I have this code:
<?php
$allowed = array('file1', 'file2', 'file3');
if (in_array($_GET["url"], $allowed)) {
// You can include
} else {
// Error message and dont include
}
?>
But instead of writing all the filenames in the array, how can i do so that the files in for example my folder FILES/ is accepted an no other files. How to do that?
Use the file_exists function like this:
if (file_exists('FILES/'.basename($_GET["url"]))) {
// You can include
} else {
// Error message and dont include
}
Function to retrieve files in a folder:
<?
function fGetFilesInFolder($sFolder) {
$aFiles = array();
if(file_exists($sFolder)) {
if ($handle = opendir($sFolder)) {
while (false !== ($sFile = readdir($handle))) {
if ($sFile != "." && $sFile != "..") $aFiles[] = $sFile;
}
closedir($handle);
}
}
return $aFiles;
}
?>

trying to find a way to copy entire directory but exclude certain files, in this case just need to exclude a directory which will always contain just 1 file a png... figured could use something similar to this code but have absolutely no clue as to how to exclude a file only
function xcopy($source, $dest, $permissions = 0755)
{
// Check for symlinks
if (is_link($source)) {
return symlink(readlink($source), $dest);
}
// Simple copy for a file
if (is_file($source)) {
return copy($source, $dest);
}
// Make destination directory
if (!is_dir($dest)) {
mkdir($dest, $permissions);
}
// Loop through the folder
$dir = dir($source);
while (false !== $entry = $dir->read()) {
// Skip pointers
if ($entry == '.' || $entry == '..') {
continue;
}
// Deep copy directories
xcopy("$source/$entry", "$dest/$entry", $permissions);
}
// Clean up
$dir->close();
return true;
}
Here is a function that may work for you. I have notated for clarification:
<?php
function CopyDirectory($settings = false)
{
// The script may take some time if there are lots of files
ini_set("max_execution_time",3000);
// Just do some validation and pre-sets
$directory = (isset($settings['dir']) && !empty($settings['dir']))? $settings['dir'] : false;
$copyto = (isset($settings['dest']) && !empty($settings['dest']))? $settings['dest'] : false;
$filter = (isset($settings['filter']) && !empty($settings['filter']))? $settings['filter'] : false;
// Add the copy to destinations not to copy otherwise
// you will have an infinite loop of files being copied
$filter[] = $copyto;
// Stop if the directory is not set
if(!$directory)
return;
// Create a recursive directory iterator
$dir = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory),RecursiveIteratorIterator::CHILD_FIRST);
try{
foreach($dir as $file) {
$copydest = str_replace("//","/",$copyto."/".str_replace($_SERVER['DOCUMENT_ROOT'],"",$file));
$compare = rtrim($file,".");
if(is_dir($file)) {
if(!is_dir($copydest)) {
if(!in_array($compare,$filter)) {
if(isset($skip) && !preg_match("!".$skip."!",$file) || !isset($skip))
#mkdir($copydest,0755,true);
else
$record[] = $copydest;
}
else {
$skip = $compare;
}
}
}
elseif(is_file($file) && !in_array($file,$filter)) {
copy($file,$copydest);
}
else {
if($file != '.' && $file != '..')
$record[] = $copydest;
}
}
}
// This will catch errors in copying (like permission errors)
catch (Exception $e)
{
$error[] = $e;
}
}
// Copy from
$settings['dir'] = $_SERVER['DOCUMENT_ROOT'];
// Copy to
$settings['dest'] = $_SERVER['DOCUMENT_ROOT']."/tester";
// Files and folders to not include contents
$settings["filter"][] = $_SERVER['DOCUMENT_ROOT'].'/core.processor/';
$settings["filter"][] = $_SERVER['DOCUMENT_ROOT'].'/config.php';
$settings["filter"][] = $_SERVER['DOCUMENT_ROOT'].'/client_assets/images/';
// Create instance
CopyDirectory($settings);
?>
I am trying to make codeigniter delete a product image folder.
Furthermore, the delete function I am trying to make needs to delete also all of its contents, so empty or not, the folder gets deleted. I'm guessing, it would use a recursive type of deletion...I'm not so sure at all.
I have tried the below functions for deleting :
function delete_directory($path)
{
$path=base_url().'products/thumb/';
$this->load->helper("file"); // load the helper
delete_files($path, true); // delete all files/folders
//rmdir($dirname);
if(rmdir($path)){
echo 'deleted';die;}
else{
echo 'not';die; }
return true;
}
But it always returning not
Deleting directory content:
It will probably work, I have used
$this->load->helper('directory');
$this->load->helper("file");
$dir_fiels = directory_map('resources/captcha/');
$len = sizeOf($dir_fiels);
for($i=0; $i<$len;$i++){
unlink('resources/captcha/'.$dir_fiels[$i]);
}
create an helper. see below:-
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
if ( ! function_exists('remove_directory'))
{
function remove_directory($directory, $empty=FALSE)
{
if(substr($directory,-1) == '/') {
$directory = substr($directory,0,-1);
}
if(!file_exists($directory) || !is_dir($directory)) {
return FALSE;
} elseif(!is_readable($directory)) {
return FALSE;
} else {
$handle = opendir($directory);
while (FALSE !== ($item = readdir($handle)))
{
if($item != '.' && $item != '..') {
$path = $directory.'/'.$item;
if(is_dir($path)) {
remove_directory($path);
}else{
unlink($path);
}
}
}
closedir($handle);
if($empty == FALSE)
{
if(!rmdir($directory))
{
return FALSE;
}
}
return TRUE;
}
}
}
then load this helper in Your controller and call function remove_directory()
/* End of file recursive_helper.php */
/* Location: /application/helpers/recursive_helper.php */
Delete all files:
delete_files('./path/to/your/directory/');
Include sub-folder(s):
delete_files('./path/to/your/directory/', TRUE);
What's the fastest way to delete all files in all sub-folders except those whose filename is 'whatever.jpg' in PHP?
Why not use iterators? This is tested:
function run($baseDir, $notThis)
{
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($baseDir), RecursiveIteratorIterator::LEAVES_ONLY) as $file) {
if ($file->isFile() && $file->getFilename() != $notThis) {
#unlink($file->getPathname());
}
}
}
run('/my/path/base', 'do_not_cancel_this_file.jpg');
This should be what youre looking for, $but is an array holding exceptions.
Not sure if its the fastest, but its the most common way for directory iteration.
function rm_rf_but ($what, $but)
{
if (!is_dir($what) && !in_array($what,$but))
#unlink($what);
else
{
if ($dh = opendir($what))
{
while(($item = readdir($dh)) !== false)
{
if (in_array($item, array_merge(array('.', '..'),$but)))
continue;
rm_rf_but($what.'/'.$item, $but);
}
}
#rmdir($what); // remove this if you dont want to delete the directory
}
}
Example use:
rm_rf_but('.', array('notme.jpg','imstayin.png'));
Untested:
function run($baseDir) {
$files = scandir("{$baseDir}/");
foreach($files as $file) {
$path = "{$badeDir}/{$file}";
if($file != '.' && $file != '..') {
if(is_dir($path)) {
run($path);
} elseif(is_file($path)) {
if(/* here goes you filtermagic */) {
unlink($path);
}
}
}
}
}
run('.');
I used the following code to display the contents of a Folder say images (Both Directories as well as Files in that folder)
<?php
$dir="images/"; // Directory where files are stored
if ($dir_list = opendir($dir))
{
while(($filename = readdir($dir_list)) !== false)
{
$newvar1="$dir$filename";// For Hyperlink Path
?>
<p><a href="<?php echo $newvar1; ?>"><?php echo $filename;
?></a></p>
<?php
}
closedir($dir_list);
}
?>
But the PHP file shows an output with two additional Links
A link to the folder 'images' and
A Link to the 'Homepage'.
I tried to filter those two links with "filesize" function but getting some error.
How can I resolve this?
Skip current dir and parent dir with a check.
while(...) {
if($filename == ".." || $filename == ".") continue;
...
}
Modify your code to something like this:
while(($filename = readdir($dir_list)) !== false)
{
if($filename != '.' || $filename != '..') // This part to check and ignore
$newvar1="$dir$filename";// For Hyperlink Path
else
continue; //while loop will no further be processed!
//...
