How can the issue of case sensitivity in PHP be addressed by converting comparison parameters to lowercase before comparison?

Case sensitivity in PHP can be addressed by converting comparison parameters to lowercase before comparison. This ensures that the comparison is done in a case-insensitive manner, allowing for more accurate matching of strings regardless of their case.

$string1 = "Hello";
$string2 = "hello";

if (strtolower($string1) === strtolower($string2)) {
    echo "Strings are equal regardless of case.";
} else {
    echo "Strings are not equal.";
}
