I2C PHP Extension
=================

[](#i2c-php-extension)

The I2C PHP Extension provides an object-oriented wrapper to the [i2c-dev](https://www.kernel.org/doc/Documentation/i2c/dev-interface) Linux Module that gives users the ability to write code that interacts with external hardware using the [I2C](https://en.wikipedia.org/wiki/I%C2%B2C) protocol.

Requirements
------------

[](#requirements)

- PHP >= 8.0 (either NTS or ZTS version);
- libi2c-dev;

> **Note:** if you are using this extension on Raspbian or Raspberry Pi OS, the user executing the script **must**belong to the **i2c** group or you may run into "Permission denied" errors.

On **Raspbian** or **Raspberry Pi OS**:

**PHP 8.0**:

```
sudo apt install php8.0-cli php8.0-dev php8.0-phpdbg libi2c-dev
```

**PHP 8.1**:

```
sudo apt install php8.1-cli php8.1-dev php8.1-phpdbg libi2c-dev
```

Building
--------

[](#building)

```
phpize
./configure
make
make test
```

Stubs
-----

[](#stubs)

After changing any of the [stubs](stubs/), the main [stub file](phpi2c.stub.php) must be updated by running the command below.

```
php stubs/update-main-stup.php
```

Once the stub is updated, the regular build process can be executed.

**Note:** The main stub file ([phpi2c.stub.php](phpi2c.stub.php)) is a generated file, edit the files on the [stubs](stubs/) folder instead.
