How can server speed affect the successful download of files in PHP scripts, and what steps can be taken to address this issue?

Server speed can affect the successful download of files in PHP scripts by causing slow response times or timeouts, leading to incomplete or failed downloads. To address this issue, you can optimize the server configuration, use caching mechanisms, or implement file chunking to download large files in smaller parts. 

// Example of implementing file chunking to download large files in smaller parts
$file = 'path/to/large/file.zip';
$chunkSize = 1024 * 1024; // 1MB chunk size

header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . basename($file) . '"');

$handle = fopen($file, 'rb');
while (!feof($handle)) {
    echo fread($handle, $chunkSize);
    ob_flush();
    flush();
}
fclose($handle);
