Return file data . lua in PHP in array form

Question

I need to access some data stored in a file .lua in PHP.

This is the contents of the archive meu_arquivo.lua:

tbl = {
    [22004] = {
        unidentifiedDisplayName = "Sapato",
        unidentifiedResourceName = "»÷µé",
        unidentifiedDescriptionName = {
            "Item não identificado. Pode ser identificado com uma [Lupa]."
        },
        identifiedDisplayName = "Botas Temporais DES",
        identifiedResourceName = "½Ã°£ÀǼÕÀçÁÖºÎÃ÷",
        identifiedDescriptionName = {
            "Botas incríveis que devem ter sido criadas há muito tempo, mas nunca foram usadas.",
            "^0000ffDEX +35.^000000",
            "Tipo: ^777777Calçado^000000",
            "Defesa: ^77777725^000000",
            "Peso: ^777777350^000000",
            "Nível necessário: ^77777799^000000",
            "Classes: ^777777Todas as classes^000000"
        },
        slotCount = 1,
        ClassNum = 0
    },
    [22005] = {
        unidentifiedDisplayName = "Sapato",
        unidentifiedResourceName = "»÷µé",
        unidentifiedDescriptionName = {
            "Item não identificado. Pode ser identificado com uma [Lupa]."
        },
        identifiedDisplayName = "Botas Temporais SOR",
        identifiedResourceName = "½Ã°£ÀÇÇà¿îºÎÃ÷",
        identifiedDescriptionName = {
            "Botas incríveis que devem ter sido criadas há muito tempo, mas nunca foram usadas.",
            "^0000ffLUK +35.^000000",
            "^0000ff+20 de Crítico.^000000",
            "Tipo: ^777777Calçado^000000",
            "Defesa: ^77777725^000000",
            "Peso: ^777777350^000000",
            "Nível necessário: ^77777799^000000",
            "Classes: ^777777Todas as classes^000000"
        },
        slotCount = 1,
        ClassNum = 0
    }
}

Example: I want to return the value of tbl > 22004 > unidentifiedDisplayName that would be Sapatoas if it were an array(array) proper to PHP:

<?= $meu_arquivo['tbl']['22004']['unidentifiedDisplayName']; // mostra "Sapato" ?>

I don’t know the syntax/language of this file to point my research more accurately. My only reference is that the file is read via MOON by the original application (Game).

As much as it bears a resemblance to JSON, the function json_decode didn’t work for this file.

Any help is welcome!

One solution is to use the Lua extension for PHP: http://php.net/manual/en/class.lua.php

Follow an example using your file .lua as an input:

<?php
$lua = new Lua('./file.lua');
var_dump($lua->tbl[22004]['unidentifiedDisplayName']);

Produces the following output:

string(6) "Sapato"

I’ll also leave here an example of installing the moon extension in PHP (of course depending on your production environment the instructions may vary, but as I had to quickly have an environment to run the proposed solution, I thought it might be useful to share)

FROM php:latest

RUN apt-get -y update \
 && apt-get -y install lua5.2 liblua5.2-0 liblua5.2-dev \
 && cp /usr/include/lua5.2/lua.h /usr/include/ \
 && ln -s /usr/include/lua*.*/ /usr/include/lua \
 && cp /usr/lib/x86_64-linux-gnu/liblua5.2.a /usr/lib/liblua.a \
 && cp /usr/lib/x86_64-linux-gnu/liblua5.2.so /usr/lib/liblua.so \
