Question

在下面的代码中，我试图单击时分别更改每个图像。我已经通过在每个图像上使用超链接来开始此操作，单击该链接时应更改为第二个图像，其数组为['name'] ['1']。但是，当前代码仅会针对图像['name'] ['0']循环，因为我无法弄清楚如何测试是否已单击图像。

我已经发现，如果我能够以某种方式将$ _GET值用于每个数组的变量，我可以测试每个变量是['0']还是['1']，然后为循环创建一个函数以将每个数字设置为0或1，具体取决于是否单击了图像。

<head>
    <style>
        .floatleft {
            float: left;
        }
        .floatright {
            float: right;
        }
        div {
            width: 500px;
        }
    </style>
</head>

<body>
    <center>
        <?php

</body>

如果点击图片，我该如何做？可以像我说的那样用$ _GET做到吗？

来自多维数组的$ _GET值？
