<?php
// For example if you need to print a fontawesome icon on an image... or as dropdown in a select box...

$in = file_get_contents('_variables.scss');
$out = array();
preg_match_all("/fa-var-(.*): \"\\(.*)\";/", $in, $out);
$result = array();
$count=0;
foreach($out[1] as $name) {
        $result[$name] = $out[2][$count];
        $count++;
