Limit shown directories in PHP - php

How can I show a folder's limit in a directory using PHP? The code below shows all folders but I only want to see 10 folders.
function folderlist() {
$startdir = './';
$ignoredDirectory[] = '.';
$ignoredDirectory[] = '..';
if(is_dir($startdir)) {
if($dh = opendir($startdir)) {
while(($folder = readdir($dh)) !== false) {
if(!(array_search($folder, $ignoredDirectory) > -1)) {
if(filetype($startdir.$folder) == "dir") {
$mtime = filemtime($startdir.$folder);
$directorylist[$mtime]['name'] = $folder;
$directorylist[$mtime]['path'] = $startdir;
}
}
}
closedir($dh);
}
}
krsort($directorylist, SORT_NUMERIC);
return $directorylist;
}
$folders = folderlist();
foreach($folders as $folder) {
$path = $folder['path'];
$name = $folder['name'];
echo '<div class="urbangreymenu"><ul><li>'.$name.'</li></ul></div>';
}

Change three lines:
function folderlist($limit = 10) {
and ...
while (($folder = readdir($dh)) !== false && $limit) {
and...
$limit--;
Together:
function folderlist($limit = 10) {
$startdir = './';
$ignoredDirectory[] = '.';
$ignoredDirectory[] = '..';
if (is_dir($startdir)) {
if ($dh = opendir($startdir)) {
while (($folder = readdir($dh)) !== false && $limit) {
if (!(array_search($folder,$ignoredDirectory) > -1)) {
if (filetype($startdir . $folder) == "dir") {
$mtime = filemtime($startdir . $folder);
$directorylist[$mtime]['name'] = $folder;
$directorylist[$mtime]['path'] = $startdir;
$limit--;
}
}
}
//Rest of code unchanged...

Php add comand for search file on subfolders

I have this script that works good, but I need to add a command for searching on all subfolders.
Example: I have a folder data and this contains more another folders... I need to search files on this folders.
$dir = 'data';
$exclude = array('.', '..', '.htaccess');
$q = (isset($_GET['q'])) ? strtolower($_GET['q']) : '';
$res = opendir($dir);
while(false !== ($file = readdir($res))) {
if(strpos(strtolower($file), $q) !== false &&!in_array($file, $exclude)) {
echo "<a href='$dir/$file'>$file</a>";
echo "<br>";
}
}
closedir($res);
you can use scandir() function
$dir = '/tmp';
$file = scandir($dir);
print_r($file);
I think this is the recursive function you are looking for :
function dir_walk($dir, $q) {
$q = trim($q);
$exclude = array('.', '..', '.htaccess');
if($dh = opendir($dir)) {
while(($file = readdir($dh)) !== false) {
if(in_array($file, $exclude)) { continue; }
elseif(is_file($dir.$file)) {
if($q === '' || strpos(strtolower($file), $q) !== false) {
echo '<a href='.$dir.$file.'>'.$dir.$file.'</a><br/>';
}
}
elseif(is_dir($dir.$file)) {
dir_walk($dir.$file.DIRECTORY_SEPARATOR, $q);
}
}
closedir($dh);
}
}
$q = (isset($_GET['q'])) ? strtolower($_GET['q']) : '';
dir_walk('/data/', $q);
Edit: data need to be the absolute path to the main dir, with ending directory separator "/data/"

PHP absolute file

How do we return the absolute path of largest file in a particular directory?
I've been fishing around and haven't turned up anything concrete?
I'm thinking it has something to do with glob()?
$sz = 0;
$dir = '/tmp'; // will find largest for `/tmp`
if ($handle = opendir($dir)) { // will iterate through $dir
while (false !== ($entry = readdir($handle))) {
if(($curr = filesize($dir . '/' . $entry)) > $sz) { // found larger!
$sz = $curr;
$name = $entry;
}
}
}
echo $dir . '/' . $name; // largest
$dir = 'DIR_NAME';
$max_filesize = 0;
$path= '';
foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator(realpath($dir),FilesystemIterator::SKIP_DOTS)) as $file){
if ($file->getSize() >= $max_filesize){
$max_filesize = $file->getSize();
$path = $file->getRealPath(); // get absolute path
}
}
echo $path;
function getFileSize($directory) {
$files = array();
foreach (glob($directory. '*.*') as $file) {
$files[] = array('path' => $file, 'size' => filesize($file));
}
return $files;
}
function getMaxFile($files) {
$maxSize = 0;
$maxIndex = -1;
for ($i = 0; $i < count($files); $i++) {
if ($files[$i]['size'] > $maxSize) {
$maxSize = max($maxSize, $files[$i]['size']);
$maxIndex = $i;
}
}
return $maxIndex;
}
usage:
$dir = '/some/path';
$files = getFileSize($dir);
echo '<pre>';
print_r($files);
echo '</pre>';
$maxIndex = getMaxFile($files);
var_dump($files[$maxIndex]);

