How can PHP functions be utilized to optimize the workflow of updating database fields with conditional changes?

When updating database fields with conditional changes, PHP functions can be utilized to streamline the process by checking the conditions before executing the update query. This can help optimize the workflow and ensure that only the necessary changes are made to the database. 

// Example code to update database fields with conditional changes
$condition = true; // Example condition
$newValue = 'new value'; // New value to update the field with

if ($condition) {
    // Connect to database
    $conn = new mysqli($servername, $username, $password, $dbname);

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

    // Update query with condition
    $sql = "UPDATE table_name SET field_name = '$newValue' WHERE condition_field = 'condition_value'";

    if ($conn->query($sql) === TRUE) {
        echo "Record updated successfully";
    } else {
        echo "Error updating record: " . $conn->error;
    }

    // Close connection
    $conn->close();
}
