and this is my functiosn code :

function ftpRecursiveFileListing($ftpConnection, $path) {
static $allFiles = array();
$contents = ftp_nlist($ftpConnection, $path);

foreach($contents as $currentFile) {
    // assuming its a folder if there's no dot in the name
    if (strpos($currentFile, '.') === false) {
        $this->ftpRecursiveFileListing($ftpConnection, $currentFile);
    }
    $allFiles[$path][] = $currentFile;
            //break;
}
return $allFiles;
}

public function test(){
    $ftp_server = "ftp.mywebsite.com";
    $ftp_user_name = "user@mywebsite.com";
    $ftp_user_pass = "mypswd";
    // Mise en place d'une connexion basique
    $conn_id = ftp_connect($ftp_server);
    // Identification avec un nom d'utilisateur et un mot de passe
    $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
    echo "<pre>";
    $handler = $this->ftpRecursiveFileListing($conn_id, '/');
    print_r($handler);

}

many thanks

You can use local array in order the build the tree.

function ftpRecursiveFileListing($ftpConnection, $path, $parentId) {
    static $cnt = 0;
    $files = array();
    $contents = ftp_nlist($ftpConnection, $path);

    foreach($contents as $currentFile) {
        $currentFileArray = array();
        $currentFileArray[text] = $currentFile;
        $currentFileArray[parentId] = $parentId;
        $currentFileArray[id] = $cnt++;
        // assuming its a folder if there's no dot in the name
        if (strpos($currentFile, '.') === false)
            $currentFileArray[children] = $this->ftpRecursiveFileListing($ftpConnection, $currentFile, $currentFileArray[id]);
        $files [] = $currentFileArray;
    }
return $files ;
}

Call the function for the first time will be with:

$handler = $this->ftpRecursiveFileListing($conn_id, '/', null);

This only basic data - you can add more keys to the arrays
