php显示文章 几分钟前,几小时前,几天前发布类
文章发表时的UNIX时间戳,来转化为例如,几分钟前,几小时前,几天前....这样的提示,如微博,这看起来更加人性化,类代码如下:
<?php class timeAgo { static $timeagoObject; private $rustle; private $unit; private function __construct() { } private function __clone() { } public static function getObject() { if (!(self::$timeagoObject instanceof self)) self::$timeagoObject = new timeAgo(); return self::$timeagoObject; } private function count_int($unix_C) // main function { if (!(isset($unix_C) || is_numeric($unix_C))) return 'don\'t find parameter'; $d = time() - $unix_C; // $d - unix time difference value $d_int = (int)floor($d / 60); // minimum unit -- minutes unix/60 $this->unit = 0; // is minutes,hour or day? if ($d_int < 60) { // minutes in one hour 3600 $this->rustle = $d_int; $this->unit = 1; } else if ($d_int < 720) { //hour in one day 3600*12 $this->rustle = floor($d_int / 60); $this->unit = 2; } else if ($d_int < 7200) { //day in ten days 3600*12*10 $this->rustle = floor($d_int / 720); $this->unit = 3; } else { $this->rustle = $d; $this->unit = 4; } } public function piece_str($C) { $this->count_int($C); $u = ''; switch ($this->unit) { case 1: $u = 'minute'; break; case 2: $u = 'hour'; break; case 3: $u = 'day'; break; case 4: $u = ''; break; case 0: return 'sorry , get time is fail'; } if ($this->unit < 4) { if ($this->rustle > 1) return (string)$this->rustle . $u . 's ago'; else if ($this->rustle == 1) return (string)$this->rustle . $u . 'ago'; else return 'Just now'; } } /* example: $ago = timeAgo::getObject(); * echo $ago->piece_str($unix); * // 2 days ago */ }
