How can PHP developers handle errors related to incompatible data types in SQL queries?

When handling errors related to incompatible data types in SQL queries, PHP developers can use parameterized queries to ensure that the data types match the expected values in the SQL statement. By binding parameters to the query, PHP will automatically handle any necessary type conversions, preventing errors related to incompatible data types. 

// Example of using parameterized queries to handle incompatible data types
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$id = 1; // Integer
$name = "John"; // String

$stmt = $pdo->prepare("SELECT * FROM users WHERE id = :id AND name = :name");
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->bindParam(':name', $name, PDO::PARAM_STR);
$stmt->execute();

// Fetch results
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
