How can blockwise data retrieval be implemented in PHP to prevent timeout issues?

Blockwise data retrieval can be implemented in PHP by fetching data in smaller chunks or blocks, processing each block, and then fetching the next block until all data is retrieved. This prevents timeout issues by breaking down the retrieval process into smaller, manageable tasks that can be completed within the timeout limit.

// Set the block size for data retrieval
$blockSize = 1000;

// Initialize offset for data retrieval
$offset = 0;

// Retrieve data in blocks until all data is fetched
do {
    $data = fetchData($offset, $blockSize);
    
    // Process data here
    
    $offset += $blockSize;
} while (!empty($data));

function fetchData($offset, $limit) {
    // Code to fetch data from database or API
    // Use $offset and $limit to retrieve data in blocks
    // Return fetched data
}
