What are some best practices for handling large amounts of data in PHP when writing to a file?

When handling large amounts of data in PHP when writing to a file, it is important to consider memory usage and performance. One way to handle this is by writing data in chunks rather than all at once. This can help reduce memory usage and improve performance when dealing with large datasets. 

$data = // large amount of data to write to file
$chunkSize = 1000; // define the chunk size

$file = fopen('output.txt', 'w'); // open file for writing

foreach (array_chunk($data, $chunkSize) as $chunk) {
    fwrite($file, implode(',', $chunk) . PHP_EOL); // write chunk to file
}

fclose($file); // close file
