needs*/
arsort($FilesAndFolders);
$FilesAndFolders = array_keys($FilesAndFolders);
return ($FilesAndFolders) ? $FilesAndFolders : false;
}
$data = GetFilesAndFolder('../../images/');
var_dump($data);
From above example the last modified Files or Folders will show as Ascending order.
You can also separate your files and folder by checking is_dir() function and store the result in 2 different arrays like $FilesArray=[] and $FolderArray=[].
Details about filemtime() scandir() arsort()
Here's one way you can accomplish this:
<?php
// Get an array of all files in the current directory.
// Edit to use whatever location you need
$dir = scandir(__DIR__);
$newest_file = null;
$mdate = null;
// Loop over files in directory and if it is a subdirectory and
// its modified time is greater than $mdate, set that as the current
// file.
foreach ($dir as $file) {
// Skip current directory and parent directory
if ($file == '.' || $file == '..') {
continue;
}
if (is_dir(__DIR__.'/'.$file)) {
if (filemtime(__DIR__.'/'.$file) > $mdate) {
$newest_file = __DIR__.'/'.$file;
$mdate = filemtime(__DIR__.'/'.$file);
}
}
}
echo $newest_file;
This will work too just like the other answers. Thanks everyone for the help!
<?php
// get the last created/modified directory
$path = "images/";
$latest_ctime = 0;
$latest_dir = '';
$d = dir($path);
while (false !== ($entry = $d->read())) {
$filepath = "{$path}/{$entry}";
if(is_dir($filepath) && filectime($filepath) > $latest_ctime) {
$latest_ctime = filectime($filepath);
$latest_dir = $entry;
}
} //end loop
echo $latest_dir;
?>
I'm trying to list all PHP files in a specified directory and for it to recursively check all sub-directories until it finds no more, there could be numerous levels.
The function I have below works fine with the exception that it only recurses down one level.
I've spent hours trying to see where I'm going wrong, I'm calling the scanFiles() when it finds a new directory but this only seems to work one level down and stop, any help greatly appreciated.
Updated:
function scanFiles($pParentDirectory)
{
$vFileArray = scandir($pParentDirectory);
$vDirectories = array();
foreach ($vFileArray as $vKey => $vValue)
{
if (!in_array($vValue, array('.', '..')) && (strpos($vValue, '.php') || is_dir($vValue)))
{
if (!is_dir($vValue))
$vDirectories[] = $vValue;
else
{
$vDirectory = $vValue;
$vSubFiles = scanFiles($vDirectory);
foreach ($vSubFiles as $vKey => $vValue)
$vDirectories[] = $vDirectory.DIRECTORY_SEPARATOR.$vValue;
}
}
}
return $vDirectories;
}
You can do this easily like this:
// helper function
function getFiles(&$files, $dir) {
$items = glob($dir . "/*");
foreach ($items as $item) {
if (is_dir($item)) {
getFiles($files, $item);
} else {
if (end(explode('.', $item)) == 'php') {
$files[] = basename($item);
}
}
}
}
// usage
$files = array();
getFiles($files, "myDir");
// debug
var_dump($files);
myDir looks like this: has php files in all dirs
Output:
P.S. if you want the function to return the full path to the found .php files, remove the basename() from this line:
$files[] = basename($item);
This will then produce result like this:
hope this helps.
This is because $vDirectory is just a folder name, so scanDir looks in the current folder for it, not the sub folder.
What you want to do is to pass in the path to the folder, not just the name. This should be as simple as changing your recursive call to scanFiles($pParentDirectory . DIRECTORY_SEPARATOR . $vDirectory)
Your main problem is functions like scanDir or isDir need the full file path to work.
If you pass the full file path to them, it should work correctly.
I have a server with a lot of files inside various folders, sub-folders, and sub-sub-folders.
I'm trying to make a search.php page that would be used to search the whole server for a specific file. If the file is found, then return the location path to display a download link.
Here's what i have so far:
$root = $_SERVER['DOCUMENT_ROOT'];
$search = "test.zip";
$found_files = glob("$root/*/test.zip");
$downloadlink = str_replace("$root/", "", $found_files[0]);
if (!empty($downloadlink)) {
echo "$search";
}
The script is working perfectly if the file is inside the root of my domain name... Now i'm trying to find a way to make it also scan sub-folders and sub-sub-folders but i'm stuck here.
There are 2 ways.
Use glob to do recursive search:
<?php
// Does not support flag GLOB_BRACE
function rglob($pattern, $flags = 0) {
$files = glob($pattern, $flags);
foreach (glob(dirname($pattern).'/*', GLOB_ONLYDIR|GLOB_NOSORT) as $dir) {
$files = array_merge(
[],
...[$files, rglob($dir . "/" . basename($pattern), $flags)]
);
}
return $files;
}
// usage: to find the test.zip file recursively
$result = rglob($_SERVER['DOCUMENT_ROOT'] . '/test.zip');
var_dump($result);
// to find the all files that names ends with test.zip
$result = rglob($_SERVER['DOCUMENT_ROOT'] . '/*test.zip');
?>
Use RecursiveDirectoryIterator
<?php
// $regPattern should be using regular expression
function rsearch($folder, $regPattern) {
$dir = new RecursiveDirectoryIterator($folder);
$ite = new RecursiveIteratorIterator($dir);
$files = new RegexIterator($ite, $regPattern, RegexIterator::GET_MATCH);
$fileList = array();
foreach($files as $file) {
$fileList = array_merge($fileList, $file);
}
return $fileList;
}
// usage: to find the test.zip file recursively
$result = rsearch($_SERVER['DOCUMENT_ROOT'], '/.*\/test\.zip/'));
var_dump($result);
?>
RecursiveDirectoryIterator comes with PHP5 while glob is from PHP4. Both can do the job, it's up to you.
