In what ways can PHP developers optimize the process of querying and passing field values in PHP without relying heavily on WordPress functionalities?

PHP developers can optimize the process of querying and passing field values in PHP by utilizing PHP's built-in database functions, such as mysqli or PDO, to directly interact with the database. By writing custom SQL queries tailored to the specific data needed, developers can avoid the overhead of using WordPress functions for database operations. This approach allows for more efficient and flexible data retrieval and manipulation in PHP applications. 

// Establish a database connection using mysqli
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Perform a custom SQL query to retrieve field values
$sql = "SELECT field1, field2 FROM table WHERE condition = 'value'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Field1: " . $row["field1"]. " - Field2: " . $row["field2"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
