The Package 🚀

The package provides several classes to extract Electric Bills. The project is separated in several classes. Each class extract an specific type of bill.

Using the Package 🎮

Each extractor class have two main methods: fromFile and fromContent, and both returns an associative-array with all the bill data.

Example 🔧

Here, we will use the Extractor RGE, but it apply to any other extractor

<?php

use NystronSolar\ElectricBillExtractor\BR\RS\ExtractorRGE;

$extractor = new ExtractorRGE(/* You can put an custom PDF Parser (from smalot/pdfparser Package) */);
$output = $extractor->fromFile('my_bill.pdf'); // You can also use the fromContent() method, that does the same, but accepting an PDF Content String.

echo json_encode($output);

This should return something like that:
