Question

我有一个process.php文件用于处理评论/消息表单。如果在处理过程中出现错误，则会回显错误的表单内容，并将其显示为名为process.php的网页，以便进行更正和重新提交。

问题是我需要回显的内容包含各种<?php include("xxxx.php");?>元素，以便它与我网站的其余部分匹配。但这似乎使页面翻倒（显示没有内容的空白页）。我被告知我应该在回显的内容中使用include("xxxx.php");或echo file_get_contents("xxxx.php");，但都不会显示预期的内容。

非常感谢对这些问题的任何帮助。

你只是像往常一样使用CSS ......

<?php
    // index.php
?>
<!doctype html>
<html>
    <head>
        <style type="text/css">
            .myClass {
                color: #f00;
            }
        </style>
    </head>
    <body>
        <?php
            include('myFile.php');
        ?>
    </body>
</html>

<?php
    // included myFile.php
    echo '<p class="myClass">Echoed content!</p>';

如果你最后得到一个没有内容的空白页面，那么你的PHP可能会有错误。确保启用错误报告，您将能够看到出现了什么问题。

如何在'echo'内容中使用php'include'功能？
