I've been making a function to scan files in a directory and scan for a specific file in the one of the folders in the scanned directory. To put it in simple terms,
Scanned Director -> Scan Folder in Director for specific file
Here's the code I've been using.
function __construct(){
$name = array_diff(scandir($_SERVER['CONTEXT_DOCUMENT_ROOT']."/apps/"), array('..', '.'));
foreach($name as $key)
{
$this->installed = array($key);
while($this->check($key)){}
}
}
function check($name){
if(file_exists($_SERVER['CONTEXT_DOCUMENT_ROOT']."/apps/".$name."/index.php"))
{
echo "YES";
}
else
{
echo "NO";
}
}
but the output returns "NO" even if the file is already in the folder. Is there a solution to this?
Please check the below points again and proceed.
Please check the file path
Your folder and file must have permission to read.
file_exists($filename) function will return FALSE for symlinks pointing to non-existing files.
Your $name variable returns an array you have used that in the file_exists($filename)
I have made some modification in the code and i have checked its working fine here.
$name = array_diff(scandir($_SERVER['CONTEXT_DOCUMENT_ROOT']."/apps/"), array('..', '.'));
foreach($name as $key) {
$this->installed = array($key);
while($this->check($key)){}
if(file_exists($_SERVER['CONTEXT_DOCUMENT_ROOT']."/apps/".$key."/index.php")){
echo "YES";
}else{
echo "NO";
}
}

I'm trying to list all PHP files in a specified directory and for it to recursively check all sub-directories until it finds no more, there could be numerous levels.
The function I have below works fine with the exception that it only recurses down one level.
I've spent hours trying to see where I'm going wrong, I'm calling the scanFiles() when it finds a new directory but this only seems to work one level down and stop, any help greatly appreciated.
Updated:
function scanFiles($pParentDirectory)
{
$vFileArray = scandir($pParentDirectory);
$vDirectories = array();
foreach ($vFileArray as $vKey => $vValue)
{
if (!in_array($vValue, array('.', '..')) && (strpos($vValue, '.php') || is_dir($vValue)))
{
if (!is_dir($vValue))
$vDirectories[] = $vValue;
else
{
$vDirectory = $vValue;
$vSubFiles = scanFiles($vDirectory);
foreach ($vSubFiles as $vKey => $vValue)
$vDirectories[] = $vDirectory.DIRECTORY_SEPARATOR.$vValue;
}
}
}
return $vDirectories;
}
You can do this easily like this:
// helper function
function getFiles(&$files, $dir) {
$items = glob($dir . "/*");
foreach ($items as $item) {
if (is_dir($item)) {
getFiles($files, $item);
} else {
if (end(explode('.', $item)) == 'php') {
$files[] = basename($item);
}
}
}
}
// usage
$files = array();
getFiles($files, "myDir");
// debug
var_dump($files);
myDir looks like this: has php files in all dirs
Output:
P.S. if you want the function to return the full path to the found .php files, remove the basename() from this line:
$files[] = basename($item);
This will then produce result like this:
hope this helps.
This is because $vDirectory is just a folder name, so scanDir looks in the current folder for it, not the sub folder.
What you want to do is to pass in the path to the folder, not just the name. This should be as simple as changing your recursive call to scanFiles($pParentDirectory . DIRECTORY_SEPARATOR . $vDirectory)
Your main problem is functions like scanDir or isDir need the full file path to work.
If you pass the full file path to them, it should work correctly.
I have a zip file containing one folder, that contains more folders and files, like this:
myfile.zip
-firstlevel
--folder1
--folder2
--folder3
--file1
--file2
Now, I want to extract this file using PHPs ZipArchive, but without the "firstlevel" folder. At the moment, the results look like this:
destination/firstlevel/folder1
destination/firstlevel/folder2
...
The result I'd like to have would look like this:
destination/folder1
destination/folder2
...
I've tried extractTo, which produces the first mentioned result, and copy(), as suggested here, but this doesn't seem to work at all.
My current code is here:
if($zip->open('myfile.zip') === true) {
$firstlevel = $zip->getNameIndex(0);
for($i = 0; $i < $zip->numFiles; $i++) {
$entry = $zip->getNameIndex($i);
$pos = strpos($entry, $firstlevel);
if ($pos !== false) {
$file = substr($entry, strlen($firstlevel));
if(strlen($file) > 0){
$files[] = $file;
}
}
}
//attempt 1 (extractTo):
//$zip->extractTo('./test', $files);
//attempt 2 (copy):
foreach($files as $filename){
copy('zip://'.$firstlevel.'/'.$filename, 'test/'.$filename);
}
}
How can I achieve the result I'm aiming for?
Take a look at my Quick Unzipper script. I wrote this for personal use a while back when uploading large zip files to a server. It was a backup, and 1,000s of files take forever with FTP so using a zip file was faster. I use Git and everything, but there wasn't another option for me. I place this php file in the directory I want the files to go, and put the zip file in the same directory. For my script, they all have to operate in the same directory. It was an easy way to secure it for my needs, as everything I needed was in the same dir.
Quick Unzipper: https://github.com/incomepitbull/QuickUnzipper/blob/master/unzip.php
I linked the file because I am not showcasing the repo, just the code that makes the unzip tick. With modern versions of PHP, there should't be anything that isn't included on your setup. So you shouldn't need to do any server config changes to use this.
Here is the PHP Doc for the ZipArchive class it uses: http://php.net/manual/en/class.ziparchive.php
There isn't any included way to do what you want, which is a shame. So I would unzip the file to a temp directory, then use another function to copy the contents to where you want. So when using ZipArchive, you will need to return the first item to get the folder name if it is unknown. If the folder is known, ie: the same pesky folder name every time, then you could hard code the name.
I have made it return the first item from the index. So if you ALWAYS have a zip with 1 folder inside it, and everything in that folder, this would work. However, if you have a zip file without everything consolidated inside 1 folder, it would fail. The code I have added will take care of your question. You will need to add further logic to handle alternate cases.
Also, You will still be left with the old directory from when we extract it to the temp directory for "processing". So I included code to delete it too.
NOTE: The code uses a lot of if's to show the processing steps, and print a message for testing purposes. You would need to modify it to your needs.
<?php
public function copyDirectoryContents($source, $destination, $create=false)
{
if ( ! is_dir($source) ) {
return false;
}
if ( ! is_dir($destination) && $create === true ) {
#mkdir($destination);
}
if ( is_dir($destination) ) {
$files = array_diff(scandir($source), array('.','..'));
foreach ($files as $file)
{
if ( is_dir($file) ) {
copyDirectoryContents("$source/$file", "$destination/$file");
} else {
#copy("$source/$file", "$destination/$file");
}
}
return true;
}
return false;
}

