How can HTML entities like & impact PHP regex patterns and what are best practices for handling them?

HTML entities like & can impact PHP regex patterns by potentially causing unexpected behavior or errors if not properly handled. To address this issue, it's important to decode HTML entities before applying regex patterns to ensure accurate matching. 

$text = "This is an example text with & encoded entities.";
$text = html_entity_decode($text); // Decode HTML entities
$pattern = "/example/";
if (preg_match($pattern, $text)) {
    echo "Pattern found in text.";
} else {
    echo "Pattern not found in text.";
}
