I'm trying to list files in a folder. I have done this before, so I am not sure why I am having a problem now.
I have a PDF files I am trying to display to my web page. The directory structure looks like this:
folder1/folder2/displayFiles.php
folder1/folder2/files.pdf
displayFiles.php is the process file where I am using the code below.
I am trying to display the file called files.pdf onto the page, which is in the same directory as the process file.
Here is my code so far:
<?php
$dir = "folder1/folder2/";
// $dir = "/"; <-- I also tried this
$ffs = scandir($dir);
foreach($ffs as $ff)
{
if($ff != '.' && $ff != '..')
{
$filesize = filesize($dir . '/' . $ff);
echo "<ul><li><a download href='$dir/$ff'>$ff</a></li></ul>";
}
}
?>
I know it's a simple fix. I just cannot find the code to fix it.
Your $dir is pointing at a non-existent folder
Change the dir to point to the folder correctly $dir = ".";.
Just use glob
http://php.net/manual/de/function.glob.php
$pdfs = glob("*.pdf"); // if needed loop through your directorys and glob files
print_r($pdfs);
Just an example. You should be able to use it with some edits.

I need a little bit of help. I need to write a script that will look through all directories and sub-directories and delete specific extensions that are modified after specific time. I can get it to delete files from specific path, but I need the script to search inside sub directories. Is there any way to do that?
I have tried this for files but I have no idea on how to make it work with directories and sub directories
$path = '/path/to/file/';
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle))) {
$filelastmodified = filemtime($path . $file);
if( $filelastmodified > "MY TIME STAMP" )
{
unlink($path . $file);
}
echo "deleted";
}
closedir($handle);
}
Create a recursive function, if it finds a folder it calls itself passing the folder name.
I have these files in /public_html/ directory :
0832.php
1481.php
2853.php
3471.php
index.php
and I want to move all those XXXX.php (always in 4 digits format) to directory /tmp/, except index.php. how to do it with reg-ex and loop?
Alternatively, how about moving all files (including index.php) first to /tmp/ then later on put only index.php back to /public_html/, which one you think is less CPU consuming?
Last thing, I found this tutorial to move file using PHP: http://www.kavoir.com/2009/04/php-copying-renaming-and-moving-a-file.html
But how to move ALL files in a directory?
You can use FilesystemIterator with RegexIterator
$source = "FULL PATH TO public_html";
$destination = "FULL PATH TO public_html/tmp";
$di = new FilesystemIterator($source, FilesystemIterator::SKIP_DOTS);
$regex = new RegexIterator($di, '/\d{4}\.php$/i');
foreach ( $regex as $file ) {
rename($file, $destination . DIRECTORY_SEPARATOR . $file->getFileName());
}
The best way would be to do it directly via the file system, but if you absolutely have to do it with PHP, something like this should do what you want - you'll have to change the paths so that they are correct, obviously. Note that this assumes that there could be other files in the public_html directory, and so it only get the filenames with 4 numbers.
$d = dir("public_html");
while (false !== ($entry = $d->read())) {
if($entry == '.' || $entry == '..') continue;
if(preg_match("#^\d{4}$#", basename($entry, ".php")) {
// move the file
rename("public_html/".$entry, "/tmp/".$entry));
}
}
$d->close();
in fact - I went to readdir manual page and the fist comment to read is:
loop through folders and sub folders with option to remove specific files.
<?php
function listFolderFiles($dir,$exclude){
$ffs = scandir($dir);
echo '<ul class="ulli">';
foreach($ffs as $ff){
if(is_array($exclude) and !in_array($ff,$exclude)){
if($ff != '.' && $ff != '..'){
if(!is_dir($dir.'/'.$ff)){
echo '<li>'.$ff.'';
} else {
echo '<li>'.$ff;
}
if(is_dir($dir.'/'.$ff)) listFolderFiles($dir.'/'.$ff,$exclude);
echo '</li>';
}
}
}
echo '</ul>';
}
listFolderFiles('.',array('index.php','edit_page.php'));
?>
Regexes are in fact overkill for this, as we only need to do some simple string matching:
$dir = 'the_directory/';
$handle = opendir($dir) or die("Problem opening the directory");
while ($filename = readdir($handle) !== false)
{
//if ($filename != 'index.php' && substr($filename, -3) == '.php')
// I originally thought you only wanted to move php files, but upon
// rereading I think it's not what you really want
// If you don't want to move non-php files, use the line above,
// otherwise the line below
if ($filename != 'index.php')
{
rename($dir . $filename, '/tmp/' . $filename);
}
}
Then for the question:
alternatively, how about moving all files (including index.php) first to /tmp/ then later on put only index.php back to /public_html/, which one you think is less CPU consuming?
It could be done, and it would probably be slightly easier on your CPU. However, there are several reasons why this doesn't matter. First off, you're already doing this in a very inefficient way by doing it through PHP, so you shouldn't really be looking at the strain this puts on your CPU at this point unless you are willing to do it outside PHP. Secondly, that would cause more disk access (especially if the source and destination directory aren't on the same disk or partition) and disk access is much, much slower than your CPU.
(Well what I gone through a lot of posts here on stackoverflow and other sites. I need a simple task, )
I want to provide my user facility to click on upload file from his account, then select a directory and get the list of all the files names inside that directory.
According to the posts here what I got is I have to pre-define the directory name, which I want to avoid.
Is there a simple way to click a directory and get all the files names in an array in PHP? many thanks in advance!
$dir = isset($_POST['uploadFile']) ? _SERVER['DOCUMENT_ROOT'].'/'.$_POST['uploadFile'] : null;
if ($_POST['uploadFile'] == true)
{
foreach (glob($dir."/*.mp3") as $filename) {
echo $filename;
}
}
I will go ahead and post a sample of code I am currently using, with a few changes, although I would normally tell you to look it up on google and try it first.
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
echo $file;
}
closedir($handle);
}
This will display the entire contents of a directory... including: ".", "..", any sub-directories, and any hidden files. I am sure you can figure out a way to hide those if it is not desirable.
<?php
$files=glob("somefolder/*.*");
print_r($files);
?>
Take a look at the Directory class (here) and readdir()
I'm confused what do you want, all files or only some files?
But if you want array of folders and files, do this
$folders = array();
$files = array();
$dir = opendir("path");
for($i=0;false !== ($file = readdir($dir));$i++){
if($file != "." and $file != ".."){
if(is_file($file)
$files[] = $file;
else
$folders[] = $file;
}
}
And if only some folders you want, later you can delete them from array
I always use this amazing code to get file lists:
$THE_PATTERN=$_SERVER["DOCUMENT_ROOT"]."/foldername/*.jpg";
$TheFilesList = #glob($THE_PATTERN);
$TheFilesTotal = #count($TheFilesList);
$TheFilesTotal = $TheFilesTotal - 1;
$TheFileTemp = "";
for ($TheFilex=0; $TheFilex<=$TheFilesTotal; $TheFilex++)
{
$TheFileTemp = $TheFilesList[$TheFilex];
echo $TheFileTemp . "<br>"; // here you can get full address of files (one by one)
}
$value can = a folder structure to the language file. Example: languages/english.php
$value can also = the files name. Example: english.php
So I need to get the current folder that $value is in and delete the folder ONLY if there are no other files/folders within that directory (after deleting the actual file as I am doing already, ofcourse).
foreach($module['languages'] as $lang => $langFile)
{
foreach ($langFile as $type => $value)
{
#unlink($module_path . '/' . $value);
// Now I need to delete the folder ONLY if there are no other directories inside the folder where it is currently at.
// And ONLY if there are NO OTHER files within that folder also.
}
}
How can I do this?? And wondering if this can be done without using a while loop, since a while loop within a foreach loop could take some time, and need this to be as quick as possible.
