What are the potential implications of whitespace between DOM elements in PHP code on the layout of a webpage?

Whitespace between DOM elements in PHP code can affect the layout of a webpage by adding unintended spaces or line breaks. To solve this issue, you can use PHP's output buffering functions to capture the output and then strip any whitespace before sending it to the browser. 

<?php
ob_start();
?>
<!DOCTYPE html>
<html>
<head>
    <title>Whitespace Fix</title>
</head>
<body>
    <h1>Hello, World!</h1>
</body>
</html>
<?php
$output = ob_get_clean();
echo preg_replace('/\s+/', ' ', $output);
?>
