php directory explorer script help - php

I have created this php script which displays the contents of a designated directory and allows users to download each file. Here is the code:
<?php
if ($handle = opendir('test')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo "<a href='test/$file'>$file\n</a><br/>";
}
}
closedir($handle);
}
?>
This script also displays folders, but when I click a folder, it does display the contents of the folder, but in the default Apache autoindex view.
What I would like the script to do when a folder is clicked, is display the contents, but in the same fashion as the original script does (as this is more editable with css and the like).
Would you know how to achieve this?

Don't create a link to the directory itself, but to a php page which displays the contents.
Change your php code to somthing like:
if(isset($_REQUEST['dir'])) {
$current_dir = $_REQUEST['dir'];
} else {
$current_dir = 'test';
}
if ($handle = opendir($current_dir)) {
while (false !== ($file_or_dir = readdir($handle))) {
if(in_array($file_or_dir, array('.', '..'))) continue;
$path = $current_dir.'/'.$file_or_dir;
if(is_file($path)) {
echo ''.$file_or_dir."\n<br/>";
} else {
echo ''.$file_or_dir."\n<br/>";
}
}
closedir($handle);
}
PS write you html code with double quotes.

You need your HREF to point back to your PHP script, and not the directory. You will then need to update your PHP script to now which directory it needs to read.

How to echo out the contents of every text file that in a directory?

I have created a directory with some files in there:
index.php
one.txt
two.txt
three.txt
four.txt
In the index.php page, I am currently using this code to echo out all of the files within the directory:
<?php
$blacklist = array("index.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo "$entry\n";
}
}
closedir($handle);
}
?>
Now, if anyone views the index.php page, this is what they'll see:
one.txt two.txt three.txt four.txt
As you can see from the PHP code, index.php is blacklisted so it is not echoed out.
However, I would like to go a step further than this and echo out the contents of each text file rather than the filenames. With the new PHP code (that I need help with creating), whenever someone visits the index.php page, this is what they'll now see:
(Please ignore what is in the asterisks, they are not a part of the code, they just indicate what each text file contains)
Hello ** this is what the file **one.txt** contains **
ok ** this is what the file **two.txt** contains **
goodbye ** this is what the file **three.txt** contains **
text ** this is what the file **four.txt** contains **
Overall:
I would like to echo out the contents of every file in the directory (they are all text files) aside from index.php.
You could use file_get_contents to put the file into a string.
<?php
$blacklist = array("index.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo "$entry " . file_get_contents($entry) . "\n";
}
}
closedir($handle);
}
?>
Furthermore, you could use PHP's glob function to filter only the .txt files out, that way you do not have to blacklist files if you're going to be adding more files to that directory that need ignored.
Here is how it would be done using the glob function.
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename " . file_get_contents($filename) . "\n";
}
?>
This would print the contents of the files. You can do some workaround if the path is not the current path and writing some kind of boundary between the files contents.
<?php
$blacklist = array("index.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo file_get_contents($entry) . "\n";
}
}
closedir($handle);
}
?>
I hope this helps you.
Never reinvent the wheel. Use composer.
Require symfony/finder
use Symfony\Component\Finder\Finder;
class Foo
{
public function getTextFileContents($dir)
{
$finder = (new Finder())->files()->name('*.txt');
foreach ($finder->in($dir) as $file) {
$contents = $file->getContents();
// do something while file contents...
}
}
}
I would give a chance to some SPL filesystem iterators to accomplish such this task:
$dir = '/home/mydirectory';
$rdi = new \RecursiveDirectoryIterator($dir, \FilesystemIterator::SKIP_DOTS);
$rdi = new \RegexIterator($rdi, '/\.txt$/i');
$iterator = new \RecursiveIteratorIterator($rdi, \RecursiveIteratorIterator::CHILD_FIRST);
foreach ($iterator as $file) {
echo 'Contents of the '.$file->getPathname().' is: ';
echo file_get_contents($file->getPathname());
}
This will recursively find & iterate all .txt files in given directory, including sub-directories.
Since each $file in iteration is a FilesystemIterator instance, you can use all related methods for additional controls like $file->isLink() (true for symbolic links), $file->isReadable() (false for unreadable files) etc..
If you don't want lookup sub-folders, just change the RecursiveDirectoryIterator in the second line from:
$rdi = new \RecursiveDirectoryIterator($dir, \FilesystemIterator::SKIP_DOTS);
to:
$rdi = new \DirectoryIterator($dir, \FilesystemIterator::SKIP_DOTS);
Hope it helps.
As #brock-b said, you could use glob to get the full list of files and file_get_contents to grab the contents:
$blacklist = array('index.php');
$files = glob('*.txt'); # could be *.* if needed
foreach ($files as $file) {
if (!in_array(basename($file), $blacklist)) {
echo file_get_contents($file);
}
}
Note: the blacklist wont be hit since you're seeking for *.txt files. Only useful when doing an *.* or *.php file search

