How can PHP developers efficiently determine the current quarter in their code to generate dynamic date ranges for MySQL queries?

To efficiently determine the current quarter in PHP, developers can use the date() function to get the current month, and then calculate the quarter based on the month. This can be achieved by dividing the current month by 3 and rounding up to the nearest whole number. Once the quarter is determined, developers can generate dynamic date ranges for MySQL queries based on the start and end dates of the quarter. 

$currentMonth = date('n');
$currentQuarter = ceil($currentMonth / 3);

switch ($currentQuarter) {
    case 1:
        $startDate = date('Y-m-d', strtotime('first day of January'));
        $endDate = date('Y-m-d', strtotime('last day of March'));
        break;
    case 2:
        $startDate = date('Y-m-d', strtotime('first day of April'));
        $endDate = date('Y-m-d', strtotime('last day of June'));
        break;
    case 3:
        $startDate = date('Y-m-d', strtotime('first day of July'));
        $endDate = date('Y-m-d', strtotime('last day of September'));
        break;
    case 4:
        $startDate = date('Y-m-d', strtotime('first day of October'));
        $endDate = date('Y-m-d', strtotime('last day of December'));
        break;
}

echo "Current quarter: Q$currentQuarter\n";
echo "Start date: $startDate\n";
echo "End date: $endDate\n";
