What are some best practices for handling BB-Codes in PHP to ensure consistent and expected behavior in content rendering?

When handling BB-Codes in PHP, it is important to properly sanitize and parse the input to prevent any security vulnerabilities or unexpected behavior. One way to ensure consistent and expected behavior is to use a reliable BB-Code parser library that handles the parsing and rendering of the content. This helps to maintain consistency in rendering BB-Codes across different platforms and browsers. 

// Example using the HTML Purifier library to sanitize and parse BB-Codes
require_once 'path/to/HTMLPurifier.auto.php';

$config = HTMLPurifier_Config::createDefault();
$purifier = new HTMLPurifier($config);

$bbCode = "[b]Bold text[/b]";
$cleanHtml = $purifier->purify(bbcode_to_html($bbCode));

echo $cleanHtml;

function bbcode_to_html($bbCode) {
    // Implement your BB-Code to HTML conversion logic here
    // This is just a placeholder function, you can use a library or custom implementation
    return $bbCode;
}
