Pixie – A Database Query Builder for PHP

It took me few weeks to build Pixie, a lightweight, expressive, framework agnostic query builder for PHP, it can also be referred as a Database Abstraction Layer. Pixie supports MySQL, SQLite and PostgreSQL and it takes care of query sanitization, table prefixing and many other things with a unified API. At least PHP 5.3 is required.

It has some advanced features like:

  • Query Events
  • Nested Criteria
  • Sub Queries
  • Nested Queries
  • Multiple Database Connections.

Check out the installation instructions and documentation on GitHub.

Example

// Make sure you have Composer's autoload file included
require 'vendor/autoload.php';

// Create a connection, once only.
$config = array(
            'driver'    => 'mysql', // Db driver
            'host'      => 'localhost',
            'database'  => 'your-database',
            'username'  => 'root',
            'password'  => 'your-password',
            'charset'   => 'utf8', // Optional
            'collation' => 'utf8_unicode_ci', // Optional
            'prefix'    => 'cb_', // Table prefix, optional
        );

new \Pixie\Connection('mysql', $config, 'QB');

Simple Query:

The query below returns the row where id = 3, null if no rows.

$row = QB::table('my_table')->find(3);

Full Queries:

$query = QB::table('my_table')->where('name', '=', 'Sana');

// Get result
$query->get();

Query Events:

After the code below, every time a select query occurs on users table, it will add this where criteria, so banned users don’t get access.

QB::registerEvent('before-select', 'users', function($qb)
{
    $qb->where('status', '!=', 'banned');
});

There are many advanced features which are documented on GitHub project page. Sold? Lets install.
