How can you calculate the number of days from a timestamp difference in PHP?

To calculate the number of days from a timestamp difference in PHP, you can first convert the timestamps to Unix timestamps using the strtotime() function. Then, calculate the difference between the two Unix timestamps and divide it by the number of seconds in a day (86400) to get the number of days. 

$timestamp1 = strtotime('2022-01-01');
$timestamp2 = strtotime('2022-01-10');

$daysDifference = floor(($timestamp2 - $timestamp1) / 86400);

echo "Number of days difference: ".$daysDifference;
