Before sorting the listed files/directories alphabetically, I coverted the function into the way listing the files/directories in list(ul/li) manner instead of the current 'intent' one. I reckon the list way is the most proper way to list nested items. Here is the new function:
PHP Code:
function getDirectory( $path = '.'){
$ignore = array( 'cgi-bin', '.', '..' );
// Directories to ignore when listing output. Many hosts
// will deny PHP access to the cgi-bin.
$dh = @opendir( $path );
// Open the directory to the handle $dh
while( false !== ( $file = readdir( $dh ) ) ){
// Loop through the directory
if( !in_array( $file, $ignore ) ){
// Check that this file is not to be ignored
// Just to add spacing to the list, to better
// show the directory tree.
if( is_dir( "$path/$file" ) ){
// Its a directory, so we need to keep reading down...
//Add a class as selector for the jQuery sorting later.
echo "<li>$file<ul class='has-children'>";
getDirectory( "$path/$file");
// Re-call this same function but on a new directory.
// this is what makes function recursive.
echo "</li>";
} else {
echo "<li>$file</li>";
// Just print out the filename
}
}
}
echo "</ul>";
closedir( $dh );
// Close the directory handle
}
//Add a class as selector for the jQuery sorting later.
echo "<ul class='has-children'>";
getDirectory( "." );
Then add the following jQuery codes to sort the lists:
Code:
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(function() {
$('ul.has-children').each(function() {
var $t=$(this);
var Li=$t.find('>li').get();
Li.sort(function(a, b) {
var A = $(a).text().toUpperCase();
var B = $(b).text().toUpperCase();
if (A < B) return -1; // changing to 1 to sort in DESC order...
if (A > B) return 1; // changing to -1 to sort in DESC order...
return 0;
});
$.each(Li,function(i,v) {
$t.append(v);
});
});
</script>
Hi! I was looking for a code snippet for directory traversal and i found tours (i feel too lazy tonight to do it by myself)
I tested on linux and works ok, on windows ok except for long paths.
And I actually need to index some dirs and files that have a really deep dir structure.
It just freezes when the path is longer than 255...
Do you have any ideas on how i can traverse such a structure?
Thank you very much!
Any help is really appreciated!
To be honest, I don't really like the supressing of potentional errors( @opendir ).
I was actually creating an online file management system, and already had this coded. (Currently secured it by IP Access).
PHP Code:
<?php
if($_SERVER['REMOTE_ADDR'] != 'YOUR_IP') {
die("Only the webmaster can access this page's content. Please go back and open another file.");
# system call do recursive dir listing. assign listing to array and sort on each
# pass with foreach loop.
# once you have array you can go further as sorting & recursion done.
$rtv = `ls -RAFr /home/web.symfony/`; // system call to start listing
$dir = array();
foreach( preg_split("/\n/", $rtv) as $line ) {
if(preg_match("/:$/", $line)) { // if directory
if($line && $current_path) { // after first pass
asort($dir[$current_path]); // cool & easy sort
}
$current_path = preg_replace("/:$/", '', $line); // discard : from the path
}else if ($line != '') {
$dir[$current_path][] = $line; // listing of the previous pass
}
}
Before sorting the listed files/directories alphabetically, I coverted the function into the way listing the files/directories in list(ul/li) manner instead of the current 'intent' one. I reckon the list way is the most proper way to list nested items. Here is the new function:

$dh = @opendir( $path );
// Open the directory to the handle $dh
while( false !== ( $file = readdir( $dh ) ) ){
// Loop through the directory
if( !in_array( $file, $ignore ) ){
// Check that this file is not to be ignored
// Just to add spacing to the list, to better
// show the directory tree.
if( is_dir( "$path/$file" ) ){

//Add a class as selector for the jQuery sorting later.
echo "<li>$file<ul class='has-children'>";
getDirectory( "$path/$file");
// Re-call this same function but on a new directory.
