What are the advantages and disadvantages of using LIKE 'A%' in SQL queries compared to other methods for filtering data in PHP?

When using LIKE 'A%' in SQL queries, it allows for filtering data based on a specific pattern, such as words starting with the letter 'A'. This can be useful for searching and retrieving specific data. However, using LIKE 'A%' can also be less efficient compared to other methods, as it may not utilize indexes effectively and could result in slower query performance. 

// Using a different method for filtering data in PHP
$searchTerm = 'A';
$sql = "SELECT * FROM table_name WHERE column_name LIKE :searchTerm";
$stmt = $pdo->prepare($sql);
$stmt->execute(['searchTerm' => $searchTerm . '%']);
$results = $stmt->fetchAll();
