How can PHP developers dynamically pass parameters from a URL to retrieve specific data from external sources and process it within their code?

To dynamically pass parameters from a URL in PHP, developers can use the $_GET superglobal array to retrieve the parameters and then use them to fetch specific data from external sources. They can then process this data within their code by incorporating it into their logic or displaying it on their webpage. 

// Example of retrieving parameters from a URL and processing data

// Assuming the URL is http://example.com/data.php?id=123&category=books

$id = $_GET['id']; // Retrieve the 'id' parameter from the URL
$category = $_GET['category']; // Retrieve the 'category' parameter from the URL

// Use the parameters to fetch data from external sources (e.g., database, API)
// Process the data accordingly
// Display the processed data on the webpage
