Connect to serial port with PHP
Inspired by PHP-Serial, I simplify it and include composer.json to install via composer.
Actually, it works on linux. This library is suitable for working with Arduino.
composer require "lepiaf/serialport"
You can check a full example in example folder. It contains a basic Arduino sketch and php file to read it.
Instantiate a new SerialPort object with a parser and configure tty.
<?php
use lepiaf\SerialPort\SerialPort;
use lepiaf\SerialPort\Parser\SeparatorParser;
use lepiaf\SerialPort\Configure\TTYConfigure;
$serialPort = new SerialPort(new SeparatorParser(), new TTYConfigure());
$serialPort->open("/dev/ttyACM0");
while ($data = $serialPort->read()) {
echo $data."\n";
if ($data === "OK") {
$serialPort->write("1\n");
$serialPort->close();
}
}For mac os, you must use TTYMacConfigure. It will use stty -f instead of stty -F.
