今天学习了一天的php和matlab

用php语言实现了html和php语言的交互

代码部分如下

<?php
$values='';
if(!empty($_POST))
{
    $num = $_POST['num'];
    $zhuanhuan = $_POST['zhuanhuan'];
    if($zhuanhuan == 2)
    {
        $values = decbin($num);
    }
    else if($zhuanhuan == 8)
    {
        $values = decoct($num);
    }
    else
    {
        $values = dechex($num);
    }
}
?>

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport"
          content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>转换进制</title>
</head>
<body>
<form action="php-7.php" method="post">
        十进制：<input type="text" name="num">
        请输入要转换的进制：<select name="zhuanhuan" id="">
            <option value="2">二进制</option>
            <option value="8">八进制</option>
            <option value="16">十六进制</option>
        </select><input type="submit" value="转换">
    <input type="text" name="" id="" value="<?php echo $values;?>"><br>

</form>
</body>
</html>

可以实现十进制转换成二进制，八进制，十六进制的页面
