GeekLab\GLPDO2

Easy to use PDO Wrapper for PHP >= 8.1

Latest

2022-11-25 (4.0.9)

  • Style fixes.

Features

  • Bind value by the correct type. E.g. Don't bind as a string where an integer bind should be.
  • Bindings are injected, so you can create your own!
  • Help prevent injections.
  • PSR1/2/4 Compliant.

Installation

composer require geeklab/glpdo2

Todo

  • More tests, since we can test at many levels and implementations.
  • Better schema for testing.
  • Better docs.
  • More of a real wold example.
  • Reduce the complexity?

Basic Usage (Quick-N-Dirty)

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');

define('DS', DIRECTORY_SEPARATOR);
require_once '..' . DS . '..' . DS . 'vendor' . DS . 'autoload.php';

$dbConn    = new PDO('mysql:host=localhost;dbname=playground', 'root', '', [PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION]);
$db        = new \GeekLab\GLPDO2\GLPDO2($dbConn);
$Statement = new \GeekLab\GLPDO2\Statement(GLPDO2\Bindings\MySQL\MySQLBindingFactory::build());
$start     = 0;
$limit     = 5;

$Statement->sql('SELECT *')
          ->sql('FROM (')
          ->sql('          SELECT *')
          ->sql('          FROM   `mock_data`')
          ->sql('          LIMIT  ?, ?')->bInt($start)->bInt($limit)
          ->sql('     ) SUBQ')
          ->sql('ORDER BY `id` DESC;');

// Show computedSQL statement
print_r($Statement->getComputed());

$res = $db->selectRows($Statement);

print_r($res);
