How can large arrays in PHP be efficiently managed to prevent database size issues?

Large arrays in PHP can lead to memory issues and potential performance problems, especially when dealing with database results. To prevent database size issues, it's essential to efficiently manage these arrays by using techniques like pagination or limiting the number of records fetched at once. By fetching and processing data in smaller chunks, you can reduce memory consumption and improve overall performance. 

// Example of efficiently managing large arrays in PHP to prevent database size issues
$limit = 100; // Number of records to fetch at a time
$offset = 0; // Initial offset

while(true) {
    $results = fetchDataFromDatabase($limit, $offset); // Function to fetch data from database
    if(empty($results)) {
        break; // Exit loop if no more records
    }

    // Process fetched data here

    $offset += $limit; // Increment offset for next iteration
}

function fetchDataFromDatabase($limit, $offset) {
    // Code to fetch data from database with LIMIT and OFFSET
    // Return fetched results as an array
}
