日期和今天的PHP差异（显示周）

Question

Ok, here is my problem. Instead of measuring 7 days in seconds, I want to count how many weeks (Sunday Through Saturday) there are from date #1 to today.

PHP

$today1 = date("Y-m-d");  

$diff = strtotime($date1,0) - strtotime($today1,0);
echo (floor($diff / 604800)); 

Answer 1

If you're counting in seconds, why use date() when you can use time() instead- it gives out the numeric time signature of your current time, making calculations such as this much easier.
