php计算几分钟前发贴子

php中时间轴开发，即显示为"刚刚"、"5分钟前"、"昨天10:23"等,有需要的朋友可以参考一下。

<?php
function tranTime($time) {
    $rtime = date("m-d H:i", $time);
    $htime = date("H:i", $time);
    $time = time() - $time;
    if ($time < 60) {
        $str = &#39;刚刚&#39;;
    } elseif ($time < 60 * 60) {
        $min = floor($time / 60);
        $str = $min . &#39;分钟前&#39;;
    } elseif ($time < 60 * 60 * 24) {
        $h = floor($time / (60 * 60));
        $str = $h . &#39;小时前 &#39; . $htime;
    } elseif ($time < 60 * 60 * 24 * 3) {
        $d = floor($time / (60 * 60 * 24));
        if ($d == 1) $str = &#39;昨天 &#39; . $rtime;
        else $str = &#39;前天 &#39; . $rtime;
    } else {
        $str = $rtime;
    }
    return $str;
}
?>

函数tranTime()中的参数$time必须为Unix时间戳，如果不是请先用strtotime()将其转换成Unix时间戳

调用代码如下:$times="1286861696 ";echo tranTime($times);
