PHP FTP functions allow you to connect to remote FTP servers and manage files directly from your PHP scripts. You can upload, download, delete, or list files using built-in functions like ftp_connect(), ftp_login(), ftp_put(), and more. These functions are useful for automating file transfers or managing remote servers. FTP must be enabled in your php.ini. Always close the connection using ftp_close() after operations.

1. Connect to FTP Server

<?php
$ftp_server = "ftp.example.com";
$ftp_user = "username";
$ftp_pass = "password";

// Establish connection
$conn = ftp_connect($ftp_server);

// Login
if (@ftp_login($conn, $ftp_user, $ftp_pass)) {
    echo "Connected to FTP server!";
} else {
    echo "FTP login failed!";
}
?>

2. Upload a File

$local_file = "local.txt";
$remote_file = "server.txt";

if (ftp_put($conn, $remote_file, $local_file, FTP_ASCII)) {
    echo "File uploaded successfully.";
} else {
    echo "Upload failed.";
}

3. Download a File

$local_file = "downloaded.txt";
$remote_file = "server.txt";

if (ftp_get($conn, $local_file, $remote_file, FTP_ASCII)) {
    echo "File downloaded successfully.";
} else {
    echo "Download failed.";
}

4. List Files in Directory

$files = ftp_nlist($conn, ".");
print_r($files);

5. Delete a File

if (ftp_delete($conn, "old_file.txt")) {
    echo "File deleted.";
} else {
    echo "Delete failed.";
}

6. Close Connection

ftp_close($conn);
