Relative Dates

In this tutorial I am going to teach you how to create your own relative date function.

We will use full relative dates like '1 minute ago', '1 hour ago' etc, but we will have exceptions for the time and a full date.

We start off creating a function, let's call it get_date. It should have two parameters, the time (unix time stamp) value and the type.

CODE:

Next up, calculating how many seconds are minutes, hours, days and weeks, transform the $timestamp into a relative date format and put the result in $returndate.

We all know that an hour has 3600 seconds, so if the diffrence is below 3600 we calculate in minutes. If the differnce is below 120, the returndate is 1 minute ago.
The calculation is done by dividing $timediff by 60.

CODE:

If the diffrence is less than 86400, we can't be over one day, so we calculate in hours. The calculation is done by dividing $timediff by 3600.

CODE:

Next up: calculating the days. If the diffrence is less than 604800, means we're not at one week yet, so let's calculate in days. The calculation is $timediff / 86400.

CODE:

Now we need to calculate the weeks, let's stop at 4 weeks. The calculation is $timediff divided by 604900.

CODE:

Now to finish it off, let's convert the date to normal date if the diffrence is over 3024000. Also, we will parse our special types of dates.

CODE:

Almost done, close the function with a }.

CODE:

Now to use this function do the following:

CODE:
