Please do not use AI AND EXPLAIN EACH STEP, KEEP CODE AS SIMPLE AS POSSIBLE FOR BETTTER UNDERSTANDING: Activity $2$:

Build up your PHP skills by creating a simple "Contact Form" application. A contact form that captures a user's name, email, and message. Then, data is processed on the server side using PHP$.$ The form will include basic validation to ensure that all fields are filled out correctly.

Steps:

$1.$ Create the Form:

Open a new file and save it as contact.php in the www directory.

Create a form using the POST method with the following fields:

$-$ Name $($text input$)$

$-$ Email $($text input$)$

$-$ Message $($textarea$)$

Assign appropriate name attributes to each input field.

Include a submit button labeled "Send Message".

$2.$ Process the Form:

Start your PHP code by checking if the $\backslash$$$\_$POST array is not empty.

Declare variables for name, email, and message, and assign them the values from the form. Validate the inputs:

$-$ Check if all fields are filled.

$-$ Validate the email format using filter$\_$var$().$

Display a Success or Error Message:

$-$ If validation passes, display a success message and the submitted information.

$-$ If validation fails, display an appropriate error message.

Example PHP code:

$```$

If $($lenpty$($$$\_$POST$))($

$```$

$```$

$enail $=$ $ POST$[\text{'}$erail$\text{'}$l;

Sressage $-$ $$\_$l$$USI$[\text{'}$message$\text{'}]$;

$//$ Validation

if $($cmpty$($$name$)|$ cmpty$($$cmail$)||$ cmpty$($$messagc$))\{$

echo "All rields are required.";

$\}$ elsuif $(!$filler,$\_$var$($$$($$ertail, FILTER$\_$VALIDATE$\_$EMAIL$))\{$

ccho "Invalid email format.";

$|$ else I

$```$

$```$

$\}$

$]$

$```$

$3.$ Style the Form:

Create a CSS file called styles.css in the www directory.

Link this CSS file in the section of your contact.php$.$

Add some basic styles to make the form look nicer:

$-$ Center the form on the page.

$-$ Add padding and margin to inputs and the textarea.

$-$ Change the background color and text color for better readability.

$-$ Proper color for the validation messages
