php中把美国时间转为北京时间的自定义函数分享,美国北京时间
由于最近做邮件系统用到了时间转化,需要把从谷歌gmail下载下来的邮件时间转化为北京时间,于是乎就写了一个时间转化函数,希望对有需要的盆友所有启迪,我们都知道中美时间相差13个小时,下面直接上代码:
function datezhuanhuan($dateparams) { $ccc=strtotime($dateparams); $date=date(‘Y-m-d'); $bjtime=date(‘Y-m-d',$ccc); if($date==$bjtime) { $sbjtime=date(‘Y-m-d H:i:s',$ccc); echo substr($sbjtime,11,5); } else { $sbjtime=date(‘Y-m-d H:i:s',$ccc); return substr($sbjtime,5,5); } }
另一种+8小时的算法:
$bj_time = date ("Y-m-d H:i:s" , mktime(gmdate('H')+8,gmdate('i'),gmdate('s'),gmdate('m'),gmdate('d'),gmdate('Y')));
给他个默认值
例如:function check($aa,$bb=0){ }
后者就为选填了
如果你有服务器的控制权就将服务器的时间调整一下
PHP的我晓得
1.如果你用的软件可以设置时区,那么请通过软件设置。譬如DZ, phpWind, vBulletin等都有此功能。
2.如果你的软件不可以设置时区,你可以通过修改空间的 .htaccess文件
打开你的 .htaccess文件,加入这一样文字
代码:
SetEnv TZ location
location根据你要的不同地区设置,全部时区可以在这里找到 www.php.net/manual/en/timezones.php
譬如你要设置为美国亚特兰大时间,语法写成这样就可以了:
代码:
SetEnv TZ America/Atlanta
