Is there a recommended approach for handling timeouts and ensuring successful downloads of large files in PHP scripts?

When downloading large files in PHP scripts, it is important to handle timeouts properly to ensure successful downloads. One recommended approach is to increase the maximum execution time and memory limit for the script, use the set_time_limit() function to prevent timeouts, and implement error handling to retry the download if it fails. 

// Increase max execution time and memory limit
ini_set('max_execution_time', 0);
ini_set('memory_limit', '512M');

// Set timeout limit
set_time_limit(0);

// URL of the file to download
$url = 'http://example.com/largefile.zip';

// Download the file
$downloadedFile = 'downloaded_file.zip';
$success = false;

$retry = 3;
while ($retry > 0 && !$success) {
    $file = file_get_contents($url);
    
    if ($file !== false) {
        file_put_contents($downloadedFile, $file);
        $success = true;
    } else {
        $retry--;
    }
}

if ($success) {
    echo 'File downloaded successfully!';
} else {
    echo 'Failed to download file after multiple retries.';
}