Listing Directories: Opendir()

I'm working on a small script and I want to list the contents of a directory, make them into hyperlinks, and then edit those hyperlinks to look pretty (I.e. not show an ugly super long path name), then limit the number files echoed back to the browser. Also, I need the most recent files echoed back only.
I was thinking about using this:
<?php
$path = "/full/path/to/files";
if ($handle = opendir($path)) {
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
$files .= ''.$file.'';
}
}
closedir($handle);
}
?>
or this:
<?php
$sub = ($_GET['dir']);
$path = 'enter/your/directory/here/';
$path = $path . "$sub";
$dh = opendir($path);
$i=1;
while (($file = readdir($dh)) !== false) {
if($file != "." && $file != "..") {
if (substr($file, -4, -3) =="."){
echo "$i. $file <br />";
}else{
echo "$i. <a href='?dir=$sub/$file'>$file</a><br />";
}
$i++;
}
}
closedir($dh);
?>
But I dont want to list the files like this:
C:/example/example2/Hello.pdf
I want to edit the variable. Is that possible? To make it say something as simple as "Hello."
I want to limit the amount of files listed as well. For example: only list the first 5 files, or last 5, etc. Is there a function or some kind of parameter for that?
I appreciate any help or push in the right direction. Thanks
I'm on my phone so providing a code example will be tough. Why not iterate through the directories, storing the file name in an array, with the absolute path as the value for that key?
EDIT: You can use basename to aid you in doing this.

Instruct PHP To Ignore Scanning A Folder

I've been working with a handy php script, which scans my site and spits out links to all the pages it finds. The problem is, it's also scanning my 'includes' folder, which contains all my .inc.php files.
Obviously I'd rather it ignore this folder when scanning the site, but for the life of me I can't see how to edit the script to tell it to do so.
The script is:
<?php
// starting directory. Dot means current directory
$basedir = ".";
// function to count depth of directory
function getdepth($fn){
return (($p = strpos($fn, "/")) === false) ? 0 : (1 + getdepth(substr($fn, $p+1)));
}
// function to print a line of html for the indented hyperlink
function printlink($fn){
$indent = getdepth($fn); // get indent value
echo "<li class=\"$indent\"><a href=\"$fn\">"; //print url
$handle = fopen($fn, "r"); //open web page file
$filestr = fread($handle, 1024); //read top part of html
fclose($handle); //clos web page file
if (preg_match("/<title>.+<\/title>/i",$filestr,$title)) { //get page title
echo substr($title[0], 7, strpos($title[0], '/')-8); //print title
} else {
echo "No title";
}
echo "</a></li><br>\n"; //finish html
}
// main function that scans the directory tree for web pages
function listdir($basedir){
if ($handle = #opendir($basedir)) {
while (false !== ($fn = readdir($handle))){
if ($fn != '.' && $fn != '..'){ // ignore these
$dir = $basedir."/".$fn;
if (is_dir($dir)){
listdir($dir); // recursive call to this function
} else { //only consider .html etc. files
if (preg_match("/[^.\/].+\.(htm|html|php)$/",$dir,$fname)) {
printlink($fname[0]); //generate the html code
}
}
}
}
closedir($handle);
}
}
// function call
listdir($basedir); //this line starts the ball rolling
?>
Now I can see where the script is told to ignore certain files, and I've tried appending:
&& $dir != 'includes'
...to it in numerous places, but my php knowledge is simply too shaky to know exactly how to integrate that code into the script.
If anyone can help, then you'd be saving me an awfully large headache. Cheers.
Add it this line:
if ($fn != '.' && $fn != '..'){ // ignore these
so it's
if ($fn != '.' && $fn != '..' && $fn != 'includes'){ // ignore these
Your path needs to be absolute. Add it at the top of listdir
function listdir($basedir){
if($basedir == '/path/to/includes') {
return;
} [...]
This also makes sure that only one includes folder will be ignored.

