Phiki: A Powerful PHP-Based Syntax Highlighter for Web and Terminal

Phiki is a syntax highlighter by Ryan Chandler written in PHP. It uses TextMate grammar file format and Visual Studio Code themes to generate syntax-highlighted code for the web and terminal. Here's an example of the API you can use to pass in a code snippet, language, and theme:

use Phiki\Phiki;
use Phiki\Grammar\Grammar;
use Phiki\Theme\Theme;

$phiki = new Phiki();

echo $phiki->codeToTerminal(
    <<<'PHP'
    use Illuminate\Support\Facades\Route;

    Route::get('/', function () {
        return view('welcome');
    });
    PHP,
    Grammar::Php,
    Theme::GithubDark,
);

echo "\n\n";

The results can be output to the terminal with styling matching the selected theme:

Using the codeToHtml() method, Phiki will return the HTML code (with inline styles) required to display the snippet in HTML. Phiki also supports line numbers, multi-theme support, and more:
