How can PHP developers troubleshoot and resolve issues related to FTP connections and file manipulation?

To troubleshoot and resolve FTP connection and file manipulation issues in PHP, developers can check for proper FTP credentials, ensure the FTP server is running, and verify file permissions. Additionally, using PHP functions like ftp_connect, ftp_login, ftp_put, and ftp_get can help in establishing FTP connections and performing file operations. 

// Example code snippet to establish an FTP connection and upload a file
$ftp_server = "ftp.example.com";
$ftp_user = "username";
$ftp_pass = "password";

$ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");

if (ftp_login($ftp_conn, $ftp_user, $ftp_pass)) {
    echo "Connected to $ftp_server";
    
    $local_file = "local_file.txt";
    $remote_file = "remote_file.txt";
    
    if (ftp_put($ftp_conn, $remote_file, $local_file, FTP_ASCII)) {
        echo "File uploaded successfully";
    } else {
        echo "Failed to upload file";
    }
} else {
    echo "Could not login to $ftp_server";
}

ftp_close($ftp_conn);
