How can PHP developers optimize the performance of database queries that involve pattern matching in PHP?

When performing database queries that involve pattern matching in PHP, developers can optimize performance by using indexes on the columns being searched. Indexes can significantly speed up query execution by allowing the database engine to quickly locate the relevant rows. Additionally, developers can consider using full-text search capabilities provided by the database system for more complex pattern matching requirements. 

// Example of optimizing database query with pattern matching using indexes

// Assuming we have a table named 'users' with a column 'username' that we want to search for a specific pattern

// Create an index on the 'username' column for faster search
CREATE INDEX idx_username ON users(username);

// Perform the optimized query with pattern matching
$searchPattern = 'john%'; // Search for usernames starting with 'john'
$query = "SELECT * FROM users WHERE username LIKE :pattern";
$stmt = $pdo->prepare($query);
$stmt->execute(['pattern' => $searchPattern]);
$results = $stmt->fetchAll();
