I am using the following php to scan a directory and output the files.
I need to order these alphabetically but not sure how to do this.
This is what I have so far:
<?php
// path to directory
$directory = "gallery/photos/";
// open the directory
$handle = openDir($directory);
// Read the directory
while ($file = readDir($handle)) {
// filter the directory
if ($file != "." && $file != ".." && !is_dir($file)) {
// Allow only images (filter)
if (strstr($file, ".gif") || strstr($file, ".png") || strstr($file, ".PNG") || strstr($file, ".jpg")) {
// Path to the actual file
$directory_file = $directory . $file;
// Get image information (width, height)
$info = getImageSize($directory_file);
// show the picture
echo "<img src=\"$directory_file\" data-title=\"$file\"";
echo " width=\"$info[0]\" height=\"$info[1]\"> <br>\n";
}
}
}
// Close the directory
closeDir($handle);
?>
Use scandir instead which returns the files in alphabetical order
$arr = array_diff( scandir ( $directory ), ['.', '..'] );
// We are remmoving . and .. at this place
foreach($file in $arr){
// do your stuff
}

I want to delete files in a specific directory in PHP. How can I achieve this?
I have the following code but it does not delete the files.
$files = array();
$dir = dir('files');
while ($file = $dir->read()) {
if ($file != '.' && $file != '..') {
$files[] = $file;
}
unlink($file);
}
I think your question isn't specific, this code must clear all files in the directory 'files'.
But there are some errors in that code I think, and here is the right code:
$files= array();
$dir = dir('files');
while (($file = $dir->read()) !== false) { // You must supply a condition to avoid infinite looping
if ($file != '.' && $file != '..') {
$files[] = $file; // In this array you push the valid files in the provided directory, which are not (. , ..)
}
unlink('files/'.$file); // This must remove the file in the queue
}
And finally make sure that you provided the right path to dir().
You can get all directory contents with glob and check if the value is a file with is_file() before unlinking it.
$files = glob('files/*'); // get directory contents
foreach ($files as $file) { // iterate files
// Check if file
if (is_file($file)) {
unlink($file); // delete file
}
}
If you want to remove files matching a pattern like .png or .jpg, you have to use
$files = glob('/tmp/*.{png,jpg}', GLOB_BRACE);
See manual for glob.
I use the code suggested here

This is what I have now.
<?php
$dir = "sliders/slides";
$images = array();
if (is_dir($dir))
{
if ($dh = opendir($dir))
{
while (($file = readdir($dh)) !== false)
{
if (!is_dir($dir.$file)) $images[] = $dir . '/' . $file;
}
closedir($dh);
}
}
echo json_encode($images);
?>
My result includes 2 extra items
sliders/slides/.
sliders/slides/..
which makes my slider having 2 extra blank slides
How can I filter the result to show only .jpg and .png files in order to remove /. and /.. be included in the results
I'm trying to create sliders that gets images from a folder
Thanks
Try something like this inside the while :
if ($file != "." && $file != ".." && !is_dir($file) {
$images[] = $dir . '/' . $file;
}
I am allowing users to upload portfolios in ZIP archives on my site.
The problem is that most archives have the following folder structure:
zipfile.zip
- zipfile
- file1.ext
- file2.ext
- file3.ext
is there any way to simply put the files (not the directory) onto my site (so the folder structure of their portfolio is like so)
user_name
- portfolio
- file1.ext
- file2.ext
- file3.ext
it currently uploads them like so:
user_name
- portfolio
- zipfile
- file1.ext
- file2.ext
- file3.ext
which creates all kinds of problems!
I have tried doing this:
$zip = new ZipArchive();
$zip->open($_FILES['zip']['tmp_name']);
$folder = explode('.', $_FILES['zip']['name']);
end($folder);
unset($folder[key($folder)]);
$folder = (implode('.', $folder));
$zip->extractTo($root, array($folder));
$zip->close();
to no avail.
You could do something like this:
Extract Zip file to a temp location.
Scan through it and move(copy) all the files to portfolio folder.
Delete the temp folder and its all contents (created in Step 1).
Code:
//Step 01
$zip = new ZipArchive();
$zip->open($_FILES['zip']['tmp_name']);
$zip->extractTo('temp/user');
$zip->close();
//Define directories
$userdir = "user/portfolio"; // Destination
$dir = "temp/user"; //Source
//Step 02
// Get array of all files in the temp folder, recursivly
$files = dirtoarray($dir);
// Cycle through all source files to copy them in Destination
foreach ($files as $file) {
copy($dir.$file, $userdir.$file);
}
//Step 03
//Empty the dir
recursive_directory_delete($dir);
// Functions Code follows..
//to get all the recursive paths in a array
function dirtoarray($dir, $recursive) {
$array_items = array();
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
if (is_dir($dir. "/" . $file)) {
if($recursive) {
$array_items = array_merge($array_items, dirtoarray($dir. "/" . $file, $recursive));
}
} else {
$file = $dir . "/" . $file;
$array_items[] = preg_replace("/\/\//si", "/", $file);
}
}
}
closedir($handle);
}
return $array_items;
}
// Empty the dir
function recursive_directory_delete($dir)
{
// if the path has a slash at the end we remove it here
if(substr($directory,-1) == '/')
{
$directory = substr($directory,0,-1);
}
// if the path is not valid or is not a directory ...
if(!file_exists($directory) || !is_dir($directory))
{
// ... we return false and exit the function
return FALSE;
// ... if the path is not readable
}elseif(!is_readable($directory))
{
// ... we return false and exit the function
return FALSE;
// ... else if the path is readable
}else{
// we open the directory
$handle = opendir($directory);
// and scan through the items inside
while (FALSE !== ($item = readdir($handle)))
{
// if the filepointer is not the current directory
// or the parent directory
if($item != '.' && $item != '..')
