1、在頁頭使用date_default_timezone_set()設置我的默認時區為北京時間，即 <?php date_default_timezone_set("PRC"); ?>就可以了。
2、在php.ini中設置date.timezone的值為PRC，設置好以後的為：date.timezone=PRC，同時取消這一行代碼的註釋，即去掉前面的分號就可以了。
在寫php文件上傳程序時有時會出現這樣的警告：
這是因為PHP所取的時間是格林威治標準時間，所以和你當地的時間會有出入格林威治標準時間和北京時間大概差8個小時左右，我們可以按照下面的方法解決：Upload: 屏幕截圖2014-09-28_160214.png Type: image/png Size: 66.84765625 Kb Temp file: D:\Users\Aven\AppData\Local\Temp\php742F.tmp Warning: move_uploaded_file() [function.move-uploaded-file]: It is not safe to rely on the system‘s timezone settings.

這裏選用修改配置文件的方式解決問題：
用Notepad++打開php.ini,
查找“date.timezone”，把語句前的分號去掉，值設置為“PRC”，重啟FastCGI服務，問題解決。
