What are the potential pitfalls of using HTML entities in PHP for comparison operations?

Using HTML entities in PHP for comparison operations can lead to unexpected results because the entities are not directly comparable to their corresponding characters. To avoid this issue, it is recommended to decode the HTML entities before performing any comparison operations. 

$entity = '<';
$character = '<';

if(html_entity_decode($entity) === $character){
    echo "Entities match";
} else {
    echo "Entities do not match";
}
