What are some potential pitfalls when using soundex() for handling typos in a database?

One potential pitfall when using soundex() for handling typos in a database is that it may not always accurately capture all variations of a word due to its simplistic algorithm. To improve accuracy, you can consider using more advanced phonetic matching algorithms such as Metaphone or Double Metaphone. 

// Example using Metaphone for more accurate phonetic matching
$word = "example";
$metaphone = metaphone($word);

// Query database for similar sounding words using Metaphone
$query = "SELECT * FROM words WHERE metaphone = '$metaphone'";
$result = mysqli_query($conn, $query);

// Process results
while($row = mysqli_fetch_assoc($result)) {
    echo $row['word'] . "<br>";
}
