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); ?>

Answer 1

I like PHP's glob function.
foreach(glob(IMAGEPATH.'*') as $filename){
echo basename($filename) . "\n";
}

Answer 2

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);
}

Answer 3

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

Answer 4

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));

Answer 5

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

Answer 6

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";
}

Answer 8

while (($file = readdir($handle)) !== false) {
if (
($file == '.')||
($file == '..')
) {
continue;
}
$newfile = str_replace(' ', '_', $file);
rename(IMAGEPATH . $file, IMAGEPATH . $newfile);
$directoryfiles[] = $newfile;
}
