PHP有很多值得学习的地方,这里我们主要介绍PHP二维数组赋值,下面我们先简单的总结一下PHP吧。对于普通电脑爱好者来说,PHP或许是一个陌生的名字。比较关注网络的朋友,特别是关注网站建设技术的朋友,可能听说过PHP。PHP是一种为动态创建HTML内容而设计的简单但功能强大的编程语言。

PHP本身是一种简单而强大的语言。PHP语言拥有核心特性如强大的字符串和数组处理能力,同时极大的改进了对面向对象编程的支持(PHP5以上版本)。通过使用标准的和可选的扩展模块,PHP应用程序可以连接MySQL或Oracle等十几种数据库、绘图、创建PDF文件和创建解析XML文件。你也可以使用C语言来写自己的PHP扩展模块。例如,在已存在的代码库中提供一个PHP的接口函数。你也可以在Windows下运行PHP,使用COM控制其它诸如Word和Excel的Windows应用程序,或者使用ODBC来连接数据库。以上就简短的对PHP的介绍,下面我们来看看PHP二维数组赋值的相关知识。

在ASP中

1

<ol class="dp-xml"><li class="alt"><span><span>dim NamAre() //定义数组 </span></span></li></ol>

Copy after login

通过SQL语句查询得到记录数为total.

1

<ol class="dp-xml"><li class="alt"><span><span>redim NamAre(total,2) //重新定义数组,其中total为查询得到的记录数 </span></span></li></ol>

Copy after login

通过while 循环赋值

1

2

3

4

<ol class="dp-xml">

<li class="alt"><span><span>NamAre(i,1)=rolename  </span></span></li>

<li class=""><span>NamAre(i,2)=Area </span></li>

</ol>

Copy after login

但这在里如何实现PHP二维数组赋值?在PHP里,我定义二维数组:

1

2

3

4

<ol class="dp-xml">

<li class="alt"><span><span>$</span><span class="attribute"><font color="#ff0000">data_array</font></span><span>=array($total,2);//其中$datarows为查询得到的记录数  </span></span></li>

<li class=""><span>$data_array[$i][2]=$Area;//提示错误:Cannot use a scalar value as an array </span></li>

</ol>

Copy after login

具体的循环如下:SQL语句.......

1

2

3

4

5

6

7

8

9

10

11

12

13

14

15

16

<ol class="dp-xml">

<li class="alt"><span><span>$</span><span class="attribute">i</span><span>=</span><span class="attribute-value">0</span><span>;  </span></span></li>

<li class="">

<span>while($</span><span class="attribute">result</span><span>=$db-</span><span class="tag">></span><span>fetch_array($query))  </span>

</li>

<li class="alt"><span>{  </span></li>

<li class="">

<span>$</span><span class="attribute">Area</span><span>=$result["Area"];  </span>

</li>

<li class="alt"><span>$data_array[$i][2]=$Area//出错!  </span></li>

<li class="">

<span>$</span><span class="attribute">i</span><span>=$i+1;  </span>

</li>

<li class="alt"><span>   </span></li>

<li class=""><span>}  </span></li>

</ol>
