Implementation of converting time difference into string in php

This article mainly introduces the implementation of converting time difference into string in PHP. It has certain reference value. Now I share it with you. Friends in need can refer to it.

Stored by passing it into the database The UNIX timestamp when the article was published can 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

<?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 
*/ 
} 
?>
