Getting Started

Edit the src/DB.config.php file for your database configuration.

<?php

return [
    /**
     * Your database configuration. Modify accordingly.
     *
     * @see http://php.net/manual/en/pdo.construct.php
     */
    'DB_CONFIG' => [
        'host' => 'localhost',
        'port' => '',
        'dbname' => '',
        'username' => 'root',
        'password' => ''
    ],

    /**
     * Default PDO attributes. Modify accordingly.
     *
     * @see http://php.net/manual/en/pdo.setattribute.php
     */
    'PDO_ATTRIBUTES' => [
        PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
    ]
];

And that's it, you're good to go!

Usage

Namespacing

Make sure that this namespace is declared every time using the singleton DB class.

use PDO\DB;

Fetching

Fetch a single row in the result set

$singleRow = DB::i()->fetch('SELECT * FROM `users` WHERE `name` = :name', ['name' => 'Justin Beiber']);

Fetch a multiple rows in the result set

$multipleRows = DB::i()->fetchRows('SELECT * FROM `users`');

Extras

$multipleRows = DB::i()->fetchRows('SELECT * FROM `users`');

$rows = DB::i()->getRowCount(); // get the number of rows returned

$columns = DB::i()->getColumnCount(); // get the number of columns per row

var_dump($multipleRows);
var_dump($rows);
var_dump($columns);

$params = [
    ':address' => 'Urgello St., Cebu City, 6000, Cebu',
    ':name' => 'Karl Espiritu',
    ':email' => 'wiwa.espiritu@gmail.com'
];

DB::i()->exec("INSERT INTO `users`(`name`, `address`, `email`) VALUES (:name, :address, :email)", $params);

var_dump(DB::i()->getLastId()); // dumps the last inserted id

Update

$params = [
    ":name" => "John Mayer",
    ":email" => "mayer@somesite.com",
    ":id" => 3
];

$affectedRows = DB::i()->exec("UPDATE `users` SET name = :name, email = :email WHERE id = :id", $params);

var_dump($affectedRows); // dumps the number of affected rows
