这篇文章主要介绍了PHP实现的简单三角形、矩形周长面积计算器分享,本文的实现相对较简单,同时提供了代码文件下载,需要的朋友可以参考下

运用PHP面向对象的知识设计一个图形计算器,,同时也运用到了抽象类知识,这个计算器可以计算三角形的周长和面积以及矩形的周长和面积。本图形计算器有4个页面:1.PHP图形计算器主页index.php;    2.形状的抽象类shape.class.php;    3三角形计算类triangle.class.php;    4.矩形计算类rect.class.php。

              矩形 ||             三角形         
          

       view();                   //第三步:用户是否提交了对应图形界面的表单                 if(isset($_POST['dosubmit'])) {                     //第四步:查看用户输出的数据是否正确, 失败则提示                     if($shape->yan($_POST)) {                         //计算图形的周长和面积                         echo $shape->name."的周长为:".$shape->zhou()."
";                         echo $shape->name."的面积为:".$shape->area()."
";                     }                 }               //如果用户没有单击链接, 则是默认访问这个主程序             }else {                 echo "请选择一个要计算的图形!
";               }           ?>     

形状的抽象类:

abstract class  Shape{     //形状的名称     public $name;       //形状的计算面积方法     abstract function area();       //形状的计算周长的方法     abstract function zhou();       //形状的图形表单界面     abstract function view();     //形状的验证方法     abstract function yan($arr);   }