}
This is a more in-depth answer and I'm so fed up with such things... This is absolutely an horrible piece of code, even though Php does permit such horrible things.
Something like this is easier to read, easier to maintain, and easier to debug:
<?php
$tab = array();
$dir="images/"; // Directory to parse
if ($dir_list = opendir($dir))
{
while(($filename = readdir($dir_list)) !== false)
{
if($filename != ".." && $filename != ".")
{
$tab[$filename] = $dir.$filename; // Hyperlink Path
}
}
closedir($dir_list);
}
/* Display separated from logic */
foreach ($tab as $filename => $hyperlink)
{
echo '<p>'.$filename.'</p>';
}
?>
More compact but a bit less easy to read:
<?php
$tab = array();
$dir="images/"; // Directory to parse
if ($dir_list = opendir($dir)) {
while(($filename = readdir($dir_list)) !== false) {
if($filename != ".." && $filename != ".") {
$tab[$filename] = $dir.$filename; // Hyperlink Path
}
}
closedir($dir_list);
}
/* Display separated from logic */
foreach ($tab as $filename => $hyperlink) {
echo '<p>'.$filename.'</p>';
}
?>
And some people (including my old teachers) tell that "if there's one line of code, don't use {}" (which I strongly disagree because it may lead to errors later on) but here's the "optimized" version:
<?php
$tab = array();
$dir="images/";
if ($dir_list = opendir($dir)) {
while(($filename = readdir($dir_list)) !== false)
if($filename != ".." && $filename != ".")
$tab[$filename] = $dir.$filename; // Hyperlink Path
closedir($dir_list);
}
foreach ($tab as $filename => $hyperlink)
echo '<p>'.$filename.'</p>';
?>
I am trying to delete a folder using this script :
function Delete($path)
{
if (is_dir($path) === true)
{
$files = array_diff(scandir($path), array('.', '..'));
foreach ($files as $file)
{
Delete(realpath($path) . '/' . $file);
}
return rmdir($path);
}
else if (is_file($path) === true)
{
return unlink($path);
}
return false;
}
Delete('tmp');
It works in my Xampp server, but not on my webserver. I have changed the permissions of the folder and of the file it contains to 0777. So it should be writable(or in this case erasable) but nothing happens. I have even tryied giving the absolute path of the folder as the parameter of the function, but still nothing.Any ideas?
Use this :
function delTree($dir)
{
$files = glob( $dir . '*', GLOB_MARK );
foreach( $files as $file
{
if( is_dir( $file ) )
delTree( $file );
else
#unlink( $file );
}
if( is_dir($dir) ) rmdir( $dir );
};
Does it return false? Or it returns true but doesn't actually remove?
Normally I'd just guess it's a permissions problem.
Try making a folder with mkdir from PHP so PHP is the owner (so to speak) and try to remove that with your function.
If it works, it's a permissions/owner issue.
You can Try this code
<?php
$files = glob('application/*'); foreach($files as $file){ if(is_file($file)) unlink($file); }
?>
Or,
function viewDir($path) {
return is_file($path) ?
#unlink($path) :
array_map(__FUNCTION__, glob($path.'/*')) == #rmdir($path);
}
$dir=$_SERVER["DOCUMENT_ROOT"]."/xxxx/xxxx";
echo $dir;
viewDir($dir);
May be some files are opened using php like fopen and that time it will not delete the folder or directory. I have faced the same issue when I tried to delete a file/folder
Try something like this.
<?php
function delete_directory($target) {
if (is_dir($target))
$dir_handle = opendir($target);
if (!$dir_handle)
return false;
while($file = readdir($dir_handle)) {
if ($file != "." && $file != "..") {
if (!is_dir($dirname."/".$file))
unlink($dirname."/".$file);
else
delete_directory($target.'/'.$file);
}
}
closedir($dir_handle);
rmdir($target);
return true;
}
?>
Hope this helps.
Try this line of code to delete a folder or folder files
I hope this will help you
function deleteAll($str) {
if (is_file($str)) {
return unlink($str);
}
elseif (is_dir($str)) {
$scan = glob(rtrim($str,'/').'/*');
foreach($scan as $index=>$path) {
$this->deleteAll($path);
}
return #rmdir($str);
}
}
