Without a database, no practical PHP application could not exist. in php, we connect MySQL database by two most common ways: MySQLi(Improved MySQL) and PDO (PHP Data Objects) and along with OOP. in this post we must use PDO way to connecting the MySQL database server to php. PDO is a database access layer which gives a quick and reliable interface for accessing,managing databases in PHP and more stable extension. PDO will support 12 different database systems, while MySQLi will support only MySQL Database System. PDO & MySQLi will also support an API ‘Object Oriented’. IF you use another database system (database) something as like ORACLE, SQLite,IBM Db2, Cubrid, Microsoft SQL Server instead of My SQL Database in PHP, PHP Applications then PDO is Best Option of PHP. just change connection string and a few queries.it’s support Prepared statements.it’s also prevents SQL Injection Queries Attacks in PHP. in PHP 5.1 or Above Version  PDO_MySQL and PDO_SQLITE Driver is pre-default installed and enabled but only one extension default enabled ‘mysql . if you check what PDO Database System Drivers installed in PHP or your System then create a new PHP file and add the following code into it Example Download <?php print_r(PDO::getAvailableDrivers()); ?> Connecting to MySQL Database Basic Syntax : PHP-PDO DSN Connection String $pdo = new PDO(“mysql:host=hostname;dbname=database”, “username”, “password”); PDO accepts the given parameters for specifying the database source (known as DSN) which have contains the database servername or hostname  such as localhost or remote IP address ,database name and other optional parameters such as username and password that helps for connecting to database server.its creates a connection between php,php applications & database server.  to connect to mysql server, you must use the following data source name or above written syntax code example.the above written syntax code is some different because we use (OOP) classes and function in code.  $pdo = new PDO(“mysql:host=” . $this->db_host .”;dbname=” . $this->dbname, $this->db_user , $this->db_pass); Example Download <?php $db = new db(); class db { private $db_host = “localhost”; private $db_user = “root”; private $db_pass = “”; private $dbname = “test” ; public $error; protected function connect() { // $pdo = new PDO(“mysql:host=” . $this->db_host .”;dbname=” . $this->dbname, $this->db_user , $this->db_pass); $dsn = “mysql:host=” . $this->db_host .”;dbname=”.$this->dbname; $pdo = new PDO($dsn, $this->db_user , $this->db_pass); $pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC); return $pdo; } public function __construct() { $sql = “CREATE TABLE users ( name VARCHAR(111) NOT NULL , username VARCHAR(111) NOT NULL UNIQUE , password VARCHAR(111) NOT NULL ) ENGINE = InnoDB”; if($stmt = $this->connect()->query($sql)) { echo “Table created”; } else { echo “Table already created or Another Problem”; } } } ?> Check out this also:- You Can Call Police Without SIM Without Balance

People In Websites or Web Pages, Login System isn’t basic and not especially troublesome. So Today I Will Create The Full Login System . I will Create First Registration System then Login System in PHP using MySQL Database With XAMPP AND phpMyAdmin using Session system &  password_hash function method technique. With My Opinion Creating of Login System, First We Need a Specially Database in light of the fact that without database you probably won’t be completely use login system or page in sites or website pages, as in login system you do give subtleties, for example, username ,secret key or and so on , server or system can’t confirm the subtleties without database and its gets blunder if utilize brief area since system initially check subtleties whose you gave from database, so its essential. After That Good and Simple Code is needed.You Can Also Try Advanced Code But not utilize Complex Code. In PHP Programming, Many Codes are accessible of Login System whose that keeps running on various distinctive conditions and Platforms,Ways.So I Will Create  Login System in Easiest Way includes Registration System & Session System & Logout Function .  In Previous Login Tutorial Post i created the login system without encryption and stores data (username and password) in plain text in Database. But in this login tutorial post i use password_hash & password_verify encryption function method technique to store password into database . Here is Steps & Source Code of PHP login system First Open phpMyAdmin or MySQL by Localhost (Using XAMPP or WAMP). Create a Database Login & Table User. Second one is Create a Index.php & Config.php (Registration System) . Third is to Create a Login.php and Welcome.php & Session.php (Login System) . Building Registration System In this area we’ll construct a registration system that enables clients to make another record by rounding out a web structure. In any case, first we have to make a table in database that will hold all the client information. 