{
// we build the new path to delete
$path = $directory.'/'.$item;
// if the new path is a directory
if(is_dir($path))
{
// we call this function with the new path
recursive_directory_delete($path);
// if the new path is a file
}else{
// we remove the file
unlink($path);
}
}
}
// close the directory
closedir($handle);
// return success
return TRUE;
}
}
How if change your zip file to this?
zipfile.zip
- file1.ext
- file2.ext
- file3.ext
myFolderi have thousands of image files that have keyword text for the name. i am trying to read from the list of images and upload the text into a dB field. the problem is that some of the text has utf8 characters like l’Été that show up like this ��t�
how can i read foreign characters so that the accents will insert into the dB field?
this is how im handling it now
function ListFiles($dir) {
if($dh = opendir($dir)) {
$files = Array();
$inner_files = Array();
while($file = readdir($dh)) {
if($file != "." && $file != ".." && $file[0] != '.') {
if(is_dir($dir . "/" . $file)) {
$inner_files = ListFiles($dir . "/" . $file);
if(is_array($inner_files)) $files = array_merge($files, $inner_files);
} else {
array_push($files, $dir . "/" . $file);//$dir = directory name
//array_push($files, $dir);
}
}
}
closedir($dh);
return $files;
}
}
foreach (ListFiles('../../myDirectory') as $key=>$file){
//$file = preg_replace( '#[^\0-\x80]#u',"", $file );
echo $file ."<br />";
}
this is producing the same result
$str = "l’Été";
utf8_decode($str);
echo $str;
This solution may work for you, it will loop through all files in a directoy and then recursivly through any directories found until it ends up with a massive array of files.
Ive added some points you may wish to change, eg either mutli or single dimension arrays ( all depend on if you may want to maintain the folder structure.
and also if you want the file extention to be saved when you save the file name to db.
Code
function recursive_search_dir($dir) {
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if (in_array($file,array(".","..")))
continue; // We dont want to do anything with parent / current directory.
if (is_dir($file)) {
$result[] = recursive_search_dir($file); // Multi-dimension
# OR
array_merge($result,recursive_search_dir($file));// Single-dimension if you dont care about folder structure.
} else {
$result[] = utf8_decode($file); // full file name ( includes extention )
# OR
$result[] = utf8_decode(filename($file,PATHINFO_FILENAME)); // if you only want to capture the name and not the extention.
}
}
closedir($handle);
}
return $result;
}
$files = recursive_search_dir("."); // recursively searcht the current directory.
This is the starting portion of my code to list files in a directory:
$files = scandir($dir);
$array = array();
foreach($files as $file)
{
if($file != '.' && $file != '..' && !is_dir($file)){
....
I'm trying to list all files in a directory without listing subfolders. The code is working, but showing both files and folders. I added !is_dir($file) as you see in my code above, but the results are still the same.
It should be like this, I think:
$files = scandir($dir);
foreach($files as $file)
{
if(is_file($dir.$file)){
....
Just use is_file.
Example:
foreach($files as $file)
{
if( is_file($file) )
{
// Something
}
}
This will scan the files then check if . or .. is in an array. Then push the files excluding . and .. in the new files[] array.
Try this:
$scannedFiles = scandir($fullPath);
$files = [];
foreach ($scannedFiles as $file) {
if (!in_array(trim($file), ['.', '..'])) {
$files[] = $file;
}
}
What a pain for something so seemingly simple! Nothing worked for me...
To get a result I assumed the file name had an extension which it must in my case.
if ($handle = opendir($opendir)) {
while (false !== ($entry = readdir($handle))) {
$pos = strpos( $entry, '.' );
if ($entry != "." && $entry != ".." && is_numeric($pos) ) {
............ good entry
Use the DIRECTORY_SEPARATOR constant to append the file to its directory path too.
function getFileNames($directoryPath) {
$fileNames = [];
$contents = scandir($directoryPath);
foreach($contents as $content) {
if(is_file($directoryPath . DIRECTORY_SEPARATOR . $content)) {
array_push($fileNames, $content);
}
}
return $fileNames;
}
This is a quick and simple one liner to list ONLY files. Since the user wants to list only files, there is no need to scan the directory and return all the contents and exclude the directories. Just get the files of any type or specific type. Use * to return all files regardless of extension or get files with a specific extension by replacing the * with the extension.
Get all files regardless of extension:
$files = glob($dir . DIRECTORY_SEPARATOR . "*");
Get all files with the php extension:
$files = glob($dir . DIRECTORY_SEPARATOR . "*.php");
Get all files with the js extension:
$files = glob($dir . DIRECTORY_SEPARATOR . "*.js");
I use the following for my sites:
function fileList(string $directory, string $extension="") :array
{
$filetype = '*';
if(!empty($extension) && mb_substr($extension, 0, 1, "UTF-8") != '.'):
$filetype .= '.' . $extension;
else:
$filetype .= $extension;
endif;
return glob($directory . DIRECTORY_SEPARATOR . $filetype);
}
Usage :
$files = fileList($configData->includesDirectory, '');
With my custom function, I can include an extension or leave it empty. Additionally, I can forget to place the . before the extension and it will succeed.
