PHP显示前天,昨天,今天,几天前

<?php
function tranTime($time) {
    $rtime = date("m-d H:i",$time);
    $rtime2 = date("Y-m-d H:i",$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)
           $str = '昨天 '.$htime;
        else
           $str = '前天 '.$htime;
    } elseif ($time < 60 * 60 * 24 * 7) {
        $d = floor($time/(60*60*24));
           $str = $d.' 天前 '.$htime;
    } elseif ($time < 60 * 60 * 24 * 30) {
        $str = $rtime;
    } else {
        $str = $rtime2;
    }
    return $str;
}
$w_time = time() - 3600;
$times = tranTime($w_time);
echo $times;
?>

 

PHP格式化日期,显示“刚刚,几分钟前,几小时前,几天前,几个月前”

<?php
function format_date($time) {
    $nowtime = time();
    $difference = $nowtime - $time;

    switch ($difference) {

        case $difference <= '60' :
            $msg = '刚刚';
            break;

        case $difference > '60' && $difference <= '3600' :
            $msg = floor($difference / 60) . '分钟前';
            break;

        case $difference > '3600' && $difference <= '86400' :
            $msg = floor($difference / 3600) . '小时前';
            break;

        case $difference > '86400' && $difference <= '2592000' :
            $msg = floor($difference / 86400) . '天前';
            break;

        case $difference > '2592000' &&  $difference <= '7776000':
            $msg = floor($difference / 2592000) . '个月前';
            break;
        case $difference > '7776000':
            $msg = '很久以前';
            break;
    }

    return $msg;
}
?>
