Upload Entire Directory via PHP FTP

Question

I'm trying to write a script that will upload the entire contents of a directory stored on my server to other servers via ftp.

I've been reading through the documentation on www.php.net, but can't seem to find a way to upload more then one file at a time.

Is there a way to do this, or is there a script that will index that directory and create an array of files to upload?

Thanks in advance for your help!

Answer 1

Once you have a connection open, uploading the contents of a directory serially is simple:

foreach (glob("/directory/to/upload/*.*") as $filename)
    ftp_put($ftp_stream, basename($filename) , $filename, FTP_BINARY);

Uploading all files in parallel would be more difficult.

Answer 2

So, I took @iYETER's code, and wrapped it as a class object.

You can call this code by these lines:

$ftp = new FtpNew("hostname");

$ftpSession = $ftp->login("username", "password");

if (!$ftpSession) die("Failed to connect.");

$errorList = $ftp->send_recursive_directory("/local/dir/", "/remote/dir/");
print_r($errorList);

$ftp->disconnect();

It recursively crawls local dir, and places it on remote dir relative. If it hits any errors, it creates a array hierarchy of every file and their exception code (I only capture 2 so far, if it's another error, it throws it default route for now)

The class this is wrapped into:

<?php
//Thanks for iYETER on http://stackoverflow.com/questions/927341/upload-entire-directory-via-php-ftp

class FtpNew {
private $connectionID;
private $ftpSession = false;
private $blackList = array('.', '..', 'Thumbs.db');
public function __construct($ftpHost = "") {
    if ($ftpHost != "") $this->connectionID = ftp_connect($ftpHost);
}

public function __destruct() {
    $this->disconnect();
}

public function connect($ftpHost) {     
    $this->disconnect();
    $this->connectionID = ftp_connect($ftpHost);
    return $this->connectionID;
}

public function login($ftpUser, $ftpPass) {
    if (!$this->connectionID) throw new Exception("Connection not established.", -1);
    $this->ftpSession = ftp_login($this->connectionID, $ftpUser, $ftpPass);
    return $this->ftpSession;
}

public function disconnect() {
    if (isset($this->connectionID)) {
        ftp_close($this->connectionID);
        unset($this->connectionID);
    }
}

public function send_recursive_directory($localPath, $remotePath) {
    return $this->recurse_directory($localPath, $localPath, $remotePath);
}

private function recurse_directory($rootPath, $localPath, $remotePath) {
    $errorList = array();
    if (!is_dir($localPath)) throw new Exception("Invalid directory: $localPath");
    chdir($localPath);
    $directory = opendir(".");
    while ($file = readdir($directory)) {
        if (in_array($file, $this->blackList)) continue;
        if (is_dir($file)) {
            $errorList["$remotePath/$file"] = $this->make_directory("$remotePath/$file");
            $errorList[] = $this->recurse_directory($rootPath, "$localPath/$file", "$remotePath/$file");
            chdir($localPath);
        } else {
            $errorList["$remotePath/$file"] = $this->put_file("$localPath/$file", "$remotePath/$file");
        }
    }
    return $errorList;
}

public function make_directory($remotePath) {
    $error = "";
    try {
        ftp_mkdir($this->connectionID, $remotePath);
    } catch (Exception $e) {
        if ($e->getCode() == 2) $error = $e->getMessage(); 
    }
    return $error;
}

public function put_file($localPath, $remotePath) {
    $error = "";
    try {
        ftp_put($this->connectionID, $remotePath, $localPath, FTP_BINARY); 
    } catch (Exception $e) {
        if ($e->getCode() == 2) $error = $e->getMessage(); 
    }
    return $error;
}
}
