Download Entire Folder With PHP FTP (Simple Examples)

Welcome to a tutorial and example of how to download a folder with PHP FTP. Can’t find a native FTP function to download an entire folder automatically? Well, we will have to do it manually then.

That should cover the basics, but read on for detailed examples!

Just click on “download zip” or do a git clone. I have released it under the MIT license, so feel free to build on top of it or use it in your own project.

 

SORRY FOR THE ADS...

But someone has to pay the bills, and sponsors are paying for it. I insist on not turning Code Boxx into a "paid scripts" business, and I don't "block people with Adblock". Every little bit of support helps.

EXAMPLE 1) DOWNLOAD THE ENTIRE FOLDER

<?php
// (A) SETTINGS - CHANGE TO YOUR OWN!
$ftphost = "ftp.site.com";
$ftpuser = "USER";
$ftppass = "PASSWORD";
$source = "/";
$destination = "D:/download/";
 
// (B) CONNECT TO FTP SERVER
$ftp = ftp_connect($ftphost) or exit("Failed to connect to $ftphost");
 
// (C) LOGIN & DOWNLOAD
if (ftp_login($ftp, $ftpuser, $ftppass)) {
  // (C1) GET FILES & FOLDERS
  $files = ftp_mlsd($ftp, $source);
  print_r($files);
 
  // (C2) DOWNLOAD FILES
  if (count($files)!=0) { foreach ($files as $f) { if ($f["type"]=="file") {
    $saveTo = $destination . $f["name"];
    echo ftp_get($ftp, $saveTo, $f["name"])
      ? "Saved to $saveTo"
      : "Error downloading " . $f["name"] ;
  }}}
} else { echo "Invalid user/password"; }
 
// (D) CLOSE FTP CONNECTION
ftp_close($ftp);

This is pretty much the full version of the introduction snippet. The basic mechanics are the same, but this one comes with settings and some extra checks. Take note though, this will only download files in the base folder of the FTP server.

 

 

EXAMPLE 2) DOWNLOAD EVERYTHING (INCLUDING SUBFOLDERS)

<?php
// (A) SETTINGS - CHANGE TO YOUR OWN!
$ftphost = "ftp.site.com";
$ftpuser = "USER";
$ftppass = "PASSWORD";
$source = "/";
$destination = "D:/download/";
 
// (B) CONNECT & LOGIN TO FTP SERVER
$ftp = ftp_connect($ftphost) or exit("Failed to connect to $ftphost");
if (!ftp_login($ftp, $ftpuser, $ftppass)) {
  ftp_close($ftp);
  exit("Invalid user/password");
}
 
// (C) DOWNLOAD EVERYTHING
function ftpGetAll ($path = "/") {
  // (C1) FTP OBJECT & DESTINATION FOLDER
  global $ftp;
  global $destination;
 
  // (C2) CREATE FOLDER ON LOCAL SERVER
  $saveTo = $path=="/" ? $destination : $destination . $path;
  if (!file_exists($saveTo)) {
    if (mkdir($saveTo)) { echo "$saveTo created\r\n"; }
    else { echo "Error creating $saveTo\r\n"; return false; }
  }
 
  // (C3) GET FILES
  $files = ftp_mlsd($ftp, $path);
  if (count($files)!=0) { foreach ($files as $f) {
    // (C4) FOLDER - RECURSIVE LOOP
    if ($f["type"]=="dir") { ftpGetAll($path . $f["name"] . "/"); }
 
    // (C5) FILE - DOWNLOAD
    else {
      echo ftp_get($ftp, $saveTo . $f["name"], $path . $f["name"], FTP_BINARY)
        ? "Saved to " . $saveTo . $f["name"] . "\r\n"
        : "Error downloading " . $path . $f["name"] . "\r\n" ;
    }
  }}
}
ftpGetAll($source);
 
// (D) CLOSE FTP CONNECTION
ftp_close($ftp);

To also download the sub-folders, we have to modify the previous script a little. Keep calm and look carefully –

• We pretty much just moved the entire file download part into function ftpGetAll().
• If it is a folder, we call ftpGetAll() recursively to dig into the sub-folder.

That’s all. All the rest of the mechanics are the same.
