PHP：获取一年中的最后一位数（例如：2015 == 5）

Question

How may I convert my function to show the last and/or the second last digit in the "Y" tag?

Here is my code:

<?php
$timestamp = time();     //Timestamp from server
$user_time = 1597429549; //Timestamp from database

$time = ($user_time-$timestamp); // Should be around 4 years

echo gmdate("Y m d H i s", $time); //This will output 1974 10 20 19 59 34
?>

How can I convert this to display time as:

4 10 20 19 59 34 or 0004 10 20 19 59 34

Instead of:

1974 10 20 19 59 34

Answer 1

Use modulus operator:

2015 % 10 = 5