And just FYI, the $module_path should never be deleted. So if $value = english.php, it should never delete the $module_path. Ofcourse, there will always be another file in there, so checking for this is not necessary, but won't hurt either way.
Thanks guys :)
EDIT
Ok, now I'm using this code here and it is NOT working, it is not removing the folders or the files, and I don't get any errors either... so not sure what the problem is here:
foreach($module['languages'] as $lang => $langFile)
{
foreach ($langFile as $type => $value)
{
if (#unlink($module_path . '/' . $value))
#rmdir(dirname($module_path . '/' . $value));
}
}
NEVERMIND, this works a CHARM!!! Cheers Everyone!!
The easyest way is try to use rmdir. This don't delete folder if it is not empty
rmdir($module_path);
also you can check is folder empty by
if(count(glob($module_path.'*'))<3)//delete
2 for . and ..
UPD: as I reviewed maybe you should replace $module_path by dirname($module_path.'.'.$value);
Since the directory you care about might be part of the $value, you need to use dirname to figure out what the parent directory is, you can't just assume that it's $module_path.
$file_path = $module_path . '/' . $value;
if (#unlink($file_path)) {
#rmdir(dirname($file_path));
}
if (is_file($value)) {
unlink($value);
} else if (is_dir($value)) {
if (count(scandir($value)) == 2) }
unlink($value)
}
}

The code below will take a path, check if it is a file (i.e. not a directory). If it is a file, it will extract the directory name, then delete the file, then iterate over the dir and count the files in it, if the files are zero it'll delete the dir.
Code is as an example and should work, however privileges and environment setup may result in it not working.
<?php
if(!is_dir ( string $filename )){ //if it is a file
$fileDir = dirname ( $filename );
if ($handle = opendir($fileDir)) {
echo "Directory handle: $handle\n";
echo "Files:\n";
$numFiles=0;
//delete the file
unlink($myFile);
//Loop the dir and count the file in it
while (false !== ($file = readdir($handle))) {
$numFiles = $numFiles + 1;
}
if($numFiles == 0) {
//delete the dir
rmdir($fileDir);
}
closedir($handle);
}
}
?>
I want to move all files from one folder to other. my code is as following. in this I made a folder in which i want to copy all file from templats folder
$doit = str_replace(" ", "", $slt['user_compeny_name']);
mkdir("$doit");
$source = "templat/";
$target = $doit . "/";
$dir = opendir($source);
while (($file = readdir($dir)) !== false) {
copy($source . $file, $target . $file);
}
It working fine . copy all files but give warning that The first argument to copy() function cannot be a directory
can any one help me asap
Readdir will read all children in a directory, including other dirs, and 'virtual' dirs like . and .. (link to root and parent dir, resp.) You'll have to check for these and prevent the copy() function for these instances.
while (($file = readdir($dir)) !== false)
{
if(!is_dir($file))
{
copy($source.$file, $target.$file);
}
}
You are not accounting for the . and the .. files at the top of the directory. This means that the first thing it tries to copy is "\template." which would be the same as trying to copy the directory.
Just add something like:
if ($file !== "." && $file !== "..")
...
opendir() will include items . and .. as per the documentation.
You will need to exclude these by using the code in the other comments.
if ($file != "." && $file != "..") {
// copy
}
I know, this question is pretty old, but also are the answers. I feel the need to show some new methods, which can be used to execute the requested task.
In the mean time Objects were introduced with a lot more features and possibilities. Needless to say, the other answers will still work aswell.
But here we go, using the DirectoryIterator:
$szSrcFolder = 'source_folder';
$szTgtFolder = 'target_folder';
foreach (new DirectoryIterator($szSrcFolder) as $oInfo)
if ($oInfo->isFile())
copy($oInfo->getPathname(), $szTgtFolder . DIRECTORY_SEPARATOR . $oInfo->getBasename());
Remember, within this script, all paths are relative to the working directory of the script itself.
I think it is self explaining, but we will take a look. This few lines will iterate over the whole content of the source folder and check if it is a file and will copy it to the target folder, keeping the original file name.
