The below code is used to create a MySQL database connection in PHP. When you insert form data into MySQL database, there you will include this file:
<?php
$servername='localhost';
$username='root';
$password='';
$dbname = "my_db";
$conn=mysqli_connect($servername,$username,$password,"$dbname");
if(!$conn){
die('Could not Connect MySql Server:' .mysql_error());
}
?>
Step 2 – Create a registration form and save data into MySQL database
In this step, you need to create an ajax search form and update the below code into your ajax search form.
<?php
require_once "db.php";
if(isset($_SESSION['user_id'])!="") {
header("Location: dashboard.php");
}
if (isset($_POST['signup'])) {
$name = mysqli_real_escape_string($conn, $_POST['name']);
$email = mysqli_real_escape_string($conn, $_POST['email']);
$mobile = mysqli_real_escape_string($conn, $_POST['mobile']);
$password = mysqli_real_escape_string($conn, $_POST['password']);
$cpassword = mysqli_real_escape_string($conn, $_POST['cpassword']);
if (!preg_match("/^[a-zA-Z ]+$/",$name)) {
$name_error = "Name must contain only alphabets and space";
}
if(!filter_var($email,FILTER_VALIDATE_EMAIL)) {
$email_error = "Please Enter Valid Email ID";
}
if(strlen($password) < 6) {
$password_error = "Password must be minimum of 6 characters";
}
if(strlen($mobile) < 10) {
$mobile_error = "Mobile number must be minimum of 10 characters";
}
if($password != $cpassword) {
$cpassword_error = "Password and Confirm Password doesn't match";
}
if (!$error) {
if(mysqli_query($conn, "INSERT INTO users(name, email, mobile_number ,password) VALUES('" . $name . "', '" . $email . "', '" . $mobile . "', '" . md5($password) . "')")) {
header("location: login.php");
exit();
} else {
echo "Error: " . $sql . "" . mysqli_error($conn);
}
}
mysqli_close($conn);
}
?>

$email_error = "Please Enter Valid Email ID";
}
if(strlen($password) < 6) {
$password_error = "Password must be minimum of 6 characters";
}
$result = mysqli_query($conn, "SELECT * FROM users WHERE email = '" . $email. "' and pass = '" . md5($password). "'");
if(!empty($result)){
if ($row = mysqli_fetch_array($result)) {
$_SESSION['user_id'] = $row['uid'];
$_SESSION['user_name'] = $row['name'];
$_SESSION['user_email'] = $row['email'];