{
if(!isset($options['traverseSymlinks']))
$options['traverseSymlinks']=false;
$files = array_diff(scandir($directory), array('.','..'));

$firstDir = null; // holds the name of the first directory
$zip = new ZipArchive;

if ($res === TRUE) {
$firstDir = $zip->getNameIndex(0);

$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);
}
}
?>
Please note that I want the compartment number to change.
<?php
$compartment = "1";
/* HERE I NEED SOME SCRIPT TO FIND THE EXTENSION OF THE FILE NAME $compartment AND TO SAVE THAT AS A VARIABLE NAMED 'EXTENSION'.*/
if (file_exists($compartment.$extension)) {
echo "$compartment.$extension exists!
} else {
echo "No file name exists that is called $compartment. Regardless of extension."
}
?>
<?php
$compartment = "2";
/* HERE I NEED SOME SCRIPT TO FIND THE EXTENSION OF THE FILE NAME $compartment AND TO SAVE THAT AS A VARIABLE NAMED 'EXTENSION'.*/
if (file_exists($$compartment.$extension)) {
echo "$compartment.$extension exists!
} else {
echo "No file name exists that is called $compartment. Regardless of extension."
}
?>
Thank You!
You need glob().
$compartment = "2";
$files = glob("/path/to/files/$compartment.*"); // Will find 2.txt, 2.php, 2.gif
// Process through each file in the list
// and output its extension
if (count($files) > 0)
foreach ($files as $file)
{
$info = pathinfo($file);
echo "File found: extension ".$info["extension"]."<br>";
}
else
echo "No file name exists called $compartment. Regardless of extension."
by the way, what you are doing above is crying for a loop. Don' repeat your code blocks, but wrap one of them into this:
$compartments = array(1, 3, 6, 9); // or whichever compartments
// you wish to run through
foreach ($compartments as $compartment)
{
..... insert code here .......
}
Look up:
glob — Find pathnames matching a pattern
fnmatch — Match filename against a pattern
pathinfo — Returns information about a file path
I tried to write a script to list all files in directories and subdirectories and so on.. The script works fine if I don't include the check to see whether any of the files are directories. The code doesn't generate errors but it generates a hundred lines of text saying "Directory Listing of ." instead of what I was expecting. Any idea why this isn't working?
<?php
//define the path as relative
$path = "./";
function listagain($pth)
{
//using the opendir function
$dir_handle = #opendir($pth) or die("Unable to open $pth");
echo "Directory Listing of $pth<br/>";
//running the while loop
while ($file = readdir($dir_handle))
{
//check whether file is directory
if(is_dir($file))
{
//if it is, generate it's list of files
listagain($file);
}
else
{
if($file!="." && $file!="..")
echo "<a href='$file'>$file</a><br/>";
}
}
//closing the directory
closedir($dir_handle);
}
listagain($path)
?>
The first enties . and .. refer to the current and parent directory respectivly. So you get a infinite recursion.
You should first check for that before checking the file type:
if ($file!="." && $file!="..") {
if (is_dir($file)) {
listagain($file);
} else {
echo ''.htmlspecialchars($file).'<br/>';
}
}
The problem is, variable $file contains only basename of path. So, you need to use $pth.$file.
