README

A simple, modern, and lightweight PHP PDO wrapper for MySQL (and compatible databases). Built with type safety, PSR standards, and inspired by lincanbin/PHP-PDO-MySQL-Class.

Features

• Easy database connections with automatic retry
• Secure query binding (including IN (?) arrays support)
• Fluent methods for common operations (select, insert, update, delete)
• Transaction support
• Error handling with automatic reconnection on server timeout
• Simple logging for connection and query errors

Installation

You can install via Composer:

composer require victorvolpe/php-pdo-wrapper

Or simply include DB.php manually if you prefer not to use Composer.

Usage

1. Instantiate the Database

use VictorVolpe\PhpPdoWrapper\DB;

$db = new DB(
    dsn: 'mysql:host=localhost;dbname=testdb;charset=utf8mb4',
    user: 'your_username',
    pass: 'your_password'
);

2. Basic Query

$users = $db->query("SELECT * FROM users WHERE status = :status", [
    'status' => 'active'
]);

3. Fetch a Single Row

$user = $db->row("SELECT * FROM users WHERE id = :id", [
    'id' => 1
]);

4. Fetch a Single Column

$emails = $db->column("SELECT email FROM users WHERE status = :status", [
    'status' => 'active'
]);

5. Fetch a Single Value

$email = $db->single("SELECT email FROM users WHERE id = :id", [
    'id' => 1
]);

6. Insert a New Record

$newUserId = $db->insert('users', [
    'username' => 'newuser',
    'email' => 'newuser@example.com',
    'status' => 'active'
]);

7. Update Existing Records

$rowsAffected = $db->update('users', [
    'status' => 'inactive'
], "last_login < :date", [
    'date' => '2024-01-01'
]);

8. Delete Records

$rowsDeleted = $db->delete('users', "status = :status", [
    'status' => 'inactive'
]);

9. Transactions

$db->begin();

try {
    $db->query("UPDATE accounts SET balance = balance - :amount WHERE id = :id", [
        'amount' => 100,
        'id' => 1
    ]);

    $db->query("UPDATE accounts SET balance = balance + :amount WHERE id = :id", [
        'amount' => 100,
        'id' => 2
    ]);

    $db->commit();
} catch (Exception $e) {
    $db->rollback();
    throw $e;
}

Logging

If a connection error or query exception occurs, a log file will automatically be created in:

/logs/db-YYYY-MM-DD.log