1.Creating the Database Table Execute the following MySQL query to create the table user inside MySQL database. Example Download CREATE TABLE `user` (`id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT, `username` VARCHAR(111) NOT NULL UNIQUE ,`password` VARCHAR(255) NOT NULL , created_at DATETIME DEFAULT CURRENT_TIMESTAMP) ENGINE = InnoDB; 2.Create the Index.php Example Download <?php // Registration Page include(‘config.php’); if(isset($_SESSION[‘username’])){ header(“location: welcome.php”); // Redirecting To Welcome Page exit(); } if ($_SERVER[‘REQUEST_METHOD’] == “POST”){ if (!empty(trim($_POST[‘username’]))) { // Prepare a select statement $sql = “SELECT id FROM user WHERE username = ?”; if($stmt = mysqli_prepare($conn, $sql)){ // Set parameters $check_username = trim($_POST[‘username’]); // Bind variables to the prepared statement as parameters mysqli_stmt_bind_param($stmt, “s”, $check_username); // Attempt to execute the prepared statement if(mysqli_stmt_execute($stmt)){ /* store result */ mysqli_stmt_store_result($stmt); if(mysqli_stmt_num_rows($stmt) == 1){ $userpass_err = “This username is already taken.”; } elseif(strlen(trim($_POST[‘password’])) < 6 ) { $password_err = “Username OK ! Password has must alteast 6 Characters”; } else { $username = trim($_POST[“username”]); $password = trim($_POST[“password”]); $sql = “INSERT INTO user (username, password) VALUES (?, ?)”; $stmt = mysqli_prepare($conn, $sql); // Set these parameters $param_username = $username; $param_password = password_hash($password, PASSWORD_DEFAULT); mysqli_stmt_bind_param($stmt, “ss”, $param_username, $param_password); // Try to execute the query if (mysqli_stmt_execute($stmt)) { $suc = “Registered Sucessfully”; //Sucessful Message Pass Or Show header(‘refresh:5; url=login.php’); // Redirecting To Login Page } else { echo “something Wrong”; } mysqli_stmt_close($stmt); } } } } } mysqli_close($conn); ?< <html> <head> <link rel=”stylesheet” type=”text/css” href=”style.css”> </head> <body> <div> <h2>Welcome</h2> <form method=”post” action=”” enctype=”multipart/form-data”/> <input type=”text” name=”username” placeholder=”Username” required autofocus /> <input type=”password” name=”password” placeholder=”Password” required/> <br><span><?php echo $userpass_err;?> <?php echo $password_err; ?> <?php echo $suc; ?></span></br> <center><input type=”submit” value=”Create Account” name=”login_user”/></center></form> <div>Already Registered</div><a href=”login.php”><input type=”submit” value=”Click Here” name=”Click Here” /></a> </div> </body> </html> Firstly Script Checks the username is empty or not, if username is not empty then script will further move otherwise generate error. Second Checks the username is available in the database, if available then generate error message otherwise further moves to store username & password. Third one is checks the password is greater than 6 char otherwise populate error message. after this script or program store the username in plain text and password in encryption mode. last generate success message ‘registration successfully & move on to login page in 5 seconds. Layout of the Sign Up Form Page 3.Create the Config.php Example Download <?php session_start(); $suc = ”; $user_err = ”; $userpass_err = ”; $password_err = ”; $username = $password = “”; $check_username = $param_username = $param_password = ”; // Connection To Database My SQl & Main Root User $conn = mysqli_connect(“localhost”,”root”,””) or die (“could not connect”); // Selecting Database into MySQL Server (phpMyadmin) mysqli_select_db($conn,”login”) or die (“could not find database”); if($conn === false){ die(“ERROR: Could not connect. ” . mysqli_connect_error()); } ?> Declare Variables to Store Error and Success Message. Connecting to Mysql Database Server using mysqli_function & main root user otherwise generate error. Selecting to database into server. 4.Style.css Example Download @charset “utf-8″; /* CSS Document */ h2 { text-align: center; font-size:30px; display:block; text-transform: uppercase; margin: 0 auto; font-family: inherit; font-weight: 500; line-height: 1.1; color: inherit; } h1 { color: whitesmoke; font-weight: 500; } .h2 { text-align: center; font-size:16px; display:inline-block; text-transform: uppercase; font-family: inherit; top:1px; font-weight: 500; line-height: 1.1; color:black; } .box { background:white; border:2px solid hsla(0,11%,89%,1.00); border-radius:100px; } .col1{ color:peru; font-weight: 500; } .wrapper{ width:420px; height:460px; position:relative; margin: 10px 0px 0px 30%; background-color:#fff; text-align: center; border: 4px solid #B0C4DE; border-bottom: none; border-radius: 10px 10px 0px 10px; padding: 21px; } .img { background: url(images/back.jpg); } .col3 { background: url(images/04.jpg) center; } .form-signin{ display:block; width:400px; border: 1px solid rgba(0,0,0,0.1); padding: 5px; margin-left:3px; background:#6C0; color:#FFF; } .col { background-color:sandybrown; color: white; font-weight: 500; } .checkbox { margin-bottom: 28px; font-weight: normal; } input[type=”text”] { color: #0d0d0d; text-align: center; display: inline-block; font-size: 16px; width: 87%; height: 44px; margin: 20px 12px 10px 10px; border: 2px solid #f6f6f6; -webkit-transition: all 0.5s ease-in-out; -moz-transition: all 0.5s ease-in-out; -ms-transition: all 0.5s ease-in-out; -o-transition: all 0.5s ease-in-out; transition: all 0.5s ease-in-out; -webkit-border-radius: 5px 5px 5px 5px; border-radius: 2px 2px 2px 2px; } input[type=”password”] { color:

Make MYSQL DATABASE IN PHPMYADMIN AT THE LOCALHOST PHPMyAdmin is a control panel from where you can manage the database that you have created. Open your browser and type localhost/ then xampp page will open then click PHPMyAdmin after that PHPMyAdmin will open now then Click Database or New on Left Side phpMyadmin Page. Creating a Database at phpMyAdmin Name your database as per your needs. I am naming it ‘test’ database. To enter the name of the database in the text box then click create and your database will be made. Creating a Folder in Server ( XAMPP, Hosting Server, Wamp ) First Create a Folder in your according sever. in the event that you use xampp, at that point go to C:/xampp/htdocs/or on the off chance that you use wamp, at that point go to C:/wamp/www . on the off chance that you use web facilitating server as Cpanel, GoDaddy, big rock, etc, at that point your main directory or folder is public_html or www or htdocs or your domain directory . After that then create a folder and name it as per your need. I name it to ‘site’ . in folder create or save a PHP file and name it to ‘config.php’, ‘db.php’, ‘connect.php’, ‘database.php’ according to you need. I name it to index.php.Write the following code in your PHP file. Example Download <?php $error = “”; $success = “”; if($_SERVER[“REQUEST_METHOD”] == “POST”){ if(isset($_POST[‘connect’])){ $db_hostname = “localhost”; // Server Name Localhost $db_user = “root”; // Database Username or Host $db_pass = “”; // Password of Database Username or Host – $db = “test”; //Connecting to Database or Mysql Server $conn = mysqli_connect($db_hostname,$db_user,$db_pass) or die (“could not connect”); mysqli_select_db($conn,$db) or die (“could not find database”); if($conn) { $sql = “CREATE TABLE user ( name VARCHAR(111) NOT NULL , username VARCHAR(111) NOT NULL UNIQUE , password VARCHAR(111) NOT NULL ) ENGINE = InnoDB”; if(mysqli_query($conn,$sql)) { $success = “Table user is Created”; } else { $error = “Table Already Exist or Another Problem”; } } else { $error = “connection error”; } } } ?> <html> <head> <link rel=”stylesheet” type=”text/css” href=”style.css”> <head> <body> <div> <h2>SQL Connection Test</h2> <form method=”post” action=”” enctype=”multipart/form-data”> <center><input type=”submit” value=”Connect to MySQL Database” name=”connect”/></center> </form> <span style=”color:#6C0; font-size:25px;”><?php echo $success; ?></span> <span style=”color:#930; font-size:25px;”><?php echo $error; ?></span> </div> </body> </html> Example CSS Download @charset “utf-8”; /* CSS Document */ /* Style.css */ h2 { text-align: center; font-size:30px; display:block; text-transform: uppercase; margin: 0 auto; font-family: inherit; font-weight: 500; line-height: 1.1; color: inherit; } .h2 { text-align: center; font-size:16px; display:inline-block; text-transform: uppercase; font-family: inherit; top:1px; font-weight: 500; line-height: 1.1; color: inherit; } .wrapper { width:420px; height:400px; position:relative; margin: 60px 0px 0px 30%; background:url(back.jpg) ; text-align: center; border: 4px solid #B0C4DE; border-bottom: none; border-radius: 10px 10px 0px 10px; padding: 21px; } .form-signin { display:block; width:400px; border: 1px solid rgba(0,0,0,0.1); padding: 5px; margin-left:3px; border: 1px solid #B0C4DE; background:#333; color:#fff; } . .checkbox { margin-bottom: 28px; font-weight: normal;} input[type=button], input[type=submit], input[type=reset] { background-color: #56baed; border: none; color: white; display:inline-block; padding: 15px 80px; text-align: center; text-decoration: none; display: inline-block; text-transform: uppercase; font-size: 14px; -webkit-box-shadow: 0 10px 30px 0 rgba(95,186,233,0.4); box-shadow: 0 10px 30px 0 rgba(95,186,233,0.4); -webkit-border-radius: 5px 5px 5px 5px; border-radius: 5px 5px 5px 5px; margin: 140px 20px 40px 20px; -webkit-transition: all 0.3s ease-in-out; -moz-transition: all 0.3s ease-in-out; -ms-transition: all 0.3s ease-in-out; -o-transition: all 0.3s ease-in-out; transition: all 0.3s ease-in-out; } input[type=button]:hover, input[type=submit]:hover, input[type=reset]:hover { background-color: #39ace7; } input[type=button]:active, input[type=submit]:active, input[type=reset]:active { -moz-transform: scale(0.95); -webkit-transform: scale(0.95); -o-transform: scale(0.95); -ms-transform: scale(0.95); transform: scale(0.95); }
