這篇文章主要介紹了PHP時間類完整執行個體,涉及PHP針對日期、時間、星期等的擷取與比較等操作技巧,非常簡單實用,需要的朋友可以參考下

本文執行個體講述了PHP時間類。分享給大家供大家參考,具體如下:

<?phpheader("Content-type:text/html;Charset=utf-8");class time{ private $year;//年 private $month;//月 private $day;//天 private $hour;//小時 private $minute;//分鐘 private $second;//秒 private $microtime;//毫秒 private $weekday;//星期 private $longDate;//完整的時間格式 private $diffTime;//兩個時間的差值 //返回年份 time:時間格式為時間戳記  2013-3-27 function getyear($time="",$type=""){ if($time==""){  $time=time(); } if($type==1){  return $this->year=date("y",$time); //返回兩位的年份 13 }else{  return $this->year=date("Y",$time); //返回四位的年份 2013 } } //返回目前時間的月份 time:時間格式為時間戳記 2013-3-27 function getmonth($time="",$type=""){ if($time==""){  $time=time(); } switch($type){  case 1:$this->month=date("n",$time);//返回格式 3   break;  case 2:$this->month=date("m",$time);//返回格式 03   break;  case 3:$this->month=date("M",$time);//返回格式 Mar   break;  case 4:$this->month=date("F",$time);//返回格式 March   break;  default:$this->month=date("n",$time); } return $this->month;  } //返回目前時間的天數 time:時間格式為時間戳記 2013-3-4  function getday($time="",$type=""){ if($time==""){  $time=time(); } if($type==1){  $this->day=date("d",$time);//返回格式 04 }else{  $this->day=date("j",$time);//返回格式 4 } return $this->day; } //返回目前時間的小時  2010-11-10 1:19:21 20:19:21  function gethour($time="",$type=""){ if($time==""){  $time=time(); }  switch($type){  case 1:$this->hour=date("H",$time);//格式: 1 20   break;  case 2:$this->hour=date("h",$time);//格式  01 08   break;  case 3:$this->hour=date("G",$time);//格式  1 20   break;  case 4:$this->hour=date("g",$time);//格式  1 8   break;   default :$this->hour=date("H",$time); } return $this->hour; } //返回目前時間的分鐘數 1:9:18   function getminute($time="",$type=""){ if($time==""){  $time=time(); } $this->minute=date("i",$time); //格式  09 return $this->minute; } //返回目前時間的秒數  20:19:01 function getsecond($time="",$type=""){ if($time==""){  $time=time(); } $this->second=date("s",$time); //格式  01 return $this->second; } //返回目前時間的星期數  function getweekday($time="",$type=""){ if($time==""){  $time=time();  } if($type==1){  $this->weekday=date("D",$time);//格式  Sun }else if($type==2){  $this->weekday=date("l",$time); //格式 Sunday }else{  $this->weekday=date("w",$time);//格式 數字表示 0--6 } return $this->weekday; } //比較兩個時間的大小 格式 2013-3-4 8:4:3   function compare($time1,$time2){ $time1=strtotime($time1); $time2=strtotime($time2); if($time1>=$time2){  //第一個時間大於等於第二個時間 返回1 否則返回0  return 1; }else{  return -1; } } //比較兩個時間的差值 function diffdate($time1="",$time2=""){ //echo $time1.'------'.$time2.'<br>'; if($time1==""){  $time1=date("Y-m-d H:i:s");  } if($time2==""){   $time2=date("Y-m-d H:i:s");  } $date1=strtotime($time1); $date2=strtotime($time2); if($date1>$date2){  $diff=$date1-$date2;  }else{  $diff=$date2-$date1; } if($diff>=0){  $day=floor($diff/86400);  $hour=floor(($diff%86400)/3600);  $minute=floor(($diff%3600)/60);  $second=floor(($diff%60));  $this->diffTime='相差'.$day.'天'.$hour.'小時'.$minute.'分鐘'.$second.'秒';  } return $this->diffTime; } //返回 X年X月X日 function buildDate($time="",$type=""){ if($type==1){     $this->longDate = $this->getyear($time) . '年' . $this->getmonth($time) . '月' . $this->getday($time) . '日';   }else{  $this->longDate = $this->getyear($time) . '年' . $this->getmonth($time) . '月' . $this->getday($time) .
