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 ``` License ------- [](#license) MIT, see [LICENSE file](LICENSE). ### Acknowledgments [](#acknowledgments) - [libpcap](https://github.com/the-tcpdump-group/libpcap) by The Tcpdump Group, BSD licensed. ### Contributing [](#contributing) Bug reports (and small patches) can be submitted via the [issue tracker](https://github.com/rtckit/php-pcap-ffi/issues).
