Are there any alternative libraries or tools besides highlight_string that can be used for syntax highlighting in PHP?

One alternative library for syntax highlighting in PHP is GeSHi (Generic Syntax Highlighter). GeSHi supports a wide range of languages and allows for customizable output. To use GeSHi for syntax highlighting in PHP, you can include the library in your project and use its functions to highlight code snippets. 

// Include the GeSHi library
require_once 'geshi.php';

// Create a new GeSHi object with the code and language
$geshi = new GeSHi($code, $language);

// Set the desired output format
$geshi->enable_line_numbers(GESHI_NORMAL_LINE_NUMBERS);

// Echo the highlighted code
echo $geshi->parse_code();
