How can we know the number of days between two given dates using PHP?

Answer 1

PHP dont provide any specific function like MySQL. If you are compairing the dates with database then It's recommendated that use the DATEDIFF() function from MySQL cos it's more efficient cos it will give u the diff directly you dont have to process the output for date difference.

Answer 2

(strtotime($date1) - strtotime($date2)) / (60 * 60 * 24);
