What are the potential drawbacks of using explode() and a for loop to split words from a webpage in PHP?

Using explode() and a for loop to split words from a webpage in PHP may not handle all cases properly, especially if the webpage contains special characters or complex HTML structures. An alternative approach is to use a more robust HTML parsing library like DOMDocument to extract text content from the webpage. This will ensure more accurate extraction of words without issues related to special characters or HTML structure. 

$html = file_get_contents('https://example.com');
$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTML($html);
libxml_clear_errors();

$words = [];
foreach ($dom->getElementsByTagName('body')->item(0)->childNodes as $node) {
    if ($node instanceof DOMText) {
        $words = array_merge($words, preg_split('/\s+/', $node->nodeValue));
    }
}

print_r($words);
