Ecshop安裝過程中的的問題：cls_image::gd_version()和不支持JPEG

在安裝Ecshop的時候，遇到兩個問題：

1.Strict Standards: Non-static method cls_image::gd_version() should not be called statically in D:/X/www/ecshop/install/includes/lib_installer.php on line 31

解決：找到install/includes/lib_installer.php中的第31行 return cls_image::gd_version();然后在找到include/cls_image.php中的678行，發現gd_version()方法未聲明靜態static，所以會出錯。這時候只要：

1）將function gd_version()改成static function gd_version()即可。

2）或者將install/includes/lib_installer.php中的第31行return cls_image::gd_version();改成：

$p = new cls_image();

return $p->gd_version();

2.檢測環境的時候提示：是否支持 JPEG是不支持的。

解決：查看發現有libjpeg.lib庫，GD2庫也有，都加載了，也都正常。查看ecshop源代碼發現install/includes/lib_installer.php中第100行,JPEG寫成了JPG，正確的應該是：

$jpeg_enabled = ($gd_info['JPEG Support'] === true) ? $_LANG['support'] : $_LANG['not_support'];

為何說Ecshop寫錯了，因為我打印數組$gd_info的時候，里面的鍵名是：JPEG Support。而$gd_info數組里的值都是直接調用系統環境變量的。

3.默認時區問題：Warning: date_default_timezone_get(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in D:/X/www/ecshop/install/includes/lib_installer.php on line 225

解決：方法1，將php.ini里是date.timezone前的";"去掉，改成：date.timezone = PRC;

方法2，在頁頭使用 ini_set('date.timezone','Asia/Shanghai');

方法3，在頁頭使用date_default_timezone_set()設置 date_default_timezone_set('PRC'); //東八時區 echo date('Y-m-d H:i:s');
