I am implementing w3schools validating form in PHP, and why its showing PHP code with the form? although, it should not be. I don't know why this code is showing PHP code in localhost xammp. do you have any idea about this.

<!DOCTYPE HTML>  
<html>
<head>
</head>
<body>  

<?php
// define variables and set to empty values
$name = $email = $gender = $comment = $website = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {
  $name = test_input($_POST["name"]);
  $email = test_input($_POST["email"]);
  $website = test_input($_POST["website"]);
  $comment = test_input($_POST["comment"]);
  $gender = test_input($_POST["gender"]);
}

function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}
?>

JUST USE DOT. PHP Extension at the last that will resolve our issue.

You just had a space between < and php on line 45, also make sure the extension of your file is .php

try this

<!DOCTYPE HTML>  
<html>
<head>
</head>
<body>  

<?php
// define variables and set to empty values
$name = $email = $gender = $comment = $website = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {
  $name = test_input($_POST["name"]);
  $email = test_input($_POST["email"]);
  $website = test_input($_POST["website"]);
  $comment = test_input($_POST["comment"]);
  $gender = test_input($_POST["gender"]);
}

function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}
?>
