How can PHP scripts be optimized to efficiently handle file uploads and downloads between servers?

To optimize PHP scripts for handling file uploads and downloads between servers, you can use functions like `file_get_contents()` and `file_put_contents()` to efficiently read and write files. Additionally, you can utilize cURL functions for transferring files between servers. Make sure to handle errors and exceptions properly to ensure the reliability of the file transfer process. 

// Example of efficiently handling file uploads using file_get_contents
$fileContent = file_get_contents('http://example.com/file.txt');
file_put_contents('local_file.txt', $fileContent);

// Example of efficiently handling file downloads using cURL
$remoteFile = 'http://example.com/file.txt';
$localFile = 'local_file.txt';

$ch = curl_init($remoteFile);
$fp = fopen($localFile, 'w');

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);
curl_close($ch);
fclose($fp);
