Undefined Property: stdClass

Question

I have a question regarding an array. I have the following information:

What I’m not getting is to go through the other array. Below is the code.

 foreach ($file_contents->retorno->contatos as $contatos) {
echo "{$contatos->contato->codigo} - {$contatos->contato->nome} - ";
foreach ($contatos->contato->tiposContato as $contato) {
    dd($contato->tipoContato->descricao);
}
echo '<br>';
 }

When I put the dd it works.

When printing with echo he of error.

foreach ($file_contents->retorno->contatos as $contatos) {
echo "{$contatos->contato->codigo} - {$contatos->contato->nome} - ";
foreach ($contatos->contato->tiposContato as $contato) {
    echo $contato->tipoContato->descricao;
}
echo '<br>';

}

Answer 1

First of all, I recommend you use the foreach instead of a for() to iterate an array. (even if you lose a little performance, it makes reading much easier)

There is the possibility of some of the data inside your $file_contents->retorno->contatos not having the property tiposContato, therefore, I recommend using a isset() to print the property only if it exists.

foreach ($file_contents->retorno->contatos as $contatos) {
    echo "{$contatos->contato->codigo} - {$contatos->contato->nome} - ";

    if(isset($contatos->contato->tiposContato)){
        foreach ($contatos->contato->tiposContato as $contato) {
            echo isset($contato->tipoContato) ? $contato->tipoContato->descricao) : false;
        }
    }

    echo '<br>';
}

To verify at what point the inconsistency may be happening you can give a dd() conditional

if(!isset($contatos->contato->tiposContato)){
    dd($contatos->contato);
}
