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…在用户编写代码的地方，我想为不同的编程语言使用语法高亮。
有什么方法可以做到吗?
我试过SyntaxHighlighter - Alex Gorbatchev，但不能使它工作

语法高亮代码编辑器和语法高亮代码编辑器是有区别的，前者可以正确地格式化一段代码，使其以最佳方式显示，后者允许用户输入代码，并根据所选语言的语法为其着色。
对于后者，我一直在使用工作得很好的codemmirror。但还有许多其他的解决方案，相关的维基百科页面包含一个广泛的列表和功能比较。
编辑:让你开始:从阅读手册开始，它展示了在你的代码中集成codemmirror的不同可能场景。我认为在你的情况下，只要使用一个简单的CodeMirror.fromTextArea()就可以让你开始。CodeMirror提供了大量的例子，比如这个突出显示php的例子。查看源代码，我将相关部分粘贴在下面:
<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>
这是一个简单的指向CodeMirror.fromTextArea的文本区域，你想突出显示和(可选)设置选项，以微调其行为。
