How can PHP developers handle SQL syntax errors effectively?

When handling SQL syntax errors in PHP, developers can effectively use the try-catch block to catch any exceptions thrown by the database query execution. By wrapping the query execution code in a try block and catching any SQL syntax errors in the catch block, developers can handle these errors gracefully and provide appropriate error messages to the user.

try {
    // Database connection code
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    
    // SQL query with potential syntax error
    $stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
    $stmt->execute(['username' => $username]);
    
    // Fetch results
    $results = $stmt->fetchAll();
    
} catch (PDOException $e) {
    // Handle SQL syntax errors
    echo "SQL Syntax Error: " . $e->getMessage();
}
