1. 如何用php得到一个给定IP是属于哪个国家地区 - 技术问答

纯真IP数据库,能不能说明白点,要不你给我把代码看一下错在哪里.

2. PHP 位运算符

$h=16,$c=4,表达式16<<4的值为256，因为16（即二进制的00010000）向左移四位等于256（即二进制的100000000）

3. centOS 安装php5.3.28时报错

解决方法：
1.换成php版本5.3.27试试
2.或者在使用./confingure编绎时，不要加载“--enable-maintainer-zts”参数，“--enable-maintainer-zts”参数的作用是启用线程安全。

4. C#能不能像PHP一样定义数组

你可以用ArrayList，里面是object型，什么类型都能放，然后按key来取值，key也是object型的。怎么用都行。
当然也可以用HashTable，HashTable还是线性安全的。

具体的你可以看msdn中关于
System.Collections.ArrayList 和
System.Collections.Hashtable
的资料

5. 如何在php上安装phalcon

下载phalcon 把phalcon.dll 放到相关目录,一般是ext里面 在php.ini中添加 extension=phalcon.dll 重启环境

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

7. bear hug infusion多少钱一瓶

bear hug infusion：CHF 42.00 加 8％的增值税，加上运输费用（1 CHF = 8.1408 CNY，所以总计342RMB加8％的增值税，加上运输费用）。
一般价位都介于30-50左右瑞士法郎，Birrecco比较贵需要108瑞士法郎。
具体的你可以看一下官网。

8. PHP系列冲洗液应用研究

（一）PHP系列冲洗液护壁机理

PHP是由聚丙烯酰胺（PAM）水解而成，是伸展的长链高分子化合物，具有多种非离 子吸附基团，如-CONH2等，可通过氢键吸附粘土表面，在岩层表面因多点吸附而形成薄 的吸附膜，不仅对水敏性地层可减轻泥浆滤液对地层的侵蚀作用，而且对破碎地层，也可 因阻止滤液渗入裂缝和多点吸附膜的保护而不易产生坍塌掉块，故PHP冲洗液具有较好的 护壁性能。

当地层为构造破碎，裂隙发育，有掉块现象，在PHP加入醇解度99％的聚乙烯醇（PVA），形成PHP＋PVA复配型无固相冲洗液，可取得较好护壁效果；当钻遇矿层顶底板蚀 变带含有绿泥石等水敏性地层时，可采用由PHP加腐殖酸钾配制的无固相冲洗液。

（二）应用情况

采用PHP系列无固相冲洗液，在一般破碎地层钻进，基本能够解决孔壁稳定、润滑 和防止WL钻杆内壁结垢问题，取得较好的使用效果，与过去采用的细分散泥浆相比，平 均台月效率由原来的342m提高到430m，提高幅度达25.7％；孔内事故及停待率由原来的 31.25％下降为20.49％；优质孔率由原来的70％～80％提高到90％以上^［62］。
