這篇文章主要介紹了php計算時間幾分鐘前、幾小時前、幾天前的幾個函數、類分享,需要的朋友可以參考下
一、函數實現 實例1: 代碼如下: function time_tran($the_time){ $now_time = date("Y-m-d H:i:s",time()+8*60*60); $now_time = strtotime($now_time); $show_time = strtotime($the_time); $dur = $now_time - $show_time; if($dur < 0){ return $the_time; }else{ if($dur < 60){ return $dur.'秒前'; }else{ if($dur < 3600){ return floor($dur/60).'分鐘前'; }else{ if($dur < 86400){ return floor($dur/3600).'小時前'; }else{ if($dur < 259200){//3天內 return floor($dur/86400).'天前'; }else{ return $the_time; } } } 實例2: 代碼如下:<?php function format_date($time){ $t=time()-$time; $f=array( '31536000'=>'年', '2592000'=>'個月', '604800'=>'星期', '86400'=>'天', '3600'=>'小時', '60'=>'分鐘', '1'=>'秒' ); foreach ($f as $k=>$v) { if (0 !=$c=floor($t/(int)$k)) { return $c.$v.'前'; } } } ?> 實例3: 代碼如下: function formatTime($date) { $str = ''; $timer = strtotime($date); $diff = $_SERVER['REQUEST_TIME'] - $timer; $day = floor($diff / 86400); $free = $diff % 86400; if($day > 0) { return $day."天前"; }else{ if($free>0){ $hour = floor($free / 3600); $free = $free % 3600; if($hour>0){ return $hour."小時前"; }else{ if($free>0){ $min = floor($free / 60); $free = $free % 60; if($min>0){ return $min."分鐘前"; }else{ if($free>0){ return $free."秒前"; }else{ return '剛剛'; } } }else{ return '剛剛'; } } }else{ return '剛剛'; } } } 實例4: 代碼如下: function time_tran($the_time){ $now_time = date("Y-m-d H:i:s",time()+8*60*60); $now_time = strtotime($now_time); $show_time = strtotime($the_time); $dur = $now_time - $show_time; if($dur < 0){ return $the_time; }else{ if($dur < 60){ return $dur.'秒前'; }else{ if($dur < 3600){ return floor($dur/60).'分鐘前'; }else{ if($dur < 86400){ return floor($dur/3600).'小時前'; }else{ if($dur < 259200){//3天內 return floor($dur/86400).'天前'; }else{ return $the_time; } } } } } } 二、類的實現 代碼如下:<?php /* * author: Solon Ring * time: 2011-11-02 * 發博時間計算(年,月,日,時,分,秒) * $createtime 可以是當前時間 * $gettime 你要傳進來的時間 */ class Mygettime{ function __construct($createtime,$gettime) { $this->createtime = $createtime; $this->gettime = $gettime; } function getSeconds() { return $this->createtime-$this->gettime; } function getMinutes() { return ($this->createtime-$this->gettime)/(60); } function getHours() { return ($this->createtime-$this->gettime)/(60*60); } function getDay() { return ($this->createtime-$this->gettime)/(60*60*24); } function getMonth() { return ($this->createtime-$this->gettime)/(60*60*24*30); } function getYear() { return ($this->createtime-$this->gettime)/(60*60*24*30*12); } function index() { if($this->getYear() > 1) { if($this->getYear() > 2) { return date("Y-m-d",$this->gettime); exit(); } return intval($this->getYear())." 年前"; exit(); } if($this->getMonth() > 1) { return intval($this->getMonth())." 月前"; exit(); } if($this->getDay() > 1) { return intval($this->getDay())." 天前"; exit(); } if($this->getHours() > 1) { return intval($this->getHours())." 小時前"; exit(); } if($this->getMinutes() > 1) { return intval($this->getMinutes())." 分鐘前"; exit(); } if($this->getSeconds() > 1) { return intval($this->getSeconds()-1)." 秒前"; exit(); } } } //類的使用實例 /* * * 調用類輸出方式 * * $a = new Mygettime(time(),strtotime('-25 month')); * echo iconv('utf-8', 'gb2312', $a->index())?iconv('utf-8', 'gb2312', $a->index()):iconv('utf-8', 'gb2312', '當前'); * */
