I use this code to list all files in directory:
$d = dir($FolderToPlay);
while (($file = $d->read()) !== false){
...
...
}
$d->close();
But, the result is not in the numerical order. How can I fix it?
Get a list of all the filenames, then you can use a sorting function.
$d = glob("$FolderToPlay/*");
natsort($d);
foreach ($d as $file) {
...
}
The easiest way to list all files in a directory is with scarndir() fuction.
You can use it like this:
//Create a variable that contains all your files
$root = scandir($dir);
//Do something with each value, like push them into an array, do regex etc.
foreach($root as $value){
//...
}

I need to search into folders and subfolders in search for files. In this search I need to know the files names and their path, because I have different folders and files inside of those.
I have this name 05-Navy, and inside this folder I have 3 files called 05_Navy_White_BaseColor.jpg, 05_Navy_White_Normal.jpg and 05_Navy_White_OcclusionRoughnessMetallic.jpg.
I need to only get one of them at a time because I need to add they separately to different lists.
Then I came up with the code below:
function getDirContents($dir, &$results = array()) {
$files = scandir($dir);
$findme = '_BaseColor';
$mypathCordas = null;
$findmeCordas = 'Cordas';
foreach ($files as $key => $value) {
$path = realpath($dir . DIRECTORY_SEPARATOR . $value);
$mypathCordas = $path;
$pos = strpos($mypathCordas, $findme);
$posCordas = strpos($mypathCordas, $findmeCordas);
if (!is_dir($path)) {
if($posCordas == true){
if($pos == true){
$results[] = $path;
}
}
}
else if ($value != "." && $value != ".." ) {
if($posCordas == true){
echo "</br>";
getDirContents($path, $results);
//$results[] = $path;
}
}
}
sort( $results );
for($i = 0; $i < count($results); $i++){
echo $results[$i];
echo "</br>";
}
return $results;
}
getDirContents('scenes/Texturas');
as output result I get this: Results1
Which is not ideal at all, the biggest problem is that the list inserts the same values every time it has do add new ones, and as you can see, it doesn't sort one bit, but it shuffles. I did other things, like I have tried to use DirectoryIterator which worked really well, but I couldn't sort at all...
The printing each time something new is on the list might be my for(), but I am relatively new to php, so I can't be sure.
Also, there's this thing where it gets all the path, and I already tried using other methods but got only errors, where I would only need the scenes/texturas/ instead of the absolute path....
I'm working on an IMDB style website and I need to dynamically find the amount of reviews for a movie. The reviews are stored in a folder called /moviefiles/moviename/review[*].txt where the [*] is the number that the review is. Basically I need to return as an integer how many of those files exist in that directory. How do I do this?
Thanks.
Use php DirectoryIterator or FileSystemIterator:
$directory = new DirectoryIterator(__DIR__);
$num = 0;
foreach ($directory as $fileinfo) {
if ($fileinfo->isFile()) {
if($fileinfo->getExtension() == 'txt')
$num++;
}
}
Take a look at the glob() function: http://php.net/manual/de/function.glob.php
You can then use sizeof() to count how many files there are.
First, use glob () to get file list array, then use count () to get array length, the array length is file count.
Simplify code:
$txtFileCount = count( glob('/moviefiles/moviename/review*.txt') );
You can use this php code to get the number of text files in a folder
<div id="header">
<?php
// integer starts at 0 before counting
$i = 0;
$dir = 'folder-path';
if ($handle = opendir($dir)) {
while (($file = readdir($handle)) !== false){
if (!in_array($file, array('.', '..')) && !is_dir($dir.$file))
{
$temp = explode(".",$file);
if($temp[1]=="txt")
$i++;
}
}
}
// prints out how many were in the directory
echo "There were $i files";
?>
</div>
This is a very simple code that works well. :)
$files = glob('yourfolder/*.{txt}', GLOB_BRACE);
foreach($files as $file) {
your work
}
I could use some help with this. I have to get list of files from one directory, and return them as array, but key needs to be the same as value, so output would be looking like this:
array(
'file1.png' => 'file1.png',
'file2.png' => 'file2.png',
'file3.png' => 'file3.png'
)
I found this code:
function images($directory) {
// create an array to hold directory list
$results = array();
// create a handler for the directory
$handler = opendir($directory);
// open directory and walk through the filenames
while ($file = readdir($handler)) {
// if file isn't this directory or its parent, add it to the results
if ($file != "." && $file != "..")
{
$results[] = $file;
}
}
// tidy up: close the handler
closedir($handler);
// done!
return $results;
}
It's working fine, but it returns regular array.
Can someone help me with this?
Also small note at the end, I need to list only image files (png,gif,jpeg).
