好的,我第一次在这里提问。这在过去非常有帮助,但现在我迷路了。我试图通过一本书来了解 php 是如何工作的。所以我按照书中的说明进行了练习,结果如果不是应该的结果。
这是代码:
<div id="content">
<p>Here's a record of everything in the REQUEST array:</p>
<?php
foreach($_REQUEST as $value) {
echo "<p>" . $value . "</p>";
}
?>
</div>
<div id="footer"></div>
</body>
结果如下:
这是 REQUEST 数组中所有内容的记录:
" . $value . " "; } ?>
为什么不显示它应该显示的信息?谢谢。
好的,这是所有代码:
显示请求信息.php

> <div id="footer"></div> </body> </html>
这与名为“socialEntryForm.php”的文件一起使用
