PHP Calculates date interval days

How do I use PHP to calculate date interval days? This paper mainly introduces the method of PHP using Strtotime to calculate the number of days between two dates, and analyzes the technique of PHP operation date and time. We hope to help you.

This example describes how PHP uses Strtotime to calculate the number of days between two given dates. Share to everyone for your reference. The specific analysis is as follows:

PHP's Strtotime function is used to parse the datetime description of any English text into a Unix timestamp. This function uses the TZ environment variable (if any) to calculate the timestamp. If the execution succeeds it returns a timestamp, otherwise it returns false. Before PHP 5.1.0, this function will return-1.

$date 1 = date (' y-m-d '), $date 2 = ' 2005-03-01′; $days = (Strtotime () –strtotime ())/(* *); echo "Number of days sin Ce ' 2005-03-01′: $days ";
