CRUD using PDO in PHP and MySQL

 In this tutorial I will show you how to create CRUD PDO application using PHP and MySQL

What is PDO?

   PDO = PHP Data Objects. This is a PHP extension that defines a consistent and lightweight interface for accessing databases.

    CRUD = Create/Read/Update/Delete. It means, any basic application that has ability to for creating, deleting, updating and reading the records in the database. Every database application like Inventory System, Accounting System, Point of Sale and other Business-related applications uses CRUD as basis of its database records manipulations.

Contents for PHP PDO CRUD

 Creating a database having a table

 Establishing the database connection

 Creating and Reading records

 Edit records

 Delete a record

Program Listing

connect.php

 <?php

$servername = "localhost";

$username = "root";

$password = "";

$dbname = "crud_pdo;

";

try {

    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);

    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    }

catch(PDOException $e)

    {

    echo "Connection failed: " . $e->getMessage();

    }

?>

Addition of Two Numbers in Java With Error Handling

Addition of Two Numbers in Java with Error Handling

 Machine Problem in Java

  Write a program using Java to ask the user to give two numbers and then it will compute the sum of the two numbers. If the user will give a character or a letter it will display an error message at asking again the user to give a number in order to compute the sum of the two numbers.
