极客教程PHP 算术运算符示例
尝试以下示例来理解所有的算术运算符。将下面的PHP程序复制并粘贴到test.php文件中，并将其保存在您的PHP服务器的文档根目录中，并使用任何浏览器浏览它。
<html>
<head>
<title>Arithmetical Operators</title>
</head>
<body>
<?php
a = 42;b = 20;
c =a + b;
echo "Addtion Operation Result:c <br/>";
c =a - b;
echo "Substraction Operation Result:c <br/>";
c =a * b;
echo "Multiplication Operation Result:c <br/>";
c =a / b;
echo "Division Operation Result:c <br/>";
c =a % b;
echo "Modulus Operation Result:c <br/>";
c =a++;
echo "Increment Operation Result: c <br/>";c = a--; echo "Decrement Operation Result:c <br/>";
?>
</body>
</html>
这将产生以下结果-
Addtion Operation Result: 62
Substraction Operation Result: 22
Multiplication Operation Result: 840
Division Operation Result: 2.1
Modulus Operation Result: 2
Increment Operation Result: 42
Decrement Operation Result: 43
