从PHP中的数组中获取JSON值

I have the following JSON

      [
           {
          "part_number": {
             "id": "1",
             "text": "962-00031-17A004"
          },
          "categoria": null,
          "codigo_cti": "",
          "fabricante": null,
          "modelo": null,
          "numero_serie": "",
          "obs": ""
       }
    ]

And I use the code bellow to collect data from it. If I select to extract obs, it works fine. I would like to know how can I collect the text and ID from part_number.

$produtos = json_decode($_POST['produtos'], true);  

foreach($produtos as $produto){
    echo $produto["obs"]; //WORKS FINE
    echo $produto["part_number"]["text"]; //DOES NOT WORK
}

    Turn it into an object and not array first - its easier and Object Orientated is the way to go.

    Here is a working example;

    $json = '[
           {
    
          "part_number": {
    
             "id": "1",
    
             "text": "962-00031-17A004"
    
          },
    
          "categoria": null,
    
          "codigo_cti": "",
    
          "fabricante": null,
    
          "modelo": null,
    
          "numero_serie": "",
    
          "obs": ""
    
       }
    
    ]';
    
    $produtos = json_decode($json, false);  
    
    
    foreach($produtos as $produto){
       echo $produto->part_number->id;
    }
