本文实例讲述了php计算给定时间之前的函数用法。分享给大家供大家参考。具体如下:
这里给定一个时间,计算这个时间在多久前,比如:2天前,1年前
<?phpfunction prettyDate($date){ $time = strtotime($date); $now = time(); $ago = $now - $time; if($ago < 60){ $when = round($ago); $s = ($when == 1)?"second":"seconds"; return "$when $s ago"; }elseif($ago = 3600 && $ago = 86400 && $ago = 2629743.83 && $ago < 31556926){ $when = round($ago / 60 / 60 / 24 / 30.4375); $m = ($when == 1)?"month":"months"; return "$when $m ago"; }else{ $when = round($ago / 60 / 60 / 24 / 365); $y = ($when == 1)?"year":"years"; return "$when $y ago"; }}echo prettyDate("2012-07-22 12:23:45")."<br />";echo prettyD<p>+本文来源gao!%daima.com搞$代*!码9网(</p><strong>搞gaodaima代码</strong>ate("2010-11-12 22:25:45")."<br />";echo prettyDate("2012-01-01 01:00:00")."<br />";echo prettyDate("2001-05-30 00:00:00")."<br />";
希望本文所述对大家的php程序设计有所帮助。
