我正在开发和在线代码判断项目。 我使用Php作为我的脚本语言。
在代码编译页面..用户编写代码的地方，我想对不同的编程语言使用语法高亮..
有没有办法做到这一点？
我尝试了SyntaxHighlighter - Alex Gorbatchev但无法使其正常工作
这是代码：
<?php
/*
* Solution submission page
*/
require_once('functions.php');
if(!loggedin())
header("Location: login.php");
else
include('header.php');
connectdb();
?>
<li><a href="index.php">Problems</a></li>
<li><a href="submissions.php">Submissions</a></li>
<li><a href="scoreboard.php">Scoreboard</a></li>
<li><a href="account.php">Account</a></li>
<li><a href="logout.php">Logout</a></li>
</ul>

正确格式化一大块代码以便以最佳方式显示它的“语法高亮显示”与语法高亮代码编辑器之间存在差异，允许用户输入将根据所选语言的语法着色的代码。
对于后者，我一直在使用CodeMirror，效果非常好。但是还有许多其他解决方案，relevant WikiPedia page包含广泛的列表和功能比较。
编辑：为了帮助您入门：首先阅读the manual，它显示了在代码中集成CodeMirror的不同可能方案。我认为在你的情况下，只使用一个简单的CodeMirror.fromTextArea()应该让你开始。 CodeMirror附带了大量示例like this one highlighting php。看看源代码，我在下面粘贴了相关部分：
<form><textarea id="code" name="code">
<?php
function hello($who) {
return "Hello " . $who;
}
?>
<p>The program says <?= hello("World") ?>.</p>
<script>
alert("And here is some JS code"); // also colored
</script>
</textarea></form>
<script>
var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
lineNumbers: true,
matchBrackets: true,
mode: "application/x-httpd-php",
indentUnit: 4,
indentWithTabs: true,
enterMode: "keep",
tabMode: "shift"
});
</script>
将CodeMirror.fromTextArea指向要突出显示的文本区域并（可选）设置选项以微调其行为，这很简单。
