How can PHP scripts effectively manage the processing of large datasets with varying execution times?

When processing large datasets with varying execution times in PHP scripts, it is important to break down the processing into smaller chunks or batches. This can help prevent memory issues and timeouts, as well as allow for better error handling and monitoring. One approach is to use a loop to iterate over the dataset in smaller portions, processing each chunk separately. 

// Example code snippet to process large dataset in batches
$dataset = // large dataset to process

$batchSize = 100; // define the size of each batch
$totalItems = count($dataset);
$processedItems = 0;

while($processedItems < $totalItems){
    $batch = array_slice($dataset, $processedItems, $batchSize); // get a chunk of data
    // process the batch
    foreach($batch as $item){
        // process each item in the batch
    }
    $processedItems += $batchSize;
}
