How Do I Retrieve Input Field Values Using PHP\'s $_GET and $_POST?

Retrieving Input Field Values in PHP

When working with web forms, accessing the values entered in input fields is often necessary. PHP offers a straightforward solution for this through its $_POST and $_GET superglobals.

To retrieve the value of an input field, simply use the name attribute assigned to the tag. For instance, consider the following HTML code:

Using PHP, you can access this value as follows:

Using the $_GET Superglobal:

<?php echo $_GET['subject']; ?></p>
<p>This will output "Car Loan" in the browser when the form is submitted using the GET method.</p>
<p><strong>Using the $_POST Superglobal:</strong></p>
<pre class="brush:php;toolbar:false"><?php echo $_POST['subject']; ?>

Similarly, this will display "Car Loan" when the form is submitted using the POST method.

It's important to note that the choice between $_GET and $_POST depends on the nature of the data being collected and the desired behavior. GET is typically used for non-sensitive information and is visible in the URL, while POST is preferred for sensitive information and is not visible in the URL.
