array com problema json multidimensional - php

Question

I am trying to get a data that is in an array inside another array, I did a search by the forum and google and I made several attempts without success.
It seems like an easy catch but I'm breaking my head all day and I can not.
I'm leaving below my JSON code and my last attempt to pass to PHP.
Thankful.
CODE JSON:
{
"ordens_de_servico": [
{
"oser_numero_os": 23932944,
"oser_nome_solicitante": "ED PI - CAMPO MAIOR",
"oser_dt_abertura": "27/03/2018",
"oser_pontos_refer_endereco": null,
"oser_observ_reclamacao": null,
"oser_prioridade": null,
"servico": {
"serv_cod_servico": 60,
"serv_descr_servico": "CORTE POR DEBITO"
},
"cliente": {
"nome": "ANTONIO WELTON DA SILVA OLIVEIRA",
"telefone": " "
},
"unidade_consumidora": {
"unid_ident_uc": 10945024,
"logr_nome_logr_expandido": null,
"medidor": "A2006171",
"latitude": " -4.711808",
"longitude": "-41.793455"
},
"faturas": [
{
"total_fatura": "23.01"
},
{
"total_fatura": "17.88"
},
{
"total_fatura": "23.01"
},
{
"total_fatura": "21.9"
},
{
"total_fatura": "22.92"
}
]
}
]
}
CODE PHP
<?php
// Read JSON file
$json = file_get_contents('oss.json');
//Decode JSON
$json_data = json_decode($json,true);
//Print data
print_r($json_data);
$os = $json_data['ordens_de_servico'][0]['oser_numero_os']. PHP_EOL;
$data = $json_data['ordens_de_servico'][0]['oser_dt_abertura']. PHP_EOL;
$cod_serv = $json_data['ordens_de_servico']['servico'][0]['serv_cod_servico']. PHP_EOL;
$total_fatura = $json_data['ordens_de_servico']['faturas'][0]['total_fatura']. PHP_EOL;
echo $os."<p>";
echo $data."<p>";
echo $cod_serv."<p>";
echo $total_fatura."<p>";
?>
I tried looping unsuccessfully on the fatura
$json_data = json_decode($json,false);
foreach ( $json_data->ordens_de_servico as $valor){
echo 'FATURA:'.$valor->faturas->total_fatura."<p>".PHP_EOL;
echo PHP_EOL;
}

At a minimum, you are missing the [0] on these two lines:
$cod_serv = $json_data['ordens_de_servico']['servico'][0]['serv_cod_servico']. PHP_EOL;
$total_fatura = $json_data['ordens_de_servico']['faturas'][0]['total_fatura']. PHP_EOL;
They need to be:
$cod_serv = $json_data['ordens_de_servico'][0]['servico']['serv_cod_servico']. PHP_EOL;
$total_fatura = $json_data['ordens_de_servico'][0]['faturas'][0]['total_fatura']. PHP_EOL;
Example of looping through elements in arrays:
foreach($json_data['ordens_de_servico'] as $key => $value){
echo $value["oser_numero_os"];
foreach($json_data['ordens_de_servico'][$key]['faturas'] as $index => $row){
}
}
