# FluentPDO [](http://travis-ci.org/envms/fluentpdo) [](https://codeclimate.com/github/fpdo/fluentpdo/maintainability)
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.
#### Version 1.x
The legacy release of FluentPDO. It is no longer supported and will not be maintained or updated.
This version works with PHP 5.4 to 7.1.
#### Version 3.x - alpha
This version is a full rewrite of Fluent from the ground up. Its main advantage is
significantly less memory usage and much greater performance in query building. It also places
a few additional restrictions to make queries easier to read and maintain. Documentation has also
been a very common request, and version 3 is being fully documented alongside development.
Details and metrics will be posted once available.
## Reference
[Sitepoint - Getting Started with FluentPDO](http://www.sitepoint.com/getting-started-fluentpdo/)
## Installation
### Composer
The preferred way to install FluentPDO is via [composer](http://getcomposer.org/).
Add the following line in your `composer.json` file:
"require": {
...
"envms/fluentpdo": "^2.2.0"
}
update your dependencies with `composer update`, and you're done!
### Download Zip
If you prefer not to use composer, download the latest release, create the directory `Envms/FluentPDO` in your library directory, and drop this repository into it. Finally, add:
```php
require '[lib-dir]/Envms/FluentPDO/src/Query.php';
```
to the top of your application. **Note:** You will need an autoloader to use FluentPDO without changing its source code.
## Getting Started
Create a new PDO instance, and pass the instance to FluentPDO:
```php
$pdo = new PDO('mysql:dbname=fluentdb', 'user', 'password');
$fluent = new \Envms\FluentPDO\Query($pdo);
```
Then, creating queries is quick and easy:
```php
$query = $fluent->from('comment')
->where('article.published_at > ?', $date)
->orderBy('published_at DESC')
->limit(5);
```
which would build the query below:
```mysql
SELECT comment.*
FROM comment
LEFT JOIN article ON article.id = comment.article_id
WHERE article.published_at > ?
ORDER BY article.published_at DESC
LIMIT 5
```
To get data from the select, all we do is loop through the returned array:
```php
foreach ($query as $row) {
echo "$row['title']\n";
}
```
## Using the Smart Join Builder
Let's start with a traditional join, below:
```php
$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:
```php
$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**:
```php
$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:
```mysql
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:
```php
$fluent->close();
```
## CRUD Query Examples
##### SELECT
```php
$query = $fluent->from('article')->where('id', 1)->fetch();
$query = $fluent->from('user', 1)->fetch(); // shorter version if selecting one row by primary key
```
##### INSERT
```php
$values = array('title' => 'article 1', 'content' => 'content 1');
$query = $fluent->insertInto('article')->values($values)->execute();
$query = $fluent->insertInto('article', $values)->execute(); // shorter version
```
##### UPDATE
```php
$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
```php
$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()`*
