arduino-php-wrapper (inspired by Johnny-Five JS)

, _(*1)

If you are wondering how to control the Arduino serial port via PHP, here is the solution. The arduino:// wrapper is a easy and straightforward way to write and read data from Arduino., _(*2)

Install

composer require marabesi/arduino-php-wrapper

Usage

To read data from Arduino serial just use the regular I/O functions in PHP such as fread or file_get_contents, _(*3)

``` php \Arduino\Wrapper::register();, _(*4)

//reads data from Arduino $resource = fopen('arduino://ttyUSB0', 'r+'); print fread($resource, 1024);, _(*5)


Or if you prefer, you can use **file_get_contents** and get the same result

``` php
print file_get_contents('arduino://ttyUSB0');

To write data in the Arduino serial is as easy as it could be, _(*6)

``` php \Arduino\Wrapper::register();, _(*7)

//writes data to Arduino $resource = fopen('arduino://ttyUSB0', 'r+'); print fwrite('hello Arduino');, _(*8)


``` php
\Arduino\Wrapper::register();

print file_put_contents('arduino://hello Arduino');

OOP

You can use in your project in a OOP style, _(*9)

Sending data

``` php $writer = new Arduino\Writer(new Arduino\Wrapper()); $bytes = $writer->out('ttyUSB0', 'from oop');, _(*10)


### Reading data

``` php
$arduino = new \Arduino\Wrapper();

$writer = new \Arduino\Reader($arduino);
while (true) {
    print $writer->from('/dev/cu.usbmodem1411');
}
