What are some common mistakes that beginners make when working with FTP uploads in PHP?

One common mistake beginners make when working with FTP uploads in PHP is not setting the correct permissions for the uploaded files. This can lead to issues with accessing or deleting the files later on. To solve this, make sure to set the correct permissions for the uploaded files using the `ftp_chmod` function after uploading.

// Connect to FTP server
$ftp_server = "ftp.example.com";
$ftp_username = "username";
$ftp_password = "password";
$conn_id = ftp_connect($ftp_server);
ftp_login($conn_id, $ftp_username, $ftp_password);

// Upload file
$local_file = "local_file.txt";
$remote_file = "remote_file.txt";
ftp_put($conn_id, $remote_file, $local_file, FTP_ASCII);

// Set correct permissions for uploaded file
ftp_chmod($conn_id, 0644, $remote_file);

// Close FTP connection
ftp_close($conn_id);
