PHP设置时区

gry — Mon, 12 Oct 2009 13:09:01 +0000

PHP中用date获取的是服务器时间，如果你的服务器在中国，就不存在时差问题，如果在美国，就需设置默认时区，用以下代码即可解决。


date_default_timezone_set("PRC");   //将时区设为中国(PRC)
$date=date("Y-m-d H:i:s");
?>

PHP计算时差

gry — Sat, 03 Oct 2009 01:44:43 +0000

计算时差不是件容易的事，因为日期-时间是多种进制混合在一起，需要转换成秒才能计算，比较麻烦，好在PHP提供了一个函数，能把一个时间（1970-2038之间的年）转换为相对 1970.01.01 0:0:0 的相对秒数值，这样就可以直接计算了。
函数格式：mktime(int hour, int minute, int second, int month, int day, int year);
Code（时间用yymmddhhiiss格式，无空格，如：20090123095946）

function calc_shicha($t2,$t1) {
  $y=substr($t1,0,4);$m=substr($t1,4,2);$d=substr($t1,6,2);$h=substr($t1,8,2);$i=substr($t1,10,2);$s=substr($t1,12,2);//分离t1
  $tt1=mktime($h,$i,$s,$m,$d,$y);
  $y=substr($t2,0,4);$m=substr($t2,4,2);$d=substr($t2,6,2);$h=substr($t2,8,2);$i=substr($t2,10,2);$s=substr($t2,12,2);//分离t2
  $tt2=mktime($h,$i,$s,$m,$d,$y);
  return($tt2-$tt1);
};

PHP中设置Session过期的方法

gry — Fri, 02 Oct 2009 01:16:41 +0000

Session的有效期是随浏览器进程的，浏览器关掉后就没了，那么怎么像Cookies那样设置过期时间呢？下面这段代码就可以实现。

^?Download session_cookies.txt


$cookies_life_time = 24 * 3600;   //过期时间，单位为秒，这里的设置即为一天
session_start();
setcookie(session_name() ,session_id(), time() + $cookies_life_time, "/");
?>
