In this post, we are going to explain how to insert, delete, update tables on a database using php.

DataBase And Table:
CREATE DATABASE demo;
CREATE TABLE reg (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30) NOT NULL,
password VARCHAR(30) NOT NULL,
address VARCHAR(30) NOT NULL,
email VARCHAR(50),
fathername VARCHAR(30) NOT NULL,
mothername VARCHAR(30) NOT NULL,
country VARCHAR(50),
state VARCHAR(30) NOT NULL,
city VARCHAR(50),
photo VARCHAR(50))
INSERT
$query=mysql_connect("localhost","root","");
mysql_select_db("demo",$query);
if(isset($_POST['send']))
{
$name=$_POST['name'];
$password=$_POST['password'];
$address=$_POST['address'];
$email=$_POST['email'];
$fathername=$_POST['fathername'];
$mothername=$_POST['mothername'];
$country=$_POST['country'];
$state=$_POST['state'];
$city=$_POST['city'];
$photo=$_FILES["file"]["name"];
$tempphoto=$_FILES["file"]["tmp_name"];
$mode = 0777; 
 $target_dir = "upload/";
 if(!is_dir($target_dir))
 {
 mkdir($target_dir,$mode, true); 
 }
 move_uploaded_file($_FILES['file']['tmp_name'],$upload);
$in=mysql_query("insert into reg values('', '$name', '$password', '$address', '$email', '$fathername', '$mothername', '$country', '$state', '$city','$photo')");
}
