Regular Expression Pattern Parsing ifconfig

This following gist allows you to easily parse the output of ifconfig.

	<?php

	function ifconfig() {
	preg_match("/^([A-z]\\d)\s+Link\s+encap:([A-z]\)\s+HWaddr\s+([A-z0-9:]\).\".
	"inet addr:([0-9.]+).\Bcast:([0-9.]+).\Mask:([0-9.]+).*".
	"MTU:([0-9.]+).\Metric:([0-9.]+).\".
	"RX packets:([0-9.]+).\errors:([0-9.]+).\dropped:([0-9.]+).\overruns:([0-9.]+).\frame:([0-9.]+).*".
	"TX packets:([0-9.]+).\errors:([0-9.]+).\dropped:([0-9.]+).\overruns:([0-9.]+).\carrier:([0-9.]+).*".
	"RX bytes:([0-9.]+).\$(.\)$.TX bytes:([0-9.]+).\$(.\*)$".
	"/ims", $int, $regex);


	if( !empty($regex) ){


	$interface = array();
	$interface['name'] = $regex[1];
	$interface['type'] = $regex[2];
	$interface['mac'] = $regex[3];
	$interface['ip'] = $regex[4];
	$interface['broadcast'] = $regex[5];
	$interface['netmask'] = $regex[6];
	$interface['mtu'] = $regex[7];
	$interface['metric'] = $regex[8];


	$interface['rx']['packets'] = $regex\[9];
	$interface['rx']['errors'] = $regex\[10];
	$interface['rx']['dropped'] = $regex\[11];
	$interface['rx']['overruns'] = $regex\[12];
	$interface['rx']['frame'] = $regex\[13];
	$interface['rx']['bytes'] = $regex\[19];
	$interface['rx']['hbytes'] = $regex\[20];


	$interface['tx']['packets'] = $regex\[14];
	$interface['tx']['errors'] = $regex\[15];
	$interface['tx']['dropped'] = $regex\[16];
	$interface['tx']['overruns'] = $regex[17];
	$interface['tx']['carrier'] = $regex[18];
	$interface['tx']['bytes'] = $regex[21];
	$interface['tx']['hbytes'] = $regex[22];


	$interfaces[] = $interface;


	}

	return $interfaces;
	}
