What is the purpose of passing parameters in a URL in PHP and how can they be effectively utilized?

Passing parameters in a URL in PHP allows for dynamic content to be displayed on a webpage based on user input or other conditions. This can be useful for creating search functionality, filtering data, or passing information between pages. Parameters can be accessed using the $_GET superglobal array in PHP, making it easy to retrieve and use the values in your code. 

// Example of passing parameters in a URL and accessing them in PHP

// URL: example.com/page.php?name=John&age=30

// Retrieve the parameters from the URL
$name = $_GET['name'];
$age = $_GET['age'];

// Output the values
echo "Name: " . $name . "<br>";
echo "Age: " . $age;
