Create a Countdown Timer for Websites With PHP Mktime

Create a Countdown Timer for Websites With PHP Mktime Because the ist_dst parameter used in this example was deprecated in PHP 5.1 and removed in PHP 7, it is not safe to rely on this  code to deliver accurate results in current versions of PHP. Instead, use the date.timezone setting or the date_default_timezone_set() function. If your webpage focuses on a specific event in the future such as Christmas or your wedding, you may want to have a countdown timer to let users know how long it is until the event occurs. You can do this in PHP using timestamps and the mktime function. The  mktime() function is used to artificially generate the timestamp for a selected date and time. It works the same as the time() function, except it is for a specified date and not necessarily todays date. How to Code the Countdown Timer Set a target date. For  example, use February 10th, 2017. Do that with this line, which follows the syntax :  mktime(hour,minute,second,month,day,year: ist _dst). $target mktime(0, 0, 0, 2, 10, 2017) ;Establish the current date with this line: $today time () ;To find the difference between the two dates, simply subtract: $difference ($target-$today) ;Since the timestamp is measured in seconds, convert the results into whatever units you want. For hours, divide by 3600. This  example uses days so divide by 86,400- the number of seconds in a day. To make sure the number is an integer, use the tag int. $days (int) ($difference/86400) ;Put it all together for the final code: ?php $target mktime(0, 0, 0, 2, 10, 2017) ; $today time () ; $difference ($target-$today) ; $days (int) ($difference/86400) ; print Our event will occur in $days days; ?
