What are some best practices for handling large data processing tasks in PHP to avoid script interruptions or unexpected behavior?

When handling large data processing tasks in PHP, it is important to avoid script interruptions or unexpected behavior by breaking down the processing into smaller chunks and using appropriate memory management techniques. One common approach is to use batch processing, where data is processed in smaller batches to prevent memory overload and script timeouts.

// Example of batch processing to handle large data tasks in PHP

// Set the batch size
$batchSize = 100;

// Retrieve data to process
$dataToProcess = getDataToProcess();

// Split data into batches
$batches = array_chunk($dataToProcess, $batchSize);

// Process each batch
foreach ($batches as $batch) {
    // Process data in the batch
    processBatch($batch);
}

// Function to retrieve data to process
function getDataToProcess() {
    // Retrieve data from database or other source
    return $dataToProcess;
}

// Function to process a batch of data
function processBatch($batch) {
    // Process data in the batch
    foreach ($batch as $data) {
        // Perform processing tasks
    }
}
