1. 如何用php得到一個給定IP是屬於哪個國家地區 - 技術問答

純真IP資料庫,能不能說明白點,要不你給我把代碼看一下錯在哪裡.

2. PHP 位運算符

$h=16,$c=4,表達式16<<4的值為256，因為16（即二進制的00010000）向左移四位等於256（即二進制的100000000）

3. centOS 安裝php5.3.28時報錯

解決方法：
1.換成php版本5.3.27試試
2.或者在使用./confingure編繹時，不要載入「--enable-maintainer-zts」參數，「--enable-maintainer-zts」參數的作用是啟用線程安全。

4. C#能不能像PHP一樣定義數組

你可以用ArrayList，裡面是object型，什麼類型都能放，然後按key來取值，key也是object型的。怎麼用都行。
當然也可以用HashTable，HashTable還是線性安全的。

具體的你可以看msdn中關於
System.Collections.ArrayList 和
System.Collections.Hashtable
的資料

5. 如何在php上安裝phalcon

下載phalcon 把phalcon.dll 放到相關目錄,一般是ext裡面 在php.ini中添加 extension=phalcon.dll 重啟環境

print_r(preg_grep('/^phalcon/i', get_declared_classes()));

6. php有1，2，3，4個數字，能組成多少個互不相同且無重復數字的三位數都是多少

能組成 A(4,3)=4*3*2=24 個互不相同且無重復數字的三位數

從小到大依次是:
123、124、132、134、142、143、
213、214、231、234、241、243、

7. bear hug infusion多少錢一瓶

bear hug infusion：CHF 42.00 加 8％的增值稅，加上運輸費用（1 CHF = 8.1408 CNY，所以總計342RMB加8％的增值稅，加上運輸費用）。
一般價位都介於30-50左右瑞士法郎，Birrecco比較貴需要108瑞士法郎。
具體的你可以看一下官網。

8. PHP系列沖洗液應用研究

（一）PHP系列沖洗液護壁機理

PHP是由聚丙烯醯胺（PAM）水解而成，是伸展的長鏈高分子化合物，具有多種非離 子吸附基團，如-CONH2等，可通過氫鍵吸附粘土表面，在岩層表面因多點吸附而形成薄 的吸附膜，不僅對水敏性地層可減輕泥漿濾液對地層的侵蝕作用，而且對破碎地層，也可 因阻止濾液滲入裂縫和多點吸附膜的保護而不易產生坍塌掉塊，故PHP沖洗液具有較好的 護壁性能。

當地層為構造破碎，裂隙發育，有掉塊現象，在PHP加入醇解度99％的聚乙烯醇（PVA），形成PHP＋PVA復配型無固相沖洗液，可取得較好護壁效果；當鑽遇礦層頂底板蝕 變帶含有綠泥石等水敏性地層時，可採用由PHP加腐殖酸鉀配製的無固相沖洗液。

（二）應用情況

採用PHP系列無固相沖洗液，在一般破碎地層鑽進，基本能夠解決孔壁穩定、潤滑 和防止WL鑽桿內壁結垢問題，取得較好的使用效果，與過去採用的細分散泥漿相比，平 均台月效率由原來的342m提高到430m，提高幅度達25.7％；孔內事故及停待率由原來的 31.25％下降為20.49％；優質孔率由原來的70％～80％提高到90％以上^［62］。
