Step By Step Guide On Registration Form In PHP With Validation :-

<?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;
}
?>

1. In this PHP code, several variables are defined as empty strings - $name, $email, $gender, $comment, and $website. During the form submission process, these variables will be filled with submitted data.
2. After checking the request's HTTP method, the script executes the request. A POST method retrieves the values from each form field and stores them in their respective variables if the method is different from a GET method. Data is sanitized and validated before being used using the test_input() function.
3. The test_input() function takes one parameter – $data. In the first step, the trim() function is used to remove any whitespace characters at the beginning or end of the string.
4. It then removes any backslashes with the stripslashes() function, in case the data was submitted with any malicious intent (like trying to inject JavaScript code or SQL statements).
5. Lastly, it converts any special characters to their HTML entity equivalents using the htmlspecialchars() function.
6. After the data has been sanitized, the function returns the cleaned up version of the data.
7. Overall, this code shows an example of how to securely handle form input data in PHP.
