来自腾讯微博iweibo2.0更友好的时间格式如“3分钟前”

php代码

/**
 * timestamp转换成显示时间格式
 * @param $timestamp
 * @return unknown_type
 */
function tTimeFormat($timestamp)
{
	$curTime = time();
	$space = $curTime - $timestamp;
	//1分钟
	if($space < 60)
	{
		$string = "刚刚";
		return $string;
	}
	elseif($space < 3600) //一小时前
	{
		$string = floor($space / 60) . "分钟前";
		return $string;
	}
	$curtimeArray = getdate($curTime);
	$timeArray = getDate($timestamp);
