Pcap Extension
--------------

[](#pcap-extension)

Whenever possible (or if using an older version of PHP), you should use the native [pcap PHP extension](https://github.com/rtckit/php-pcap-ext), this library is provided as an alternative to it for select/edge cases. Otherwise, the FFI based packet capture library is fully compatible with the `pcap` extension. As a result, all changes applied to the extension are reflected here too, and the library version will always match its extension counterpart.

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

[](#requirements)

This library makes use of features introduced as of PHP 7.4, it will not work with obsolete versions. Of course, the [PHP FFI extension](https://www.php.net/manual/en/book.ffi.php) must be installed and enabled.

The libpcap library must be installed on the target environment; some Linux distributions meddle with the library naming protocols and this can confuse the FFI initialization process. Should that be the case, one can set the `LIBPCAP_NAME` environment variable to the actual library name, or even the absolute path to the library's .so file for custom builds or non-standard directory layouts.

For example, for Debian Buster, one would set `LIBPCAP_NAME` to `libpcap.so.1.8.1`.

Install
-------

[](#install)

The recommended way to install this library is [through Composer](https://getcomposer.org). [New to Composer?](https://getcomposer.org/doc/00-intro.md)

This will install the latest supported version:

```
composer require rtckit/pcap-ffi:^0.6.5
```

Tests
-----

[](#tests)

Before running the test suite, make sure the user has the ability to capture network packets (root or `CAP_NET_RAW`).

```
make test
```
