第一次来这里。我正在尝试使用 PHP/HTML 表单通过数据库进行查询，然后打印找到的结果的输出。问题是，我在最后一行代码（ish）上不断收到语法错误，它从后面的行</html>变为</body>标签。我知道它必须是一些我想念的简单的东西，但我已经认真地看了 4 个小时并且无法弄清楚。任何帮助将不胜感激。谢谢！

这是代码：

<html>
<head>
<title>Audit Activity Report</title>
</head>
<body>
<h4>Audit Activity Report</h4>

<?php
 if (!$_REQUEST['Submit']) { 
   html_form(); 
} else
{ 
 select_cd();  
 }
?>
function html_form()
{

<p>Please enter the fields you would like to run a report on:</p>

<form name="Audit Activity Report" method="post" action="<? echo $_SERVER['PHP_SELF']; ?>">
<p>
Employee BEMS: <input name="EmployeeBEMS" type="text" size="10" maxlength="10"> </p>
<p>Escort BEMS:
<input name="EscortBEMS" type="text" size="10" maxlength="10">
</p>
<p>Current Activity ID:
<input name="CurrentActivityID" type="text" size="20" maxlength="20">
</p>
<p>

</p>

<select name="EthicsTraining" id="EthicsTraining">

</select>
</p>
<p>
<label for="WorkAuthorization">Work Authorization:</label>
<select name="WorkAuthorization" id="WorkAuthorization">
<option>Yes</option>
<option>No</option>
</select>
</p>
<p>
<label for="Predicted Outcome">Predicted Outcome:</label>
<select name="Predicted Outcome" id="PredictedOutcome">
<option>Yes</option>
<option>No</option>
</select>
</p>
<p>
<input type="submit" name="Submit" value="View Report" /> </p>
<p>
<input type="reset" name="Clear" id="Clear" value="Clear" /> </p>
</form>

您的 php 开始和结束标记丢失 -

function html_form()
{

这样做——

<?php

function html_form()
{

HTML无法识别这些php方法，就像您之前在代码中所做的那样。

您需要将逻辑部分与视图分开，按照下面提到的方式进行操作（还有许多其他方法）

<?php

//PHP code chunks

?>
HTML Part
<?php

//Another PHP code chunks

?>
Again your HTML part

您需要确保所有 PHP 代码都在 PHP 标记内。您可以关闭 PHP 标记以编写原始 HTML。这是一个示例，来自您的代码：

<?php
 if (!$_REQUEST['Submit']) { 
   html_form(); 
} else
{ 
 select_cd();  
 }
?>
function html_form()
{

您需要更改它，因为它function html_form() {是 PHP，但它在 php 标签之外。试试这样：

<?php
 if (!$_REQUEST['Submit']) { 
   html_form(); 
} else
{ 
 select_cd();  
 }

function html_form()
{
?>

检查所有代码，确保所有 PHP 代码都在<?php ?>标签内。

为了将来参考，当您遇到 PHP 错误时，请务必告诉我们错误消息的内容，并准确找出错误发生的位置。这一点很重要。

您在文件末尾描述的错误是因为您最后一组 PHP 标记未关闭。按照我的解释检查您的代码，您将修复错误。修复错误消息后，还要查看您的输出页面。如果您在浏览器中看到任何看起来像 PHP 的东西，那么您错过了一些 PHP 打开/关闭标签。

我同意其他答案。您缺少打开和关闭 PHP 标记。

<?php ?>

如果您使用 Apache，另一个调试的好方法是您的 Apache error_log。帮了我几次。
