Directory Reading

NightmareXX

At the moment i have the following code for reading a directory:

<?php
$directorycodepnsdef = opendir('./modelleruploads');
while ($filescodepnsdef = readdir($directorycodepnsdef))
{
$file_arraycodepnsdef[] = $filescodepnsdef;
}
foreach ($file_arraycodepnsdef as $filescodepnsdef)
{
//echo "<tr><td>";
if($filescodepnsdef == ".." || $filescodepnsdef == ".")
{
continue;
} ?>

This script reads everything in the directory and the folder names. All i want it to do is just read the folders, not the files inside the folders.

Please help 🙂

Check out is_dir()

Well that's helped me to the extent that i can now tell if a directory exists. But how do i get it to display the directory name?

That should be fairly obvious. What have you tried?

NightmareXX

Errrrr...

<?
$dir = is_dir('.');
print $dir;
?>

I'm not particularlly good at PHP yet. I only started learning a few weeks ago 🙁

An 'answer' would be good. With an explaination would be even better 😃

Here's an example to get you started...

if ($handle = opendir($path)) { // create a file handle and open a directory
	while (false !== ($fileordir = readdir($handle))) { 
// $fileordir now contains a single name of a file or directory in $path
// loop until we've read them all
		if (is_dir("$path/$fileordir")) echo $fileordir;  

// BINGO (watch out for '.' and '..')
	}
	closedir($handle); // clean up
}

Yay 😃 It works well.

I added my own bit of code, taken from the first post that stopped it showing the '.' and '..'.

if ($handle = opendir($path)) { // create a file handle and open a directory 
    while (false !== ($fileordir = readdir($handle))) {  

// $fileordir now contains a single name of a file or directory in $path 
// loop until we've read them all 
        if (is_dir("$path/$fileordir")) 
if($fileordir== ".." || $fileordir== ".") 
{ continue; }
echo $fileordir;   

// BINGO (watch out for '.' and '..') 
    } 
    closedir($handle); // clean up 
}

I added my own little bit of code at the beggining of the page so that you can 'browse' the directory.
You click the folder and it adds a ?dir=directory at the end. I'll update the code on this page when i get a chance to see the code again.
