What are the differences between client-side and server-side capabilities in PHP for gathering user information?

When gathering user information in PHP, client-side capabilities refer to collecting data directly from the user's browser using JavaScript or HTML forms. Server-side capabilities involve processing and storing user information on the server using PHP scripts. To gather user information using client-side capabilities in PHP, you can use HTML forms to collect data and JavaScript to validate and manipulate the input before sending it to the server for processing. ```html <form action="process_form.php" method="post"> <label for="username">Username:</label> <input type="text" id="username" name="username"> <input type="submit" value="Submit"> </form> ``` In the PHP script "process_form.php", you can access the user input using the $_POST superglobal array:

$username = $_POST['username'];
echo "Hello, $username!";
