My directory structure is like D:/dir1/dir2/project_dir/dir3/dir4/dir5/cache/all_files
So i want to get all the files under cache folder.
So i wrote
glob("project_dir/*/*/*/cache/*");
But cache folder is also there in dir3 or dir4 like
D:/dir1/dir2/project_dir/dir3/dir4/dir5/dir6/dir7/cache/all_files
or
D:/dir1/dir2/project_dir/dir3/cache/all_files
So can anyone give me the regex to get the files from 'cache' folder,
like
glob("project_dir/*/cache/*");
Btw, this is not working because it is searching for immediate directory after project_dir.
Thanks in advance.
Hope this helps!
Supports PHP 5 and 7 only,check your version before using this code
for more info refer : http://php.net/manual/en/class.directoryiterator.php
$searchCacheFolderUnder = 'D:\xampp\htdocs\mygit\\';
$pathOfAllCacheFolders = array();
$dir = new DirectoryIterator(realpath($searchCacheFolderUnder));
foreach ($dir as $fileInfo) {
if($fileInfo->isDir()) {
// optimize strpos with inbuild directory iterator methods
if( strpos($fileInfo->getPathname(), 'cache') !== false ){
$pathOfAllCacheFolders[] = $fileInfo->getPathname();
}
}
}
// contains all cache folders path
echo "<pre>";
print_r($pathOfAllCacheFolders);
echo "</pre>";
// loop on all cache folders
foreach($pathOfAllCacheFolders as $cachePath)
$dirCache = new DirectoryIterator(realpath($cachePath));
foreach ($dirCache as $fileInfo) {
//$fileInfo object will have everything you need
echo "<pre>";
print_r($fileInfo);
echo "</pre>";
}
You have to modify this code a bit to meet your requirement. Refer Directory Iterator for more available options.
You can use glob('*') but the only perk for using this is it ignores all hidden files. If you want all the files that includes hidden files in a folder then use:
$files = glob('project_dir/cache/{,.}*', GLOB_BRACE);
Remember this will return all the files for "." and "" and even the directory entries . and .. Let me know in case of any issues.
Hope this helps.

So I have a URL which contains &title=blabla
I know how to extract the title, and return it. But I've been searching my ass off to get the full path to the filename when I only have the filename.
So what I must have is an way to search in all directories for an html file called 'blabla' when the only thing it has is blabla. After finding it, it must return the full path.
Anyone who does have an solution for me?
<?php
$file = $_GET['title'];
if ($title = '') {
echo "information.html";
} else {
//here it must search for the filepath and echo it.
echo "$filepath";
}
?>
You can use the solution provided here.
It allows you to recurse through a directory and list all files in the directory and sub-directories. You can then compare to see if it matches the files you are looking for.
$root = '/'; // directory from where to start search
$toSearch = 'file.blah'; // basename of the file you wish to search
$it = new RecursiveDirectoryIterator($root);
foreach(new RecursiveIteratorIterator($it) as $file){
if($file->getBasename() === $toSearch){
printf("Found it! It's %s", $file->getRealPath());
// stop at the first match
break;
}
}
Keep in mind that depending on the number of files you have, this can be slow as hell
For a start this line is at fault
if ($title = '') {
See http://www.php.net/manual/en/reserved.variables.files.php
I've been trying to make a simple website that lets you specify a directory, and embeds a player for each mp3 in whatever directory the user specifies. The problem is that no matter how I enter the directory name, glob() does not return any files. I've tried this with local folders, server directories, and the same folder as the php file.
'directoryPath' is the name of the text box where the user enters, you guessed it, the directory path. The 'echo $files' statement displays nothing onscreen. The 'echo "test"' statement DOES run, but the 'echo "hello"' statement in the loop does not execute.
Any help is appreciated!
if (!empty($_POST['directoryPath']))
{
$path = ($_POST['directoryPath']);
$files = glob("$path/{*.mp3}", GLOB_BRACE);
echo $files[0];
echo "test";
foreach($files as $i)
{
echo "hello";
echo $files[$i];
?>
<embed src=<?php $files[$i]; ?> width=256 height=32 autostart=false repeat=false loop=false></embed><?php echo $files[$i] ?></p>
<?php;
}
unset($i);
}
Validate the input first:
$path = realpath($_POST['directoryPath']);
if (!is_dir($path)) {
throw new Exception('Invalid path.');
}
...
Additionally check the return value glob returns false on error. Check for that condition (and ensure you are not using one of those systems that even return false when there are no files found).
I hope this is helpful. And yes, check your error log and enable error logging. This is how you can see what is going wrong.
Also see the following related function for a usage-example and syntax of GLOB_BRACE:
Running glob() from an included script returns empty array
One one tool I find very useful in helping debug variables in PHP is var_dump(). It's a function that provides you with information about a variable's type, it's contents, and any useful metadata it can attain from that variable. This would be a very useful tool for you here, because you'll quickly realize what you have in the variable $i is not at all what you expect.
$files = glob("$path/{*.mp3}", GLOB_BRACE);
foreach ($files as $i) {
var_dump($i);
}
/* Here's a hint, $i is not an index to the $files array.
So $files[$i] makes no sense. $i is actually the value not the key.*/
foreach ($files as $key => $value) { // very different from
// $key is the key to the current element of $files we're iterating over
// $value is the value of the current element we're iterating over
}
So in your code $i is the value not the key. See http://php.net/foreach for more information on how the construct works.
Also, what should be noted here is that you are using a relative path, whereas glob will return an absolute path. By relative this means your searching relative to the CWD (Current Working Directory) of your PHP script. To see wha that is you can use the following code.
var_dump(real_path('.'));
// similarly ...
var_dump(getcwd());