copy a php file to every directory

I've a simple problem of copying a a php folder to some directories, bu the problem is I can't the solution for that, the idea is that I've an Online Manga Viewer script, and what I want to do is I want to add comments page to every chapter, the I dea that I came with, is, I create a separate comments page file and once a new chapter added the the comments file will be copied to the folder of the chapter :
Description Image:
http://i.stack.imgur.com/4wYE0.png
What I to know is how can I do it knowing that I will use Disqus commenting System.

And thanks for all of you!
Include the following line in all of your pages in a small php statement, if it covers two folder paths, use this. Which I think in your case it does.
<?php
include('../../header.php');
?>
And then save this in the main root directory. Which in your diagram is called "Main Folder"

Read all files in directory except

The function below returns an array of XML files from a given directory including all subdirectories. How can I modify this function by passing a second optional parameter which excludes a directory.
E.g:
getDirXmlFiles($config_dir, "example2");
Directory/Files
/file1.xml
/file2.xml
/examples/file3.xml
/examples/file4.xml
/example2/file5.xml
/example2/file5.xml
In the above case the function would return all files except files in the example2 directory.
function getDirXmlFiles($base) {
$files = array();
if(!is_dir($base)) return $files;
if ($handle = opendir($base)) {
while (false !== ($file = readdir($handle))) {
if ($file == "." || $file == "..") continue;
if(is_dir("$base/$file")) {
$subfiles = $this->getDirXmlFiles("$base/$file");
$files = array_merge($files, $subfiles);
} else {
if(Cms_File::type($file,false) == "xml")
$files[] = "$base/$file";
}
}
closedir($handle);
}
return $files;
}
Try this:
function getDirXmlFiles($base, $exclude = NULL) {
$files = array();
if(!is_dir($base)) return $files;
if ($handle = opendir($base)) {
while (false !== ($file = readdir($handle))) {
if ($file == "." || $file == ".." || "$base/$file" == $exclude) continue;
if(is_dir("$base/$file")) {
$subfiles = $this->getDirXmlFiles("$base/$file",$exclude);
$files = array_merge($files, $subfiles);
} else {
if(Cms_File::type($file,false) == "xml")
$files[] = "$base/$file";
}
}
closedir($handle);
}
return $files;
}
Redefine the function inputs:
function getDirXmlFiles($base, $excludeDir) {
Then change this line:
if(is_dir("$base/$file")) {
to this:
if(is_dir("$base/$file") && "$base/$file" != "$base/$excludeDir") {
You can just slightly modify the function to check and see if the current directory is the one you want to exclude or not
function getDirXmlFiles($base,$exclude) {
$files = array();
if(!is_dir($base)) return $files;
if ($handle = opendir($base)) {
while (false !== ($file = readdir($handle))) {
if ($file == "." || $file == "..") continue;
if(is_dir("$base/$file") && $file != $exclude) {
$subfiles = $this->getDirXmlFiles("$base/$file",$exclude);
$files = array_merge($files, $subfiles);
} else {
if(Cms_File::type($file,false) == "xml")
$files[] = "$base/$file";
}
}
closedir($handle);
}
return $files;
}
Smth of the sort ( tested only the syntax validation there might be needed some small debugging ) ( this will allow you to exclude multiple directory names )
function getDirXmlFiles($base, $excludeArray = array()) {
if (!is_array($excludeArray))
throw new Exception(__CLASS__ . "->" . __METHOD__ . " expects second argument to be a valid array");
$files = array();
if(!is_dir($base)) return $files;
if ($handle = opendir($base)) {
while (false !== ($file = readdir($handle))) {
$path = $base . "/" . $file;
$isDir = is_dir($path);
if (
$file == "."
|| $file == ".."
|| (
$isDir
&& count($excludeArray) > 0
&& in_array($file, $excludeArray)
)
)
continue;
if($isDir) {
$subfiles = $this->getDirXmlFiles($path, $excludeArray);
$files = array_merge($files, $subfiles);
} else {
if(Cms_File::type($file,false) == "xml")
$files[] = $path;
}
}
closedir($handle);
}
return $files;
}

