Question

这是我第一次创建网站，我想在一个页面上注册和登录表单。每次我尝试注册它都会回显要登录的数据，基本上这个过程就会停止。如果我独立使用寄存器，它就可以正常工作。由于我使用的是bootstrap，我的整个代码都是一个大的（但注册/登录明显是分开的）。有没有两种方法指示PHP只在我工作的段中回显？

Answer 1

您可以像这样构建它：

<?php if ($someBool): ?>
   <form id="register">
      <!-- more html here -->
   </form>
<? else: ?>
   <form id="login">
      <!-- yet more html here -->
   </form>
<?php endif ?>

它是if的替代语法。见http://pl1.php.net/alternative_syntax

一个.php文件中有两个PHP回声。我可以隔离它们吗？
