PHP条件运算符示例

试试下面的例子就明白了条件运算符。复制并粘贴到test.php文件，将下面的PHP程序保存它在PHP服务器的文档根目录，使用浏览器浏览。

<html>
<head><title>Arithmetical Operators</title><head>
<body>
<?php
    $a = 10;
    $b = 20;
    
    /* If condition is true then assign a to result otheriwse b */
    $result = ($a > $b ) ? $a :$b;
    echo "TEST1 : Value of result is $result<br/>";
    /* If condition is true then assign a to result otheriwse b */
    $result = ($a < $b ) ? $a :$b;
    echo "TEST2 : Value of result is $result<br/>";
?>
</body>
</html>

这将产生以下结果

TEST1 : Value of result is 20
TEST2 : Value of result is 10
