What are some alternative methods to soundex for text filtering in PHP and MySQL?

Soundex is a phonetic algorithm used for indexing names by sound when performing searches. However, it may not always provide accurate results, especially for misspelled words or names. Alternative methods to soundex for text filtering in PHP and MySQL include using Levenshtein distance or metaphone algorithms to compare strings based on their similarity in spelling or pronunciation. 

// Using Levenshtein distance for text filtering in PHP and MySQL
$search_term = "example";
$sql = "SELECT * FROM table WHERE LEVENSHTEIN(column_name, '$search_term') <= 2";
$result = mysqli_query($conn, $sql);

// Using metaphone algorithm for text filtering in PHP and MySQL
$search_term = metaphone("example");
$sql = "SELECT * FROM table WHERE metaphone(column_name) = '$search_term'";
$result = mysqli_query($conn, $sql);
