recursive glob ?

Peuplarchie · 01-31-2010, 03:23 AM

Good day to you all,
is there a way that I can use glob recursive ly in the following code ?

PHP Code:


			

<?PHP
foreach(glob('Photos/*', GLOB_ONLYDIR) as $dir) {
  echo '<b>'.$dir.'</b><br>';
}  
?>

Thanks!

If you look down in the comments on the docs page, you will find many solutions. One such being this:

PHP Code:


			
$dir_iterator = new RecursiveDirectoryIterator("/path");
$iterator = new RecursiveIteratorIterator($dir_iterator, RecursiveIteratorIterator::SELF_FIRST);
// could use CHILD_FIRST if you so wish

foreach ($iterator as $file) {
    echo $file, "\n";
}

Of coarse, that would return both files and folders. Some other options are also available such as running glob in a loop of some sort.

OK, here's a sweet little function I made that does exactly what you need:

PHP Code:


			
function glob_recursive($dir)
{
    static $g = array();
    
    foreach(glob($dir,GLOB_ONLYDIR) as $i=>$k)
    {
        $g[] = $k;
        glob_recursive($k.'/*');
    }
    
    return $g;
}

And use like so:

PHP Code:


			
print_r(glob_recursive('dingo/*'));

The only problem is, you can't use it twice. I'll let you figure out how to fix that though.

Yes ok,
How can I but one on each line ?

Can I also not the parentasis and the "array" word and his number ?

How can I display the folder that has folder in it as bold.
And the folders that as files in it, as links ?

It sounds like you don't know much about arrays.. You may want to read this:

http://us.php.net/manual/en/language.types.array.php

The function I gave you returns an array which you can loop through and format as you wish. The rest is up to you man.

Your code skips all files and will return an empty array if there's no any subfolders.

Your code skips all files and will always return an empty array if there's no subfolders initially. A revised codes could be:

PHP Code:


			
function glob_recursive($dir)

{

    static $g = array();

    

    foreach(glob($dir) as $i=>$k)

    {

        if (is_dir($k))

            glob_recursive($k.'/*');

        else

            $g[] = $k;

    }

    return $g;

}



// Show human-readable dump of array contents

echo nl2br(print_r(glob_recursive('dingo/*'),true));
