By passing in the UNIX timestamp of the article stored in the database when it was published, it will be converted into prompts such as minutes ago, hours ago, and days ago. For example, Weibo

This looks more user-friendly, okay, let’s go to the code

The code is as follows:

<?php 
class timeAgo 
{ 
static $timeagoObject; 
private $rustle; 
private $unit; 
private function construct() 
{ 
} 
private function clone(){ } 
public static function getObject() 
{ 
if(! (self::$timeagoObject instanceof self) ) 
self::$timeagoObject = new timeAgo(); 
return self::$timeagoObject; 
} 
private function count_int($unix_C) // main function 
{ 
if(! (isset($unix_C) || is_numeric($unix_C)) ) 
return &#39;don\&#39;t find parameter&#39;; 
$d = time()-$unix_C ; // $d - unix time difference value 
$d_int =(int)floor($d/60) ; // minimum unit -- minutes unix/60 
$this->unit = 0 ; // is minutes,hour or day? 
if($d_int < 60){ // minutes in one hour 3600 
$this->rustle = $d_int; 
$this->unit = 1; 
} 
else if($d_int < 720){ //hour in one day 3600*12 
$this->rustle = floor($d_int/60); 
$this->unit = 2 ; 
} 
else if($d_int < 7200){ //day in ten days 3600*12*10 
$this->rustle = floor($d_int/720); 
$this->unit = 3 ; 
} 
else{ 
$this->rustle = $d ; 
$this->unit = 4 ; 
} 
} 
public function piece_str($C) 
{ 
$this->count_int($C); 
$u = &#39;&#39;; 
switch( $this->unit ) 
{ 
case 1: 
$u = &#39;minute&#39;; 
break; 
case 2: 
$u = &#39;hour&#39;; 
break; 
case 3: 
$u = &#39;day&#39;; 
break; 
case 4: 
$u = &#39;&#39;; 
break; 
case 0: 
return &#39;sorry , get time is fail&#39;; 
} 
if($this->unit < 4) 
{ 
if($this->rustle > 1) 
return (string)$this->rustle.$u.&#39;s ago&#39;; 
else if($this->rustle == 1) 
return (string)$this->rustle.$u.&#39;ago&#39;; 
else 
return &#39;Just now&#39;; 
} 
} 
/* example: $ago = timeAgo::getObject(); 
* echo $ago->piece_str($unix); 
* // 2 days ago 
*/ 
} 
?>
