php - 如何制作一个 PHP 时间类

Question

我想创建一个 PHP 类，它可以从数据库收集信息并检查执行该特定操作的时间，基于它应该能够告诉我该操作是在 10 分钟前、2 天前或 3 年前执行的以前，我做了一个 PHP 类，但有时它返回负时间，我检查并交叉检查它似乎没有任何问题，请我需要帮助

<?php
class ClassTimeFormat{
    protected $dateTime;

    public function __construct($dateTime){

不需要上课。如果您的时间为负数，则您可能以错误的方式减去了时间。

在这段代码中，$intTime 只是来自 time()

function makeNiceTime($intTime)
{
     $curTime = time();
     $strTime = '';
     if ( ($curTime-$intTime) <  (60)) //(24*60*60))
     {
        $strTime = sprintf("%d seconds ago", $curTime-$intTime);
     }
     else if ( ($curTime-$intTime) <  (60*60)) //(24*60*60))
     {
        $strTime = sprintf("%d minutes ago", ($curTime-$intTime) / 60 );
     }
     else if ( ($curTime-$intTime) <  (60*60*24)) //(24*60*60))
     {
        $strTime = sprintf("%d hours ago", ($curTime-$intTime) / (60*60) );
     }
     else if ( ($curTime-$intTime) <  (60*60*24*7)) //(24*60*60))
     {
        $strTime = sprintf("%d days ago", ($curTime-$intTime) / (60*60*24) );
     }
     else
     {  // sample: "12.22 am Sat 21-Jul 2012"
        $strTime = date("g.i a D j-M Y", $intTime);
     }
     return $strTime;
}
