How can you optimize your PHP code when dealing with JOIN queries to improve performance?

When dealing with JOIN queries in PHP, you can optimize your code by selecting only the necessary columns from the tables involved in the JOIN, using indexes on the columns being joined, and avoiding unnecessary JOINs. Additionally, you can use prepared statements to prevent SQL injection attacks and improve performance. 

// Example code snippet optimizing a JOIN query in PHP
$stmt = $pdo->prepare("SELECT table1.column1, table2.column2 
                       FROM table1 
                       JOIN table2 ON table1.id = table2.table1_id 
                       WHERE table1.column3 = :value");
$stmt->bindParam(':value', $value);
$stmt->execute();
$result = $stmt->fetchAll();
