I have a lot of subfolders that have spaces in their names (in this example under main folder TEMP, could be folders "folder A" "folder B has many spaces" etc. I have tried this code to replace all sub folder names spaces with underlines but could someone please tell me why it isn't working?
Cheers.
<?php
$dir = 'https://www.example.com/image/catalog/TEMP';
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($foldername = readdir($dh)) !== false) {
rename($dir.$foldername, str_replace(" ","_",$dir.$foldername));
}
closedir($dh);
}
}
?>
Keep in mind You cannot list directories by URL and rename them.
So please write at least relative path.
For example if script at root of www:
$dir = __DIR__ . DS . 'image/catalog/TEMP';
<?php
const DS = DIRECTORY_SEPARATOR;
$dir = __DIR__ . DS . 'image/catalog/TEMP';
if (!is_dir($dir)) {
echo "\n".$dir." is not directory"."\n";
exit(0);
}
$dh = opendir($dir);
while ($item = readdir($dh)) :
if ($item === '.' || $item === '..') continue;
$current = $dir . DS . $item;
$new = $dir . DS . str_replace(" ", "_", $item);
if ($current === $new) continue; // nothing to rename
rename($current, $new);
echo $current.' => '.$new."\n";
endwhile;
closedir($dh);

The following code successfully removes sub directories and the files within them.
However it also removes all files in the directory above what is specified as $dir. This is not desired.
Can anybody see what is wrong with the code?
private function unlinkPubDirectory()
{
$dir = DIR_DOWNLOAD_PUB;
$h1 = opendir($dir);
while ($subdir = readdir($h1)) {
$h2 = opendir($dir . $subdir);
while ($file = readdir($h2)) {
#unlink($dir . $subdir . '/' . $file);
}
closedir($h2);
#rmdir($dir . $subdir);
}
closedir($h1);
}
As marked in the comments you should check for '..' as a possible file/directory and omit it. Additionally, check for errors without the '#'-sign.
private function unlinkPubDirectory()
{
$dir = DIR_DOWNLOAD_PUB;
$h1 = opendir($dir);
while ($subdir = readdir($h1)) {
if ($subdir == '..') continue; // don't do anything with '..'
$h2 = opendir($dir . $subdir);
while ($file = readdir($h2)) {
unlink($dir . $subdir . '/' . $file);
}
closedir($h2);
rmdir($dir . $subdir);
}
closedir($h1);
}
This will show you what is being deleted
while ($subdir = readdir($h1)) {
$h2 = opendir($dir . $subdir);
while ($file = readdir($h2)) {
echo "<p>will remove file " . ($dir . $subdir . '/' . $file);
}
closedir($h2);
echo "<p>will remove dir " . ($dir . $subdir);
}
HINT: check for . or .. folders and ignore them
I'm new to PHP and i was just wondering if someone could help. I want my code to read files from a directory/sub directory and display all of them by the date they were modified! My code displays only one file, which is the one that I recently changed. So how do I list all the files? I hope this question makes some sense..
<?php
$last_mtimes = array();
function ListFiles($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);
$lmtime = filemtime($dir . "/" . $file) ;
$last_mtimes[$lmtime] = $dir . "/" . $file;
}
}
}
krsort($last_mtimes);
closedir($dh);
return ($last_mtimes);
}
}
foreach (ListFiles('folder/folder/') as $key=>$file);
echo array_shift(ListFiles('folder/folder/'));
?>
There is an extra semi colon which makes the loop do nothing:
foreach (ListFiles('folder/folder/') as $key=>$file);

I have a folder on my server called 'images', and within that folder I could have a single folder to as many as 10 folders that contain images.
Instead of writing a tag for each image
<img src="images/people/001.jpg">
<img src="images/landscape/001.jpg">
etc etc
Can I use PHP to get all the images in all the folders in the main directory 'images'?
I have VERY little experience with PHP, so this is something I am struggling with.
I need php to return an array of '<div class="box"><img src="images/FOLDER/IMAGENAME.jpg"></div>'
Maybe someone can help.
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 . "/" . $file);
}
}
}
closedir($dh);
return $files;
}
}
foreach (ListFiles('/path/to/images') as $key=>$file){
echo "<div class=\"box\"><img src=\"$file\"/></div>";
}
Something like this?
A simpler soluton. You can use built-in glob function. Assuming that all of your images are .jpg:
$result = array();
$dir = 'images/';
foreach(glob($dir.'*.jpg') as $filename) {
$result[] = "<div class=\"box\"><img src=\"$filename\"></div>";
}
Then you can echo each element of $result or whatever you want.

