Error:

Notice: Trying to get Property of non-object in C: xampp htdocs json get_json.php on line 6

My php code:

<?php
$get = 'https://maps.googleapis.com/maps/api/place/autocomplete/json?&location=-18.866269,-41.9558537&radius=1&input=Rua%20Trin&types=address&language=pt_BR&key=dsdfdsfg21321erwr4rgf34gerg443g43hg34yh5t43tf3';

$VarJson = file_get_contents( $get );
        $obj = json_decode($VarJson, true);
        $VarRetorno =   $obj['predictions']['description']= $obj->description;
echo $VarRetorno;
?>

Json that is being returned:

I only need to take the fields description

php json array

  • Appear to be an array, try $obj['predictions']['description'] = $obj['description'];

  • @rray Returned this error now: Notice: Undefined index: Description in C: xampp htdocs json get_json.php on line 6

  • Is that line right? has two assignments one of them doesn’t seem correct ( $obj->description) pq basically you take a json value and try to assign it to yourself. $VarRetorno = $obj['predictions']['description']= $obj->description;

The "Predictions" field is an array so will have several "Description", if I understood what you want this should solve:

<?php
$get = 'https://maps.googleapis.com/maps/api/place/autocomplete/json?&location=-18.866269,-41.9558537&radius=1&input=Rua%20Trin&types=address&language=pt_BR&key=dsdfdsfg21321erwr4rgf34gerg443g43hg34yh5t43tf3';

$VarJson = file_get_contents( $get );
$obj = json_decode($VarJson, true);
$VarRetorno = array_column($obj['predictions'], 'description');
echo implode("<br>", $VarRetorno);
?>

If you only want the first you can change the row of the array_column to this:

if(isset($obj['predictions'][0])){
    $VarRetorno = array_column($obj['predictions'][0], 'description');
}else{
    // seu tratamento
}

  • returned it now: Notice: Array to string Conversion in C: xampp htdocs json get_json.php on line 8 Array

  • Line 8 = echo $Sweep;

  • yes careless my, as had spoken would be returned several "Description", if you want to join all just do so: echo implode("<br>", $Sweep);

  $get = file_get_contents( $get );

  //Decodificando a string e criando o json
  $json = json_decode($get, true);
  $json = $json["predictions"];
  $get = "";

  foreach($json as $item){
  $get .= $item["description"];
  $get .= "<br>";
  }

  echo $get;
?>
