Question

我想创建一个PHP类，它可以从数据库中收集信息并检查该特定操作的执行时间，因为它应该能够告诉我该操作是在10分钟前或2天前执行的，或者3年前，我做了一个PHP课程，但有时它返回负片时间，我检查并交叉检查它似乎没有任何错误，请我需要帮助

<?php
class ClassTimeFormat{
    protected $dateTime;

    public function __construct($dateTime){
        $this->dateTime =   $dateTime;
    }

    public function getYears(){
         $sql=  " SELECT YEAR('$this->dateTime') as year";
         $result    =   mysql_query($sql) or die(mysql_error());
         $row   =   mysql_fetch_assoc($result) or die(mysql_error());
         return $row['year'];
    }

    public function getDayofMonth(){
        $sql    =   "SELECT DAY('$this->dateTime') as day";
        $result =   mysql_query($sql) or die(mysql_error());
        $row    =   mysql_fetch_assoc($result);

不需要上课。如果你的时间是负数，你可能已经错误地减去了时间。

在这段代码中，$ intTime只来自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;
}
