README
一个微小的PHP语法高亮器。使用 PhpToken 将PHP代码转换为PHP语言令牌，然后使用默认样式或您提供的自定义样式将这些令牌渲染为HTML。
用法
Vegetable.php
<?php // Great source of vitamins class Vegetable { public readonly string $edible; public readonly string $color; public function __construct(string $edible, string $color = "green") { $this->edible = $edible; $this->color = $color; } public function isEdible(): string { return $this->edible; } public function getColor(): string { return $this->color; } }
使用以下代码
$input = file_get_contents('Vegetable.php'); $html = new Highlighter()->render($input); echo $html;
生成以下HTML
<pre><code><span style="color: #3A97D4; font-weight: bold;"><?php<br></span><span style="color: #09814A; font-weight: bold;"><br></span><span style="color: #888; font-style: italic;">// Great source of vitamins</span><span style="color: #09814A;

PHP代码的每一部分都被渲染为带有内联样式的HTML <span> 标签。特殊字符，如引号，被转换为HTML实体，换行符被渲染为 <br> 标签。
在浏览器中渲染时，HTML将看起来像这样
自定义样式
高亮显示100%可自定义。
内部，Highlighter类使用令牌映射和样式映射。您可以将这两个映射传递给类的构造函数并覆盖默认值。您的令牌映射应包含PHP令牌代码（例如T_OPEN_TAG），并使用关键字分组。您的样式映射应将CSS样式映射到您为令牌映射选择的键词。
// If you enter the following token map $tokenMap = [ 'foobar' => [ T_STRING, // identifiers, e.g. keywords like parent and self, function names, class names and more T_CALLABLE, // any callable, ] ]; // Your style map has to contain styles for that keyword $styleMap = [ 'foobar' => 'color: #3A97D4; font-weight: bold;', ];
请参阅PHP文档以获取所有可能的解析令牌列表。