PHP list of specific files in a directory
use php scandir($dir) and get only images!
So right now I have a directory and I am getting a list of files

PHP has a great function to help you capture only the files you need. Its called glob()
glob - Find pathnames matching a pattern
Returns an array containing the matched files/directories, an empty array if no file matched or FALSE on error.
Here is an example usage -
$files = glob("/path/to/folder/*.txt");
This will populate the $files variable with a list of all files matching the *.txt pattern in the given path.
Reference -
glob()
If you want more than one extension searched, then preg_grep() is an alternative for filtering:
$files = preg_grep('~\.(jpeg|jpg|png)$~', scandir($dir_f));
Though glob has a similar extra syntax. This mostly makes sense if you have further conditions, add the ~i flag for case-insensitive, or can filter combined lists.
PHP's glob() function let's you specify a pattern to search for.
You can try using GlobIterator
$iterator = new \GlobIterator(__DIR__ . '/*.txt', FilesystemIterator::KEY_AS_FILENAME);
$array = iterator_to_array($iterator);
var_dump($array);
glob($pattern, $flags)
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename size " . filesize($filename) . "\n";
}
?>
try this
//path to directory to scan
$directory = "../file/";
//get all image files with a .txt extension.
$file= glob($directory . "*.txt ");
//print each file name
foreach($file as $filew)
{
echo $filew;
$files[] = $filew; // to create the array
}
haven't tested the regex but something like this:
if ($handle = opendir('/file/path')) {
while (false !== ($entry = readdir($handle))) {
if (preg_match('/\.txt$/', $entry)) {
echo "$entry\n";
}
}
closedir($handle);
}
I have a double question. Part one: I've pulled a nice list of pdf files from a directory and have appended a file called download.php to the "href" link so the pdf files don't try to open as a web page (they do save/save as instead). Trouble is I need to order the pdf files/links by date created. I've tried lots of variations but nothing seems to work! Script below. I'd also like to get rid of the "." and ".." directory dots! Any ideas on how to achieve all of that. Individually, these problems have been solved before, but not with my appended download.php scenario :)
<?php
$dir="../uploads2"; // Directory where files are stored
if ($dir_list = opendir($dir))
{
while(($filename = readdir($dir_list)) !== false)
{
?>
<p><a href="http://www.duncton.org/download.php?file=login/uploads2/<?php echo $filename; ?>"><?php echo $filename;
?></a></p>
<?php
}
closedir($dir_list);
}
?>
While you can filter them out*, the . and .. handles always come first. So you could just cut them away. In particular if you use the simpler scandir() method:
foreach (array_slice(scandir($dir), 2) as $filename) {
One could also use glob("dir/*") which skips dotfiles implicitly. As it returns the full path sorting by ctime then becomes easier as well:
$files = glob("dir/*");
// make filename->ctime mapping
$files = array_combine($files, array_map("filectime", $files));
// sorts filename list
arsort($files);
$files = array_keys($files);
