PHP Exercises : Create a HTML form and accept the user name and display the name

PHP : Exercise-4 with Solution

Create a simple HTML form and accept the user name and display the name through PHP echo statement.

HTML form: A webform or HTML form on a web page allows a user to enter data that is sent to a server for processing. Forms can resemble paper or database forms because web users fill out the forms using checkboxes, radio buttons, or text fields. For example, forms can be used to enter railway or credit card data to purchase a product, or can be used to retrieve search results from a search engine.

Sample Solution: -

PHP Code:

<!DOCTYPE html>
<html>
<head>
   <title></title>
   <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
   </head>
   <body>
   <form method='POST'>
   <h2>Please input your name:</h2>
 <input type="text" name="name">
 <input type="submit" value="Submit Name">
 </form>
<?php
//Retrieve name from query string and store to a local variable
$name = $_POST['name'];
echo "<h3> Hello $name </h3>";
?>
</body>
</html>

PHP: Tips of the Day

Why shouldn't I use mysql_* functions in PHP?

The MySQL extension:

  • Is not under active development
  • Is officially deprecated as of PHP 5.5 (released June 2013).
  • Has been removed entirely as of PHP 7.0 (released December 2015)
  • This means that as of 31 Dec 2018 it does not exist in any supported version of PHP. If you are using a version of PHP which supports it, you are using a version which doesn't get security problems fixed.
  • Lacks an OO interface
  • Doesn't support:
    • Non-blocking, asynchronous queries
    • Prepared statements or parameterized queries
    • Stored procedures
    • Multiple Statements
    • Transactions
    • The "new" password authentication method (on by default in MySQL 5.6; required in 5.7)
    • Any of the new functionality in MySQL 5.1 or later

Since it is deprecated, using it makes your code less future proof.

Lack of support for prepared statements is particularly important as they provide a clearer, less error-prone method of escaping and quoting external data than manually escaping it with a separate function call.
