README

FluentPDO is a PHP SQL query builder using PDO. It's a quick and light library featuring a smart join builder, which automatically creates table joins for you.

Features

• Easy interface for creating robust queries
• Supports any database compatible with PDO
• Ability to build complex SELECT, INSERT, UPDATE & DELETE queries with little code
• Type hinting for magic methods with code completion in smart IDEs

Versions

Version 2.x

The stable release of FluentPDO and actively maintained. Officially supports PHP 7.3 to PHP 8.0, but it can work with previous versions of PHP 7.

Installation

Composer

Add the following line in your composer.json file:

"require": {
	...
	"ajur-media/fluentpdo": "^2.2.0"
}

update your dependencies with composer update, and you're done!

Getting Started

Create a new PDO instance, and pass the instance to FluentPDO:

$pdo = new PDO('mysql:dbname=fluentdb', 'user', 'password');
$fluent = new \AJUR\FluentPDO\Query($pdo);

Then, creating queries is quick and easy:

$query = $fluent->from('comment')
             ->where('article.published_at > ?', $date)
             ->orderBy('published_at DESC')
             ->limit(5);

which would build the query below:

SELECT comment.*
FROM comment
LEFT JOIN article ON article.id = comment.article_id
WHERE article.published_at > ?
ORDER BY article.published_at DESC
LIMIT 5

To get data from the select, all we do is loop through the returned array:

foreach ($query as $row) {
    echo "$row['title']\n";
}

Using the Smart Join Builder

Let's start with a traditional join, below:

$query = $fluent->from('article')
             ->leftJoin('user ON user.id = article.user_id')
             ->select('user.name');

That's pretty verbose, and not very smart. If your tables use proper primary and foreign key names, you can shorten the above to:

$query = $fluent->from('article')
             ->leftJoin('user')
             ->select('user.name');

That's better, but not ideal. However, it would be even easier to not write any joins:

$query = $fluent->from('article')
             ->select('user.name');

Awesome, right? FluentPDO is able to build the join for you, by you prepending the foreign table name to the requested column.

All three snippets above will create the exact same query:

SELECT article.*, user.name 
FROM article 
LEFT JOIN user ON user.id = article.user_id

Close your connection

Finally, it's always a good idea to free resources as soon as they are done with their duties:

$fluent->close();

CRUD Query Examples

SELECT

$query = $fluent->from('article')->where('id', 1)->fetch();
$query = $fluent->from('user', 1)->fetch(); // shorter version if selecting one row by primary key

INSERT

$values = array('title' => 'article 1', 'content' => 'content 1');

$query = $fluent->insertInto('article')->values($values)->execute();
$query = $fluent->insertInto('article', $values)->execute(); // shorter version

UPDATE

$set = array('published_at' => new FluentLiteral('NOW()'));

$query = $fluent->update('article')->set($set)->where('id', 1)->execute();
$query = $fluent->update('article', $set, 1)->execute(); // shorter version if updating one row by primary key

DELETE

$query = $fluent->deleteFrom('article')->where('id', 1)->execute();
$query = $fluent->deleteFrom('article', 1)->execute(); // shorter version if deleting one row by primary key

Note: INSERT, UPDATE and DELETE queries will only run after you call ->execute()
