我正在尝试使用php创建在线评论系统。这是我的php页面，里面有HTML。但是，它没有按预期执行，HTML元素被渲染，而php在执行期间作为垃圾返回。我错过了什么吗？我是否使用.htaccess文件告诉编译器将其作为纯文件执行？
这是我的代码：
<?php
if (version_compare(phpversion(), "5.3.0", ">=") == 1)
error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);
else
error_reporting(E_ALL & ~E_NOTICE);
require_once('classes/CMySQL.php');
$sCode = '';
$iItemId = (int)$_GET['id'];
if ($iItemId) { // View item output
$aItemInfo = $GLOBALS['MySQL']->getRow("SELECT * FROM `s163_items` WHERE `id` = '{$iItemId}'"); // getting info about item from database
$sCode .= '<h1>'.$aItemInfo['title'].'</h1>';
$sCode .= '<h3>'.date('F j, Y', $aItemInfo['when']).'</h3>';
$sCode .= '<h2>Description:</h2>';
$sCode .= '<h3>'.$aItemInfo['description'].'</h3>';
$sCode .= '<h3><a href="'.$_SERVER['PHP_SELF'].'">back</a></h3>';
$sComments = '';
$aComments = $GLOBALS['MySQL']->getAll("SELECT * FROM `s163_items_cmts` WHERE `c_item_id` = '{$iItemId}' ORDER BY `c_when` DESC LIMIT 5");

请检查var selectedprocesslist = processlist.Where(o => Convert.ToInt16(o.Name.Split('-')[1]) <= Convert.ToInt16(("process-4").Split('-')[1])).ToList();
开始标记。缺少<?php。
