For calculating the first dayof next month from today:

$firstDayNextMonth = date('Y-m-d', strtotime('first day of next month'));

How to calculate the first day of next quarter from today?

• First quarter, Q1: 1 January – 31 March


• Second quarter, Q2: 1 April – 30 June


• Third quarter, Q3: 1 July – 30 September


• Fourth quarter, Q4: 1 October – 31 December

Thank you!

My Answer:
To calculate the first day of next quarter from today in PHP, you can use the following code:

php
$currentMonth = date('n');
$currentQuarter = ceil($currentMonth / 3);
$nextQuarter = ($currentQuarter % 4) + 1;

$nextQuarterStartMonth = ($nextQuarter - 1) * 3 + 1;
$nextQuarterStartDate = date('Y-m-d', strtotime('first day of ' . $nextQuarterStartMonth . ' month'));

echo $nextQuarterStartDate;


This code calculates the current quarter based on the current month, then determines the next quarter. It then calculates the start month of the next quarter and uses it to find the first day of that quarter.
