What are some best practices for handling date sorting and manipulation in PHP when working with CSV files?

When working with CSV files in PHP, it is important to properly handle date sorting and manipulation to ensure accurate data processing. One best practice is to use PHP's DateTime class to parse and format dates in the CSV file. This allows for easy comparison and manipulation of dates within the script. 

// Example of sorting dates in a CSV file using PHP

// Read the CSV file into an array
$csvData = array_map('str_getcsv', file('data.csv'));

// Sort the array based on the date column (assuming date is in the second column)
usort($csvData, function($a, $b) {
    $dateA = new DateTime($a[1]);
    $dateB = new DateTime($b[1]);
    return $dateA <=> $dateB;
});

// Output the sorted data
foreach ($csvData as $row) {
    echo implode(',', $row) . PHP_EOL;
}