Getting the names of all files in a directory with PHP
(15 answers)
Closed 6 months ago.
I have the code below that lists all the images in a folder, the problem is that it finds some files ( a . and a ..) that I am not sure what they are so I am not sure how to prevent them from showing up. I am on a windows XP machine, any help would be great, thanks.
Errors: Warning: rename(images/.,images/.) [function.rename]: No error
in C:\wamp\www\Testing\listPhotosA.php on line 14
Warning: rename(images/..,images/..) [function.rename]: No error in
C:\wamp\www\Testing\listPhotosA.php on line 14
Code:
<?php
define('IMAGEPATH', 'images/');
if (is_dir(IMAGEPATH)){
$handle = opendir(IMAGEPATH);
}
else{
echo 'No image directory';
}
$directoryfiles = array();
while (($file = readdir($handle)) !== false) {
$newfile = str_replace(' ', '_', $file);
rename(IMAGEPATH . $file, IMAGEPATH . $newfile);
$directoryfiles[] = $newfile;
}
foreach($directoryfiles as $directoryfile){
if(strlen($directoryfile) > 3){
echo '<img src="' . IMAGEPATH . $directoryfile . '" alt="' . $directoryfile . '" /> <br>';
}
}
closedir($handle); ?>
I like PHP's glob function.
foreach(glob(IMAGEPATH.'*') as $filename){
echo basename($filename) . "\n";
}
glob() is case sensitive and the wildcard * will return all files, so I specified the extension here so you don't have to do the filtering work
$d = 'path/to/images/';
foreach(glob($d.'*.{jpg,JPG,jpeg,JPEG,png,PNG}',GLOB_BRACE) as $file){
$imag[] = basename($file);
}
Use glob function.
<?php
define('IMAGEPATH', 'images/');
foreach(glob(IMAGEPATH.'*') as $filename){
$imag[] = basename($filename);
}
print_r($imag);
?>
You got all images in array format
To get all jpg images in all dirs and subdirs inside a folder:
function getAllDirs($directory, $directory_seperator) {
$dirs = array_map(function ($item) use ($directory_seperator) {
return $item . $directory_seperator;
}, array_filter(glob($directory . '*'), 'is_dir'));
foreach ($dirs AS $dir) {
$dirs = array_merge($dirs, getAllDirs($dir, $directory_seperator));
}
return $dirs;
}
function getAllImgs($directory) {
$resizedFilePath = array();
foreach ($directory AS $dir) {
foreach (glob($dir . '*.jpg') as $filename) {
array_push($resizedFilePath, $filename);
}
}
return $resizedFilePath;
}
$directory = "C:/xampp/htdocs/images/";
$directory_seperator = "/";
$allimages = getAllImgs(getAllDirs($directory, $directory_seperator));
Using balphp's scan_dir function:
https://github.com/balupton/balphp/blob/765ee3cfc4814ab05bf3b5512b62b8b984fe0369/lib/core/functions/_scan_dir.funcs.php
scan_dir($dirPath, array('pattern'=>'image'));
Will return an array of all files that are images in that path and all subdirectories, using a $path => $filename structure. To turn off scanning subdirectories, set the recurse option to false
Please use the following code to read images from the folder.
function readDataFromImageFolder() {
$imageFolderName = 14;
$base = dirname(__FILE__);
$dirname = $base.DS.'images'.DS.$imageFolderName.DS;
$files = array();
if (!file_exists($dirname)) {
echo "The directory $dirname not exists.".PHP_EOL;
exit;
} else {
echo "The directory $dirname exists.".PHP_EOL;
$dh = opendir( $dirname );
while (false !== ($filename = readdir($dh))) {
if ($filename === '.' || $filename === '..') continue;
$files[] = $dirname.$filename;
}
uploadImages( $files );
}
}

You can use OPP oriented DirectoryIterator class.
foreach (new DirectoryIterator(IMAGEPATH) as $fileInfo) {
// Removing dots
if($fileInfo->isDot()) {
continue;
}
// You have all necessary data in $fileInfo
echo $fileInfo->getFilename() . "<br>\n";
}
while (($file = readdir($handle)) !== false) {
if (
($file == '.')||
($file == '..')
) {
continue;
}
$newfile = str_replace(' ', '_', $file);
rename(IMAGEPATH . $file, IMAGEPATH . $newfile);
$directoryfiles[] = $newfile;
}
I need to create a loop through all files in subdirectories. Can you please help me struct my code like this:
$main = "MainDirectory";
loop through sub-directories {
loop through filels in each sub-directory {
do something with each file
}
};
Use RecursiveDirectoryIterator in conjunction with RecursiveIteratorIterator.
$di = new RecursiveDirectoryIterator('path/to/directory');
foreach (new RecursiveIteratorIterator($di) as $filename => $file) {
echo $filename . ' - ' . $file->getSize() . ' bytes <br/>';
}
You need to add the path to your recursive call.
function readDirs($path){
$dirHandle = opendir($path);
while($item = readdir($dirHandle)) {
$newPath = $path."/".$item;
if(is_dir($newPath) && $item != '.' && $item != '..') {
echo "Found Folder $newPath<br>";
readDirs($newPath);
}
else{
echo ' Found File or .-dir '.$item.'<br>';
}
}
}
$path = "/";
echo "$path<br>";
readDirs($path);
You probably want to use a recursive function for this, in case your sub directories have sub-sub directories
$main = "MainDirectory";
function readDirs($main){
$dirHandle = opendir($main);
while($file = readdir($dirHandle)){
if(is_dir($main . $file) && $file != '.' && $file != '..'){
readDirs($file);
}
else{
//do stuff
}
}
}
didn't test the code, but this should be close to what you want.
I like glob with it's wildcards :
foreach (glob("*/*.txt") as $filename) {
echo "$filename\n";
}
Details and more complex scenarios.
But if You have a complex folders structure RecursiveDirectoryIterator is definitively the solution.
Come on, first try it yourself!
What you'll need:
scandir()
is_dir()
and of course foreach
http://php.net/manual/en/function.is-dir.php
http://php.net/manual/en/function.scandir.php
Another solution to read with sub-directories and sub-files (set correct foldername):
<?php
$path = realpath('samplefolder/yorfolder');
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
{
echo "$filename <br/>";
}
?>
Minor modification on what John Marty posted, if we can safely eliminate any items that are named . or ..

if (($item == '.') || ($item == '..')) {
