How can PHP be used to handle cases where the difference between two strings is not as straightforward as in the given example?

When the difference between two strings is not as straightforward as in the given example, we can use PHP functions like `similar_text()` or `levenshtein()` to calculate the similarity or distance between the strings. These functions provide a more nuanced approach to comparing strings and can be useful in cases where a simple character-by-character difference may not be sufficient. 

$string1 = "apple";
$string2 = "aple";
similar_text($string1, $string2, $percent);
echo "Similarity: $percent%";

$distance = levenshtein($string1, $string2);
echo "Levenshtein distance: $distance";
