What strategies can PHP developers employ to simplify and streamline complex SQL queries generated within PHP functions for improved code maintainability?

Complex SQL queries generated within PHP functions can make code difficult to maintain and debug. To simplify and streamline these queries, PHP developers can use query builder libraries like PDO or ORM frameworks like Eloquent. These tools provide a more structured way to write SQL queries, making them easier to read, maintain, and modify. 

// Example using PDO to simplify and streamline complex SQL queries
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Create a prepared statement
$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id");

// Bind parameters
$stmt->bindParam(':id', $userId, PDO::PARAM_INT);

// Execute the query
$stmt->execute();

// Fetch the results
$user = $stmt->fetch(PDO::FETCH_ASSOC);

// Close the connection
$pdo = null;
