How can PHP be optimized for handling large JSON files for database updates via Cron jobs?

Handling large JSON files for database updates via Cron jobs in PHP can be optimized by using batch processing to avoid memory issues. One way to achieve this is by reading the JSON file line by line and processing a certain number of records at a time. This approach helps in efficiently updating the database without overwhelming the server's memory. 

<?php
// Read the JSON file line by line
$handle = fopen('large_file.json', 'r');
while (!feof($handle)) {
    $line = fgets($handle);
    
    // Process the JSON data
    $data = json_decode($line, true);
    
    // Update the database with the processed data
    // Perform database operations here
    
    // Limit the number of records processed per batch
    // For example, update 100 records at a time
    if ($batchCount == 100) {
        // Commit changes to the database
        // Reset the batch count
        $batchCount = 0;
    }
}
fclose($handle);
?>
