判断信息发布时间距现在的时间差，转换显示成“刚刚”、“几分钟前”、“几小时前”、“昨天”、“前天”。
代码如下：
<?php
/**

date_default_timezone_set('PRC');
$date = "1351836000";
echo tranTime($date);
function tranTime($time)
{
$rtime = date("m-d H:i",$time);
$htime = date("H:i",$time);
$time = time() - $time;
if ($time < 60)
{
$str = '刚刚';
}
elseif ($time < 60 * 60)
{
$min = floor($time/60);
$str = $min.'分钟前';
}
elseif ($time < 60 * 60 * 24)
{
$h = floor($time/(60*60));
$str = $h.'小时前 '.$htime;
}
elseif ($time < 60 * 60 * 24 * 3)
{
$d = floor($time/(60*60*24));
if($d==1)
$str = '昨天 '.$rtime;
else
$str = '前天 '.$rtime;
}
else
{
$str = $rtime;
}
return $str;
}
