Sometimes, we need to announce something on the website or want to wish any festival to our readers then we need a kind of timer (we can say, it is countdown timer) to be displayed on the website.

In this post, we are writing PHP code that will display a countdown timer for "Diwali" on the webpage.

In this code,

We are using a function strtotime() which is used to artificially generate the timestamp for a selected date and time.
We are defining date and time for festival “Diwali”, which is known as target date time, the value is "2017-10-19 12:00:00.
And, as a current date time we are using now which gives current date and time.
