How can the W3C recommendation to use & instead of & in URLs affect the validation of PHP code?

Using & instead of & in URLs can cause issues with PHP code validation because the & character is a special character in HTML and can lead to validation errors. To ensure proper validation, it's recommended to use & in URLs to represent the & character. 

$url = 'https://example.com/page.php?param1=value1&param2=value2';
echo $url;
