Create A Login Form Validation Using PHP And WAMP / XAMPP

Introduction

 
WAMP stands for Windows, Apache, MySQL, and anyone of PHP, Perl, or Python. WAMP server is a local webserver for running the scripting language (PHP, Perl) and this is open source. XAMPP stands for Cross-Platform (X), Apache (A), Maria DB (M), PHP (P), and Perl (P). It is developed by Apache Friends. It includes Apache and MySQL, FileZilla, Mercury, Tomcat, and Maria DB.
 
Here, I am going to show how to create a login form validation, using PHP and XAMPP.
 
Requirements
  • XAMPP/WAMP Server.
  • Brackets (IDE).
  • Little HTML, CSS, and PHP knowledge.
Steps given below are required to be followed
 
Follow the steps to create a login form validation, using PHP and XAMPP. I have included the source code, which is given below.
 
Step 1
 
Open the XAMPP Control Panel. Start Apache and MySQL Server.
 
PHP
 
Step 2
 
Open your browser and then type http:// localhost or http://127.0.0.1. After you see the XAMPP community page, make sure, if your Server is running or not.
 
PHP
 
Step 3
 
Open XAMPP Control Panel, followed by clicking MySQL admin. Now, create the database for the login validation form.
 
PHP
 
Step 4
 
To create the new database, click New.
 
PHP
 
Step 5
 
Put the database name, which you want. Here, the database name is user-registration, followed by clicking create.
 
PHP
 
Step 6
 
Go to the SQL query tab, copy and paste the query given below. Click go. Afterward, your table (my table name: person) is created successfully.
 
SQL query 
  1. CREATE TABLE IF NOT EXISTS `login` (  
  2.   `username` varchar(200) NOT NULL,  
  3.   `password` varchar(200) NOT NULL,  
  4.   PRIMARY KEY (`username`)  
  5. ) ENGINE=InnoDB DEFAULT CHARSET=latin1;   
PHP
 
 
Step 7
 
Put your Webpage files into the destination folder. Default folder is c:/xampp/htdocs.
 
PHP
 
Step 8
 
Open the bracket(IDE) and create the login.php file. Copy the code given below and paste into login.php 
  1. <!doctype html>  
  2. <html>  
  3. <head>

  49. ?>  
PHP
 
Now, you need to click the logout.
 
Output
 
Now, check the database to check, whether our data was stored or not.
 
PHP
 
Here, we have successfully created a login form validation. Using PHP and WAMP/XAMPP, and we created and executed it. I will continue my next article to give you in-depth knowledge about XAMPP, FileZilla, and GitHub lessons.