// this is what makes function recursive.
echo "</li>";
} else {
echo "<li>$file</li>";
// Just print out the filename
}
}
}
echo "</ul>";
closedir( $dh );
// Close the directory handle
}
//Add a class as selector for the jQuery sorting later.
echo "<ul class='has-children'>";
getDirectory( "." );
Then add the following jQuery codes to sort the lists:
Code:
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(function() {
$('ul.has-children').each(function() {
var $t=$(this);
var Li=$t.find('>li').get();
Li.sort(function(a, b) {
var A = $(a).text().toUpperCase();
var B = $(b).text().toUpperCase();
if (A < B) return -1; // changing to 1 to sort in DESC order...
if (A > B) return 1; // changing to -1 to sort in DESC order...
return 0;
});
$.each(Li,function(i,v) {
$t.append(v);
});
});
</script>
Have fun
Here is the PHP way to do the same sorting as the above with jQuery:
PHP Code:
<?
$tree=array();
function getDirectory( $path = '.'){
$ignore = array( 'cgi-bin', '.', '..' );
// Directories to ignore when listing output. Many hosts
// will deny PHP access to the cgi-bin.
$dh = @opendir( $path );
// Open the directory to the handle $dh
//Make counter
$j=0;
$temp=array();
while( false !== ( $file = readdir( $dh ) ) ){
// Loop through the directory
if( !in_array( $file, $ignore ) ){
// Check that this file is not to be ignored
// Feed with file name
$temp[$j]['name']=$file;
if( is_dir( "$path/$file" ) ){
// Its a directory, so we need to keep reading down...
$temp[$j]['children']=getDirectory( "$path/$file");
}
}
$j++; //counting
}
return $temp;
closedir( $dh );
// Close the directory handle
}//end of function
//Put the file directory system in an array first...
$tree=getDirectory("/your-dirtory/here");
$type='desc'; //set sorting type 'desc' or 'asc'
//recursive function for sorting arrays
function getSort(&$temp) {
global $type;
switch ($type) {
case 'desc':
rsort($temp);
break;
case 'asc':
sort($temp);
break;
}
foreach($temp as &$t) {
if(is_array($t['children']))
getSort($t['children']);
}
} //end of function
//Go through arrays again for sorting...now we have new sorted array $tree...
getSort($tree);
?>
<pre>
<?
print_r($tree); // output
?>
</pre>
hello,
well for me this function make the error : Warning: readdir() expects parameter 1 to be resource, boolean given
for
while (false !== ($file = readdir($dh))) {
any idea?
I must say I don't think it's a good practice to put html in your code, it's better to separate front presentation from back, so this function will be more logic to integrate to make others operations (of course it's not a big deal to modify)
ok it was a problem with directory which doesn't exist, the strnage is function doesn't stop and go to infinite recursive
another list function I found useful : http://www.webmaster-talk.com/php-fo...rectories.html
I just want to say thank you for the information.
It is very valuable for me..newbie here and encountering the same situation.
Thanks and keep up the good work..
The functions on this site did not work for me.
I wrote one myself.
It converts the directory structure into an array.
It returns some relevant data in the {data} key and loops through the rest.
It might not be the cleanest script but it does the job for me.
Maybe it helps someone.
PHP Code:
//$include overrides $exclude. $include should be an array of file extensions eg. array("jpg", "png", "gif")
function readDirectory($path="./", $exclude=array(".", "..", ".htaccess"), $include=false){
$ds = "/";
if(!$path){ $path=$this->path;}
$return = array();
$return['{data}']['path'] = $path;
$return['{data}']['has_files'] = 0;
$return['{data}']['has_dirs'] = 0;
if(is_dir($path)){
$dir = opendir($path);
while ($file = readdir($dir)) {
thank for your code. but i want to call getDirectory() function with parameter like below example:
getDirectory("http://updatesofts.com");
does it work?
if not how to i can?
thanks.
