How can the choice of database engine (e.g., InnoDB vs. MyISAM) affect the syntax and execution of SQL queries in PHP scripts?

The choice of database engine can affect the syntax and execution of SQL queries in PHP scripts because different engines support different features and have different performance characteristics. For example, InnoDB supports transactions and foreign keys while MyISAM does not. To ensure compatibility across different database engines, it is recommended to use standard SQL syntax and avoid engine-specific features. 

// Example of using standard SQL syntax to ensure compatibility across different database engines
$sql = "SELECT * FROM table_name WHERE column_name = :value";

// Prepare and execute the query using PDO
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':value', $value);
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll();
