Features

• Simple [简单]
• Intuitive [直观]
• Independent [独立]
• Secure [安全]
• Based on PDO

Installation

Include both Base.php and Collection.php or install the composer package. See in detail index.php Examples in the document.

Examples

Connect to a database:

# the constructor takes the same parameters as the PDO constructor
$Base = new \klintlili\base\Base('mysql:host=localhost;dbname=example', 'username', 'password');

Work with records:

# read user 1
$Base->readItem('user', 1);
# update the username of user 1
$Base->updateItem('user', 1, ['username' => 'john.doe']);
# create a user
$Base->createItem('user', ['username' => 'jane.doe', 'email' => '[e-mail]']);
# delete user 1
$Base->deleteItem('user', 1);

Work with collections:

# read all users
$Base->find('user')->read();
# read the users that are marked as verified in a desc order
$Base->find('user')->whereEqual('is_verified', 1)->orderDesc('id')->read();
# read the user with the most reputation
$Base->find('user')->limit(1)->orderDesc('reputation')->readRecord();
# mark users 1 and 3 as verified
$Base->find('user')->whereIn('id', [1, 3])->update(['is_verified' => 1]);
# count the users that don't have a location
$Base->find('user')->whereNull('location')->count();
# plain sql conditions are also supported
$Base->find('user')->where('is_verified = ?', [1])->read();

Handle relationships:

# read the users that have a featured post
$Base->find('user')->has('post')->whereEqual('post.is_featured', 1)->read();
# read the posts of user 1
$Base->find('post')->belongsTo('user')->whereEqual('user.id', 1)->read();
# read the posts that are tagged "php"
$Base->find('post')->hasAndBelongsTo('tag')->whereEqual('tag.name', 'php')->read();
# unconventional FK names are also supported
$Base->find('user')->has('post', 'author_id')->whereEqual('user.id', 1)->read();

Execute queries:

# read all users
$Base->read('SELECT * FROM user');
# read user 1
$Base->readRecord('SELECT * FROM user WHERE id = ?', [1]);
# read the username of user 1
$Base->readField('SELECT username FROM user WHERE id = ?', [1]);
# read all usernames
$Base->readFields('SELECT username FROM user');
# update all users
$Base->update('UPDATE INTO user SET is_verified = ?', [1]);
