What are some potential pitfalls when using wildcard selectors in PHP?

Using wildcard selectors in PHP can lead to unintended consequences, such as selecting more elements than intended or potentially selecting sensitive information. To avoid these pitfalls, it is important to be specific with wildcard selectors and double-check the elements being targeted. 

// Example of using a specific class selector instead of a wildcard selector
$elements = $doc->getElementsByTagName('div[class=myClass]');
foreach ($elements as $element) {
    // Do something with the selected elements
}