How to change a recursive function for count files and catalogues?

<?php
function scan_dir($dirname) {
$file_count = 0 ;
$dir_count = 0 ;
$dir = opendir($dirname);
while (($file = readdir($dir)) !== false) {
if($file != "." && $file != "..") {
if(is_file($dirname."/".$file))
++$file_count;
if(is_dir($dirname."/".$file)) {
++ $dir_count;
scan_dir($dirname."/".$file);
}
}
}
closedir($dir);
echo "There are $dir_count catalogues and $file_count files.<br>";
}
$dirname = "/home/user/path";
scan_dir($dirname);
?>
Hello,
I have a recursive function for count files and catalogues. It returns result for each catalogue.
But I need a common result. How to change the script?
It returns :
There are 0 catalogues and 3 files.
There are 0 catalogues and 1 files.
There are 2 catalogues and 14 files.
I want:
There are 2 catalogues and 18 files.
You could tidy up the code a lot with RecursiveDirectoryIterator.
$dirs = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator(dirname(__FILE__))
, TRUE);
$dirsCount = $filesCount = 0;
while ($dirs->valid()) {
if ($dirs->isDot()) {
$dirs->next();
} else if ($dirs->isDir()) {
$dirsCount++;
} else if ($dirs->isFile()) {
$filesCount++;
}
$dirs->next();
}
var_dump($dirsCount, $filesCount);
You can return values from each recursive call, and sum those and return back to its caller.
<?php
function scan_dir($dirname) {
$file_count = 0 ;
$dir_count = 0 ;
$dir = opendir($dirname);
$sub_count = 0;
while (($file = readdir($dir)) !== false) {
if($file != "." && $file != "..") {
if(is_file($dirname."/".$file))
++$file_count;
if(is_dir($dirname."/".$file)) {
++ $dir_count;
$sub_count += scan_dir($dirname."/".$file);
}
}
}
closedir($dir);
echo "There are $dir_count catalogues and $file_count files.<br>";
return $sub_count + $dir_count + $file_count;
}
$dirname = "/home/user/path";
echo "Total count is ". scan_dir($dirname);
?>
The code will give you the net count of every item.
With a simple modification. Just, for example, keep the counts in an array that you can return from the function to add up to the previous counts, like so:
<?php
function scan_dir($dirname) {
$count['file'] = 0;
$count['dir'] = 0;
$dir = opendir($dirname);
while (($file = readdir($dir)) !== false) {
if($file != "." && $file != "..") {
if(is_file($dirname."/".$file))
$count['file']++;
if(is_dir($dirname."/".$file)) {
$count['dir']++;
$counts = scan_dir($dirname."/".$file);
$count['dir'] += $counts['dir'];
$count['file'] += $counts['file'];
}
}
}
closedir($dir);
return $count;
}
$dirname = "/home/user/path";
$count = scan_dir($dirname);
echo "There are $count[dir] catalogues and $count[file] files.<br>";
?>
In my opnion, you should separate counting file & counting dir to 2 different function. It will clear things up:
<?php
function scan_dir_for_file($dirname) {
$file_count = 0 ;
$dir = opendir($dirname);
while (($file = readdir($dir)) !== false) {
if($file != "." && $file != "..") {
if(is_file($dirname."/".$file))
{
++$file_count;
} else {
$file_count = $file_count + scan_dir($dirname."/".$file);
}
}
}
return $file_count
}
?>
The directory_count function is similar.