Change your following line
$results[] = $file;
To
$results[$file] = $file;
To limit file extension do as below
$ext = pathinfo($file, PATHINFO_EXTENSION);
$allowed_files = array('png','gif');
if(in_array($ext,$allowed_files)){
$results[$file] = $file;
}
Something like this should to the work
$image_array = [];
foreach ($images as $image_key => $image_name) {
if ($image_key == $image_name) {
$image_array[] = $image_name;
}
return $image_array;
}
Why not using glob and array_combine ?
function images($directory) {
$files = glob("{$directory}/*.png");
return array_combine($files, $files);
}
glob() get files on your directory according to a standard pattern ( such as *.png )
array_combine() creates an associative array using an array of keys and an array of values
now do this on my script
$scan=scandir("your image directory");
$c=count($scan);
echo "<h3>found $c image.</h3>";
for($i=0; $i<=$c; $i++):
if(substr($scan[$i],-3)!=='png') continue;
echo "<img onClick=\"javascript:select('$scan[$i]');\" src='yourdirectory/$scan[$i]' />";
endfor;
this code only list png images from your directory.
I have this part of script that echos the folders in "albums" folder and arrange them by the alphabet, but for some reason it also includes an empty folder.
$directory = opendir("albums/");
$items = array();
while($items[] = readdir($directory))
sort($items);
closedir($directory);
foreach ($items as $item)
{
if(($item != ".") && ($item != "..")){
$files[] = $item;
}
}
What should I do? I think the if(($item != ".") && ($item != "..")) is part of my problem but I can't figure how to handle it.
The problem is with this line:
while($items[] = readdir($directory))
readdir returns false if no entries are left. That is why you have an extra item in $items
EDIT
while($item = readdir($directory))
{
$items[] = $item;
sort($items);
}
. is the current directory and .. is the parent directory. It's normal that readdir() returns these.
BTW you could simplify your code by using the glob() function:
$files = glob("albums/*");
// that's all
glob("albums/*") will return all entries in the albums directory, sorted alphabetically, and without the dot and dotdot entries.
Try this, as it's in sorted order, just array_shift() twice will do this work. But personally I think it's a kinda hacking...
<?php
$files = array();
foreach (glob('album/*') as $file) {
if (!is_dir($file)) {
$files[] = basename($file);
}
}
sort($files);
You can modify 'album/*' to suit your needs (ex. 'album/*.mp3'). Note that this method is not recursive, so if you need to process subdirectories within the album/ directory, you'll want to modify the code to account for this.
PHP manual for scandir: By default, the sorted order is alphabetical in ascending order.
I'm building a file browser (in Windows), so I want the addresses to be returned sorted by folder/file, then alphabetically in those subsets.
Example: Right now, I scan and output
Aardvark.txt
BarDir
BazDir
Dante.pdf
FooDir
and I want
BarDir
BazDir
FooDir
Aardvark.txt
Dante.pdf
Other than a usort and is_dir() solution (which I can figure out myself), is there a quick and efficient way to do this?
The ninja who wrote this comment is on the right track - is that the best way?
Does this give you what you want?
function readDir($path) {
// Make sure we have a trailing slash and asterix
$path = rtrim($path, '/') . '/*';
$dirs = glob($path, GLOB_ONLYDIR);
$files = glob($path);
return array_unique(array_merge($dirs, $files));
}
$path = '/path/to/dir/';
readDir($path);
Note that you can't glob('*.*') for files because it picks up folders named like.this.
Please try this. A simple function to sort the PHP scandir results by files and folders (directories):
function sort_dir_files($dir)
{
$sortedData = array();
foreach(scandir($dir) as $file)
{
if(is_file($dir.'/'.$file))
array_push($sortedData, $file);
else
array_unshift($sortedData, $file);
}
return $sortedData;
}
I'm late to the party but I like to offer my solution with readdir() rather than with glob(). What I was missing from the solution is a recursive version of your solution. But with readdir it's faster than with glob.
So with glob it would look like this:
function myglobdir($path, $level = 0) {
$dirs = glob($path.'/*', GLOB_ONLYDIR);
$files = glob($path.'/*');
$all2 = array_unique(array_merge($dirs, $files));
$filter = array($path.'/Thumbs.db');
$all = array_diff($all2,$filter);
foreach ($all as $target){
echo "$target<br />";
if(is_dir("$target")){
myglobdir($target, ($level+1));
}
}
}
And this one is with readdir but has basically the same output:
function myreaddir($target, $level = 0){
$ignore = array("cgi-bin", ".", "..", "Thumbs.db");
$dirs = array();
$files = array();
if(is_dir($target)){
if($dir = opendir($target)){
while (($file = readdir($dir)) !== false){
if(!in_array($file, $ignore)){
if(is_dir("$target/$file")){
array_push($dirs, "$target/$file");
}
else{
array_push($files, "$target/$file");
}
}
}
//Sort
sort($dirs);
sort($files);
$all = array_unique(array_merge($dirs, $files));
foreach ($all as $value){
echo "$value<br />";
if(is_dir($value)){
myreaddir($value, ($level+1));
}
}
}
closedir($dir);
}
}
I hope someone might find this useful.
