PHP计算2个不同日期之间的天数[重复]

Hello and thanks for the help. I have a table in mysql with 2 columns (date1),(date2).I want to find the days between these two days and calculate a price of 10 dollars for each day through php

</div>

here you go:

$dt1 = new DateTime("@{$date1}");
$dt2 = new DateTime("@{$date2}");
$interval = $dt1->diff($dt2);
$price = 10 * $interval->d;

This assumes that you are saving your dates $date1and $date2 as unix timestamps

Try this..

<?php
     $first_date = strtotime("2013-04-10");
     $last_date = strtotime("2013-04-01");
     $datediff = $first_date - $last_date;
     echo "Days : ". floor($datediff/(60*60*24))."<br>";
     echo "Price : $". (floor($datediff/(60*60*24)))*10;
?>

Output

Days : 9
Price : $90
