关于Emlog博客文章时间显示方式几种表达方式

<?php
function sydate($ptime){
	$ptime = strtotime($ptime);
	$etime = time() - $ptime;
	if($etime < 1){return '刚刚';}
	$interval = array(
		12 * 30 * 24 * 60 * 60 => '年前 ('.date('Y-m-d', $ptime).')',
		30 * 24 * 60 * 60      => '个月前 ('.date('Y-m-d', $ptime).')',
		7 * 24 * 60 * 60       => '周前 ('.date('Y-m-d', $ptime).')',
		24 * 60 * 60           => '天前',
		60 * 60                => '小时前',
		60                     => '分钟前',
		1                      => '秒前',
	);
foreach ($interval as $secs => $str) {
		$d = $etime / $secs;
		if ($d >= 1){
			$r = round($d);
			return $r . $str 
		}
	};
}
