Introduction

SimplePDOWrapper's purpose is to help you handle simple database actions with a reduced amount of code as well as writting less-messy code following a simple structure.

You can:

• Save
• Update
• Delete (with conditions)
• Delete all (without conditions)
• Find one
• Find all
• Set database (switch on the fly)
• Error handling through public var @errors

Dependencies

• PHP PDO

PHP Version

This class is compatible with PHP 5.0 and above due to the PHP PDO dependency.

Installing

Add this library to your Composer configuration. In composer.json:

  "require": {
    "adrian0350/simple-pdo-wrapper": "1.*"
  }

Or

If you're using bash.

$ composer require adrian0350/simple-pdo-wrapper

Usage

For usage just call the methods from your SimplePDOWrapper instance object.

<?php

require_once dirname(dirname(__FILE__)).'/src/SimplePDOWrapper.php';

$conf = array(
	'database' => 'your_db_name',
	'username' => 'root',
	'password' => 'toor',
	'host' => 'localhost'
);
$SimplePDOWrapper = new SimplePDOWrapper($conf);

Options param

Options are available with

• conditions
  • >
  • <
  • >=
  • <=
  • !=
  • LIKE
  • And more complex clauses: (UNIX_TIMESTAMP(calldate) + callduration) >=
• limit
• fields
• order

// For now conditions only has basic clause.
$options = array(
	'conditions' => array(
			'username' => 'john.doe@email.com'
		),
	'limit' => 10,
	'fields' => array('id', 'username', 'password', 'name'),
	'order' => array('id DESC')
);

Save New Entry

// After saving you will receive the last saved entity.
$save = array(
	'id' => 10,
	'username' => 'jaime.ziga@gmail.com',
	'password' => 'Dude, it\'s private…',
	'name' => 'John Doe'
);
$user_saved = $SimplePDOWrapper->save('users', $save);

Update New Entry

// When updating it will only return true or false.
$update = array(
	'name' => 'Adrián Zúñiga'
);
$SimplePDOWrapper->update('users', $update, array(
	'conditions' => array(
		'id' => $user_saved['id']
	)
));

findOne & findAll

This methods receive 3 params in total, entity (table), options (see above) and assoc (boolean) to get an associative array or STDClass object.

// This findOne will return the one entity array or empty array.
$user = $SimplePDOWrapper->findOne('users', $options, $assoc = true);

// And findAll will return empty array or an array of STDClass objects.
$users = $SimplePDOWrapper->findAll('users', $options, $assoc = false);

delete & deleteAll

The only difference between delete and deleteAll is that 'delete' receives the options argument with 'conditions'.

// Options just needs compliant conditions.
$options = array(
    'conditions' => array(
        'id' => 666
    )
);

// Boolean
$deleted = $this->SimplePDOWrapper->delete('users', $options);

// Boolean
$deleted = $this->SimplePDOWrapper->deleteAll('users');

Switch database

Just like instantiating the class.

// Switch database with setDatabase() method
// and pass credentials in $conf array.
$conf = array(
	'database' => 'another_db',
	'username' => 'root',
	'password' => 'toor',
	'host' => 'localhost'
);

// Will return boolean.
$SimplePDOWrapper->setDatabase($conf);

Handling errors

Since it's internally set to handle errors you can handle them like this.

// As I mentioned before update method will return a boolean value.
$updated = $SimplePDOWrapper->update('users', $update, array(
	'conditions' => array(
		'id' => $user_saved['id']
	)
))

// Watching errors
if (!$updated || $SimplePDOWrapper->errors)
{
	var_dump($SimplePDOWrapper->errors['code']);
	var_dump($SimplePDOWrapper->errors['message']);
}
