What are common challenges faced when integrating a syntax highlighter for PHP code in a forum setting?

Common challenges when integrating a syntax highlighter for PHP code in a forum setting include ensuring compatibility with the forum software, handling code formatting inconsistencies, and preventing code injection vulnerabilities. One way to address these challenges is to use a trusted syntax highlighting library or plugin that is specifically designed for PHP code highlighting. 

// Example code snippet using the GeSHi library for PHP syntax highlighting
require_once 'geshi/geshi.php';

$phpCode = '<?php echo "Hello, World!"; ?>';

$geshi = new GeSHi($phpCode, 'php');
echo $geshi->parse_code();
