php转换秒数为时间(年、月、日、小时…)的代码

写了一个函数，将秒数表示的事件转换为年、月、日、小时等时间格式。有需要的朋友，可以参考下。

代码如下：

<?php
/**
 * 秒数转为年月日小时等时间格式 
 * by http://bbs.it-home.org
*/
function Sec2Time($time){ 
  if(is_numeric($time)){ 
    $value = array( 
      "years" => 0, "days" => 0, "hours" => 0, 
      "minutes" => 0, "seconds" => 0, 
    ); 
    if($time >= 31556926){ 
      $value["years"] = floor($time/31556926); 
      $time = ($time%31556926); 
    } 
    if($time >= 86400){ 
      $value["days"] = floor($time/86400); 
      $time = ($time%86400); 
    } 
    if($time >= 3600){ 
      $value["hours"] = floor($time/3600); 
      $time = ($time%3600); 
    } 
    if($time >= 60){ 
      $value["minutes"] = floor($time/60); 
      $time = ($time%60); 
    } 
    $value["seconds"] = floor($time); 
    return (array) $value; 
  }else{ 
    return (bool) FALSE; 
  } 
}
?>
