php中将时间差转换为字符串提示的实现代码
前端之家收集整理的这篇文章主要介绍了
php中将时间差转换为字符串提示的实现代码，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
如微博 这看起来更加人性化，好吧，上代码
<div class="codetitle">@L_502_0@ 代码如下:
<div class="codebody" id="code34806">
<?
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 'don\'t find parameter'; $d = time()-$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 360012
10
$this->rustle = floor($d_int/720);
$this->unit = 3 ;
}
else{
$this->rustle = $d ;
$this->unit = 4 ;
}
}
public function piece_str($C)
{

return 'sorry,get time is fail';
}
if($this->unit < 4)

if($this->rustle > 1)
return (string)$this->rustle.$u.'s ago';
else if($this->rustle == 1)
return (string)$this->rustle.$u.'ago';
else

}
}
/ example: $ago = timeAgo::getObject();
echo $ago->piece_str($unix);
