What are the potential pitfalls of using a Top-Down approach in PHP project development?

One potential pitfall of using a Top-Down approach in PHP project development is that it may lead to a lack of flexibility and scalability. This approach involves starting with high-level modules and then breaking them down into smaller components, which can make it difficult to accommodate changes or additions later on. To address this issue, developers can consider using a more modular or bottom-up approach, where smaller components are built first and then integrated into larger modules.

// Example of a bottom-up approach in PHP project development

// Define a function to handle a specific task
function handleTask($data) {
    // Implement the functionality for the task
}

// Use the function in a higher-level module
$data = // some data
handleTask($data);
