//string json contendo os dados do paciente
 $json_str = 'http://xxx.70.67.242:4040/api/laudos/95000,75298848087';
//faz o parsing na string, gerando um objeto PHP
 $obj = json_decode($json_str);

//imprime o conteúdo do objeto 
echo "n_recep2: $obj->n_recep2<br>"; 
echo "nome_pac: $obj->nome_pac<br>"; 
echo "resultado: $obj->resultado<br>";
php json web-service

  • But you’re parsing a url instead of the json string. Understand this?

  • I have to consume this url that is there, it is third party

  • In this case, you have to make a request. You don’t just make a string with the url and wait for it to do the request. xD. I’ll formulate an answer for you. Know Curl?

As already mentioned in my comment, you are parsing a string simple that received the URL of the webservice you want to consume:

//string json contendo os dados do paciente
 $json_str = 'http://xxx.70.67.242:4040/api/laudos/95000,75298848087';
//faz o parsing na string, gerando um objeto PHP
 $obj = json_decode($json_str);

It won’t work! At least not that way.

What you need is to make a request that will return this JSON. To do so, we use the cURL:

$curl = curl_init();
curl_setopt_array(
    $curl,
    array(
        CURLOPT_URL => 'http://xxx.70.67.242:4040/api/laudos/95000,75298848087',
        CURLOPT_RETURNTRANSFER => true
    )
);

$json_str = curl_exec($curl);

$obj = json_decode($json_str);
$obj = $obj[0];

//print_r($obj);

echo "n_recep2: $obj->n_recep2<br>";
echo "nome_pac: $obj->nome_pac<br>";
echo "resultado: $obj->resultado<br>";

Of course this is a simple request. Curl goes much further! I recommend reading the Curl documentation in the PHP manual.
