What are the best practices for optimizing memory usage when processing and encoding large amounts of data in PHP?

To optimize memory usage when processing and encoding large amounts of data in PHP, it is important to avoid loading the entire dataset into memory at once. Instead, process the data in smaller chunks to reduce memory usage. Additionally, consider using streaming techniques to handle the data incrementally without storing it all in memory.

// Example of processing and encoding large amounts of data in PHP with reduced memory usage
$largeData = []; // Assume this array contains a large amount of data

// Process and encode data in smaller chunks
$chunkSize = 1000;
$totalChunks = ceil(count($largeData) / $chunkSize);

for ($i = 0; $i < $totalChunks; $i++) {
    $chunk = array_slice($largeData, $i * $chunkSize, $chunkSize);

    // Process and encode the current chunk of data
    // Example: json_encode($chunk);
}
