This article mainly introduced the PHP real-time Countdown function realization method, combined with the concrete instance form analysis PHP with the foreground JS timestamp operation to realize the countdown function specific steps and the related operation skill, needs the friend can refer to the next
In this paper, the implementation of PHP real-time countdown

Scene: send a verification code to the phone, when the verification code is issued, will be prompted to send again after 1 minutes. Usually there are several ways to prevent malicious requests, one is to send the verification code before sending again, and the second is not to send again within the specified time interval. Some websites are sent within a 1 minute interval between the Send button is indeed disabled, but as long as the browser refresh,
The received parameter end is a must pass, the format is a/delimited date string, start is optional, does not pass the countdown from now on, callback is also optional, to the countdown to execute the custom function.Countdown ({ ' end ': ' 2015/9/1 17:12:00 ', ' callback ':function () { document.getElementById (' countd

1. First, you must set a date attribute in the background to the pre-sale date.
2. Then retrieve the property value $ _ product-> getresource ()-> getattribute ('code')-> getfrontend ()-> getvalue ($ _ product );
A string-type time data is retrieved. You need to use the strtotime () function to convert the time into a timestamp, and then get the current time. the subtraction of the two is the countdown second
About the implementation of the countdown to Android, for many people has been a headache, of course, I also, in the development countdown function will encounter a lot of difficult or even exotic problems or bugs, I in the development countdown, if the current page only a countdown, then it is not very complicated, Th
Requirements:
1, to have an hour minute seconds of the real-time countdown display.
2, the user-side modification date time does not affect the countdown to the normal display (that is, the server time is the subject). In fact, this is the same as many examinations and other system time-limited function requirements.
Solution Ideas:

Countdown js Code
