HTML HREF中的PHP无法正常工作

Question

I am opening "email.php" inside of another php file. 我正在另一个PHP文件中打开“ email.php”。 "email.php" generates a random code to be nested into a hyperlink, but the randomly generated code is not being inserted. “ email.php”生成随机代码以嵌套到超链接中，但是不会插入随机生成的代码。 Instead, the literal string is being sent. 而是发送文字字符串。 The function randomCodeGenerator works and is in the util2.php file. 函数randomCodeGenerator可以使用，位于util2.php文件中。

<?php
   require_once "inc/util2.php";

   ?>

   <body>
      <?php
         $code = randomCodeGenerator(50);
         ?>

When I click the link sent to my email, the hyperlink looks like this: 当我单击发送到我的电子邮件的链接时，超链接如下所示：

http://corsair.cs.iupui.edu:21221/upload/lab2/validateLab2.php?a=%3C?phpecho%20$code;?%3E

Answer 1

try to alter the way you are adding the code, something like: 尝试更改添加代码的方式，例如：

$code = randomCodeGenerator(50);
$url = "http://corsair.cs.iupui.edu:21221/upload/lab2/validateLab2.php?a=".$code;

and finally ; 最后;

<a href='<?php echo $url;?'>

Answer 2

The file_get_contents just pulls the contents of the file and stores it to a variable. file_get_contents只是提取文件的内容并将其存储到变量中。 That bypasses the PHP processor, use the web server to process the file and then you will get the results. 这绕过了PHP处理器，使用Web服务器来处理文件，然后您将获得结果。 eg 例如

file_get_contents('http://yourscript.php');

instead of: 代替：

file_get_contents('/local/yourscript.php');
