What are some best practices for linking words in PHP without affecting the case sensitivity?

When linking words in PHP without affecting case sensitivity, it is important to use the strtolower() function to convert all strings to lowercase before comparing them. This ensures that the comparison is not case-sensitive and allows for accurate linking of words regardless of their original case. 

$word1 = "Hello";
$word2 = "hello";

if(strtolower($word1) == strtolower($word2)) {
    echo "Words are linked!";
} else {
    echo "Words are not linked.";
}
