确定时间戳是否在50秒前[关闭]

Question

How to know if $database_row_datetime is 50 seconds ago?

For example:

if $database_row_datetime is 50 seconds ago {
    echo "This post was sent now";
}

Here is my timestamp variable:

var_dump($database_row_datetime) => string(19) "2015-04-28 15:20:09"

Answer 1

<?php
if ((time() - strtotime($database_datetime)) < 60) {

This is a quick, dirty solution for one if statement.

The correct way to handle this is with DateTime and DateInterval classes.
