PHP - 从FTP中的所有目录中获取所有文件

Question

i have this doubt, i can download all files from an specific directory, but how can i download all files from all directories in an specific folder? My code to download from a directory is like this:

$ftp_server = "server";
$ftp_user = "user";
$ftp_pass = "pass";

$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server"); 

function get_file($strDir) {
    global $conn_id;
    $contents = ftp_nlist($conn_id, $strDir);   
    for($i=0; $i<count($contents); $i++) {
        if (strstr($contents[$i], "OUT") !== FALSE) {
            if (ftp_get($conn_id, substr($contents[$i],1), $contents[$i], FTP_ASCII)) {
                echo "Successfully written to ".substr($contents[$i],1)."<br>";
            } else {
                echo "There was a problem ".substr($contents[$i],1)."<br>";
            }

        }
        else {
            mkdir(substr($contents[$i],1),0777,true);                   
            $a = get_file($contents[$i]);
        }
    }
    return 1;
}

if (ftp_login($conn_id, $ftp_user, $ftp_pass)) {
    $contents = ftp_nlist($conn_id, "OUT");
    for($i=0; $i<count($contents); $i++) {
            echo "Directory = " . $contents[$i] . "<br>";   
            ftp_get($conn_id, $contents[$i], $contents[$i], FTP_BINARY);
    }
}

so, how can i download ALL the files from ALL directories?

You can use RecursiveDirectoryIterator to get all files in sub directories of a specific directory
