Jak obliczyć liczbę dni w każdym miesiącu w php

Question

trzeba obliczyć liczbę dni od bieżącej daty do 27 dnia każdego miesiąca w PHP W poniższym kodzie obliczane jest poprawnie dla bieżącego miesiąca, ale jeśli bieżąca data to 28. to powinien obliczyć na następny miesiąc.

$year = date("y"); 
$month = date("m"); 
$day = '27'; 

$current_date = new DateTime(date('Y-m-d'), new DateTimeZone('Asia/Dhaka')); 
$end_date = new DateTime("$year-$month-$day", new DateTimeZone('Asia/Dhaka')); 
$interval = $current_date->diff($end_date); 
echo $interval->format('%a day(s)'); 

Answer 1

Napisałem ten skrypt szybko, ponieważ nie mam czasu, aby go przetestować.

EDIT:

$day = 27; 
$today = date('d'); 

if($today < $day){ 
    $math = $day - $today; 
    echo "There are " . $math . " days left until the 27th."; 
} else { 
    $diff = date('t') - $today; 

    $math = $diff + $day; 
    echo "There are " . $math . " days left until the 27th of the next month."; 
}

Answer 4

$now = time(); // or your date as well 
$your_date = strtotime("2010-01-01"); 
$datediff = $now - $your_date; 

echo floor($datediff/(60 * 60 * 24));
