What are the best practices for handling batch processes, such as reading and processing multiple files, in PHP to ensure smooth execution and avoid script timeouts?

When handling batch processes in PHP, it is important to break down the processing into smaller chunks to prevent script timeouts and ensure smooth execution. One way to achieve this is by using a combination of file iteration and processing in smaller batches.

// Set the maximum execution time to unlimited
set_time_limit(0);

// Get a list of files to process
$files = glob('path/to/files/*.txt');

// Process files in batches
$batchSize = 10; // Number of files to process in each batch
$totalFiles = count($files);

for ($i = 0; $i < $totalFiles; $i += $batchSize) {
    $batchFiles = array_slice($files, $i, $batchSize);

    foreach ($batchFiles as $file) {
        // Process the file here
    }
}
