What strategies can be employed to improve the accuracy of word matching in PHP scripts?

One strategy to improve the accuracy of word matching in PHP scripts is to use the `similar_text()` function, which calculates the similarity between two strings based on the number of matching characters. By comparing the similarity score of words, you can determine if they are closely related and improve the accuracy of word matching. 

$word1 = "apple";
$word2 = "apples";

similar_text($word1, $word2, $similarity);

if ($similarity > 80) {
    echo "Words are closely related.";
} else {
    echo "Words are not closely related.";
}