Dynamic link created based on new file upload?

Every 72 hours I upload a new PHP file to my server. (well actually it is an xml file transformed on the server with php) Is there a method to create a link on an html page that links to the "new" PHP doc automatically everytime a new file is uploaded?
I don't want to manually change the link every 72 hours. I would ultimately like to have an html page with a list of links to every new doc that is uploaded. I found this for images but I need someting like this but for PHP files and links.
http://net.tutsplus.com/articles/news/scanning-folders-with-php/
Any help would be very appreciated.
I found a solution that add links to the xml files. Now I just need to figure out how to add a link to reference the xslt sheet for each new xml file that is upload AUTOMATICALLY. I am not sure how to do this but any help would be very helpful. Thanks for everyones help.
<?php
$count = 0;
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {$count++;
print("".$file."<br />\n");
}
}
echo '<br /><br />Return';
closedir($handle);
}
?>
To read in a directory of files and then sort them by upload time you can just use:
$files = glob("files/*.xml");
$files = array_combine($files, array_map("filemtime", $files));
arsort($files);
print "link: " . current($files); // make that an actual <a href=
You can do that pretty easily with PHP function readdir:
http://php.net/manual/en/function.readdir.php
Simply loop through the files in the directory where you upload files and have php output a link for each.
ie:
<?php
if ($handle = opendir('/path/to/upload_dir')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
echo '' . $file . '<br />';
}
}
closedir($handle);
}
?>
You'll need to edit the http:// URL on the href to point to the correct download URL for your server, as well as the server path for opendir.
Hope that helps.
list by filetype
<?php
if ($handle = opendir('/path/to/dir')) {
while (false !== ($file = readdir($handle))) {
if (strpos($file, '.php',1)||strpos($file, '.xml',1) ) {
echo "<p>$file</p>";
}
}
closedir($handle);
}

Find all .htaccess files and replace content with PHP script

I need to create a script that will find all my .htaccess files on my server and replace their content with the new content I need in order for my pages to be SEO friendly.
So far I've come across a few scripts that will find all the .htaccess files but I need to be able to open, replace all content with new and save with the proper permissions.
Can anyone help me with the following code to add the extra functionality I need?
<?php
function searchDir($dir) {
$dhandle = opendir($dir);
if ($dhandle) {
// loop through it
while (false !== ($fname = readdir($dhandle))) {
// if the element is a directory, and does not start with a '.' or '..'
// we call searchDir function recursively passing this element as a parameter
if (is_dir( "{$dir}/{$fname}" )) {
if (($fname != '.') && ($fname != '..')) {
echo "Searching Files in the Directory: {$dir}/{$fname} <br />";
searchDir("$dir/$fname");
}
// if the element is an .htaccess file then replace content
} else {
if($fname == ".htaccess")
{
echo "Replacing content of file ".$dir/$fname."<br />";
// I need the code for editing the files here.
}
}
}
closedir($dhandle);
}
}
searchDir(".");
?>
Modify your else loop with this
else {
if($fname == ".htaccess")
{
echo "Replacing content of file ".$dir/$fname."<br />";
// I need the code for editing the files here.
$htaccess_content = " Your htaccess string " ; // you can do this assignment at the top
file_put_contents("{$dir}/{$fname}",$htaccess_content) ;
}
}
Use file_get_contents() and file_put_contents().
