Question

我的代码抛出以下错误：

警告：无法修改标头信息 - 已在第7行的/Users/johns/Desktop/Test/index.php中发送的标头（在/Users/johns/Desktop/Test/index.php:5中开始输出）< / p>

实际的代码问题似乎在这里：

<?php
if (isset($_GET["googlesearch"])) {
    header("Location: https://www.test.com/#!q=" . $_GET["googlesearch"] . "&page=0&refinements=%5B%5D&numerics_refinements=%7B%7D&index_name=%22_default_products%22");
    exit;
}
?>

我的完整页面代码是：

<!--

     here and the AMP Playground will render your document on the fly.

 <?php
if (isset($_GET["googlesearch"])) {
    header("Location: https://www.test.com/#!q=" . $_GET["googlesearch"] . "&page=0&refinements=%5B%5D&numerics_refinements=%7B%7D&index_name=%22_default_products%22");
    exit;
}
?>

                   placeholder="Search..."
                   name="googlesearch">
        </div>
        <input type="submit"
               value="OK"
               class="ampstart-btn caps">
    </form>

  </div>
</body>
</html>

我尝试将ob_start();放在多个地方，但没有运气。有人可以帮忙吗？

删除所有这些：

<!--
     This is the minimum valid AMP HTML document. Just type away
     here and the AMP Playground will render your document on the fly.
-->

从此之前：

<?php
if (isset($_GET["googlesearch"])) {
    header("Location: https://www.test.com/#!q=" . $_GET["googlesearch"] . "&page=0&refinements=%5B%5D&numerics_refinements=%7B%7D&index_name=%22_default_products%22");
    exit;
}
?>

<?php之前还有一个空格。如果在标题之前发送任何输出，则会给出错误。