I want to provide another simple alternative for cases where you can predict a max depth. You can use a pattern with braces listing all possible subfolder depths.
This example allows 0-3 arbitrary subfolders:
glob("$root/{,*/,*/*/,*/*/*/}test_*.zip", GLOB_BRACE);
Of course the braced pattern could be procedurally generated.
This returns fullpath to the file
function rsearch($folder, $pattern) {
$iti = new RecursiveDirectoryIterator($folder);
foreach(new RecursiveIteratorIterator($iti) as $file){
if(strpos($file , $pattern) !== false){
return $file;
}
}
return false;
}
call the function:
$filepath = rsearch('/home/directory/thisdir/', "/findthisfile.jpg");
And this is returns like:
/home/directory/thisdir/subdir/findthisfile.jpg
You can improve this function to find several files like all jpeg file:
function rsearch($folder, $pattern_array) {
$return = array();
$iti = new RecursiveDirectoryIterator($folder);
foreach(new RecursiveIteratorIterator($iti) as $file){
if (in_array(strtolower(array_pop(explode('.', $file))), $pattern_array)){
$return[] = $file;
}
}
return $return;
}
This can call as:
$filepaths = rsearch('/home/directory/thisdir/', array('jpeg', 'jpg') );
Ref: https://stackoverflow.com/a/1860417/219112
As a full solution for your problem (this was also my problem):
<?php
function rsearch($folder, $pattern) {
$dir = new RecursiveDirectoryIterator($folder);
$ite = new RecursiveIteratorIterator($dir);
$files = new RegexIterator($ite, $pattern, RegexIterator::MATCH);
foreach($files as $file) {
yield $file->getPathName();
}
}
Will get you the full path of the items that you wish to find.
Edit: Thanks to Rousseau Alexandre for pointing out , $pattern must be regular expression.
I currently got the following code
glob(*.php)
foreach ($files as $files..)
$content = file_get_contents($file);
$cnt=count(explode("\n", $content))
$linecount += $cnt;
echo $linecount
I have a folder with .css, .html, .js and .php files in it. Now I would like to count all the lines of code I got int he files there. How can I do this?
I found this one here How to count all the lines of code in a directory recursively?
But it didn't really help me, because it seemed like you do what they did in a Linux shell. Any ideas?
This script counts all lines in all files in the specified directory:
$count = 0;
$handle = opendir('./'); //Path to your directory
while (false !== ($file = readdir($handle))) {
if($file != '.' && $file != '..' && !is_dir($file)) {
$content = file($file);
$count = $count + count($content);
}
}
echo 'Lines '.$count;
Well have seen folder names like include.php so your current method would not work. You also need to check sub folders so i would advice you to use RecursiveRegexIterator :
Example
$dir = new RecursiveDirectoryIterator(__DIR__, FilesystemIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator(
new RecursiveFileFilterIterator($dir, "/\.(css|html|js|php)$/"));
echo iterator_count($files);
Class Used
class RecursiveFileFilterIterator extends RecursiveRegexIterator {
public function accept() {
return parent::accept() && is_file($this->current());
}
}
I need to get all the folders and files from a folder recursively in alphabetical order (folders first, files after)
Is there an implemented PHP function which caters for this?
I have this function:
function dir_tree($dir) {
$path = '';
$stack[] = $dir;
while ($stack) {
$thisdir = array_pop($stack);
if ($dircont = scandir($thisdir)) {
$i=0;
while (isset($dircont[$i])) {
if ($dircont[$i] !== '.' && $dircont[$i] !== '..' && $dircont[$i] !== '.svn') {
$current_file = "{$thisdir}/{$dircont[$i]}";
if (is_file($current_file)) {
$path[] = "{$thisdir}/{$dircont[$i]}";
} elseif (is_dir($current_file)) {
$path[] = "{$thisdir}/{$dircont[$i]}";
$stack[] = $current_file;
}
}
$i++;
}
}
}
return $path;
}
I have sorted the array and printed it like so:
$filesArray = dir_tree("myDir");
natsort($filesArray);
foreach ($filesArray as $file) {
echo "$file<br/>";
}
What I need is to know when a new sub directory is found, so I can add some spaces to print it in a directory like structure instead of just a list.
Any help?
Many thanks
Look at the RecursiveDirectoryIterator.
$directory_iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir));
foreach($directory_iterator as $filename => $path_object)
{
echo $filename;
}
I'm not sure though if it returns the files in alphabetical order.
Edit:
As you say it does not, I think the only way is to sort them yourself.
I would loop through each directory and put directories and files in a seperate arrays, and then sort them, and then recurse in the directories.
I found a link which helped me a lot in what I was trying to achieve:
http://snippets.dzone.com/posts/show/1917
This might help someone else, it creates a list with folders first, files after. When you click on a subfolder, it submits and another page with the folders and files in the partent folder is generated.
