# gphpio

This library provides a nice OO interface to interact with the GPIO pins of RaspberryPi (2).

## Setup

For RaspberryPi (2) please make sure that the files at `/sys/class/gpio` are owned by `root:gpio` and that the user which

executes the PHP script using this library is also in the group `gpio`. This should be the case anyway as long as you have

already run the `raspi-config` tool on installation.

Else you may need to apply the following changes [described here](http://www.element14.com/community/message/139528/l/re-piface-digital-2--setup-and-use#139528).

## Example

The "Hello world" LED-blink script would look like that:

```php

$model = new RPi();

$gpio = new GPIO($model);

$pin = 17;

if($gpio->isExported($pin) === false)

	$gpio->export($pin, GPIO::MODE_OUTPUT);

echo 'This is a ' , $model->getName() , PHP_EOL;

for($i = 0; $i < 10; ++$i) {

	$gpio->write($pin, 1);

	echo 'The pin is now: ' , $gpio->read($pin) , PHP_EOL;

	sleep(1);

	$gpio->write($pin, 0);

	echo 'The pin is now: ' , $gpio->read($pin) , PHP_EOL;

	sleep(1);

}

$gpio->unexport($pin);

```
