What considerations should be made when managing large amounts of data for statistical purposes in PHP applications?

When managing large amounts of data for statistical purposes in PHP applications, it's important to consider memory usage and performance. One approach to handle this is to process the data in chunks rather than all at once to avoid memory exhaustion. Additionally, using optimized data structures and algorithms can help improve efficiency when working with large datasets. 

// Example of processing data in chunks
$chunkSize = 1000;
$totalRows = count($data);
for ($i = 0; $i < $totalRows; $i += $chunkSize) {
    $chunk = array_slice($data, $i, $chunkSize);
    
    // Perform statistical calculations on the chunk of data
    // ...
}
