What resources or documentation can PHP developers refer to for optimizing MySQL queries in PHP applications?

PHP developers can refer to the MySQL documentation for optimizing queries in PHP applications. Additionally, they can use tools like MySQL EXPLAIN to analyze query execution plans and identify potential bottlenecks. By optimizing queries, developers can improve the performance of their PHP applications and reduce load on the database server. 

// Example of optimizing a MySQL query in PHP using MySQL EXPLAIN

$query = "SELECT * FROM users WHERE status = 'active'";
$result = mysqli_query($conn, "EXPLAIN " . $query);

while ($row = mysqli_fetch_assoc($result)) {
    print_r($row);
}

// Analyze the output of EXPLAIN to identify potential optimizations
