Question

I have a function getting the recursive folder’s filename inside a specific path:

function getDirectory( $path = '.', $level = 0 ){

$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
$files_matched = array(); 


while( false !== ( $file = readdir( $dh ) ) ){
// Loop through the directory

    if( !in_array($file, $ignore ) && !preg_match("/^.*\.(rar|txt)$/", $file) ){
    // Check that this file is not to be ignored

        if( is_dir( "$path/$file" ) ){
        // Its a directory, so we need to keep reading down...

            echo "<strong>$spaces $file</strong><br />";

            getDirectory( "$path/$file", ($level+1) );
            // Re-call this same function but on a new directory.
            // this is what makes function recursive.

        } else {
            $files_matched[$i] = $file;
            $i++;
        }

    }

}

closedir( $dh );
// Close the directory handle
return $files_matched;
}

echo "<pre>";
$files = getDirectory("F:\Test");
foreach($files as $file) printf("%s<br />", $file);
echo "</pre>";

I used $files_matched to stored the filename in an array.

And for the above result, it only display the filename under “F:\test”.

Actually, I have a sub-folder under “F:\test”. How can I display those filename using the array for storage?

If I modified the code:

$files_matched[$i] = $file;
$i++;

into:

echo "$files<br />";

This will be worked fine and I just don’t know why use array to store the filename for later process is not work??

Thanks for help.

I don’t remember where I got this code from, but it works.

<?php

function getDirectoryTree( $outerDir , $x){
    $dirs = array_diff( scandir( $outerDir ), Array( ".", ".." ) );
    $dir_array = Array();
    foreach( $dirs as $d ){
        if( is_dir($outerDir."/".$d)  ){
            $dir_array[ $d ] = getDirectoryTree( $outerDir."/".$d , $x);
        }else{
            if (($x)?ereg($x.'$',$d):1)
            $dir_array[ $d ] = $d;
        }
    }
    return $dir_array;
}

var_dump( getDirectoryTree(getcwd(),'') );
