Object of class stdClass could not be converted to string error

Question

I have the following string:

{\"Coords\":[{\"Accuracy\":\"65\",\"Latitude\":\"53.277720488429026\",\"Longitude\":\"-9.012038778269686\",\"Timestamp\":\"Fri J         


        

Answer 1

It was an old question, still answer to make it clear for someone who just encounters it like me.

try json_encode($traces);

in my case

return var_dump(json_encode($result[0]));

the result is:

string(34) "{"id":1,"content":"test database"}"

Answer 2

Try using this $decoded_traces=json_decode($traces, true);

instead of this $decoded_traces=json_decode($traces);

It will convert your stdClass to array. Note that $decoded_traces is array then you can use as you require.

Answer 3

Instead of

 $decoded_traces=json_decode($traces);
 echo $decoded_traces;

try

$decoded_traces=json_decode($traces, true);
print_r $decoded_traces;

Answer 4

You get the error because you are trying to turn a stdClass object into a string, something it doesn't support.

Instead of echo $decoded_traces try var_dump($decoded_traces) - that will give a diagnostic view of the object you've decoded (which I presume is what you wanted). You should find it looks like this

class stdClass#1 (2) {
  public $Coords =>
  array(5) {
    [0] =>
    class stdClass#2 (4) {
      public $Accuracy =>
      string(2) "65"
      public $Latitude =>
      string(18) "53.277720488429026"
      public $Longitude =>
      string(18) "-9.012038778269686"
      public $Timestamp =>
      string(39) "Fri Jul 05 2013 11:59:34 GMT+0100 (IST)"
    }
    [1] => (more of the same, edited for brevity)
    [2] =>
    [3] =>
    [4] =>
  }
  public $Scan =>
  string(8) "Whatever"
}

By default, json_encode will create stdClass objects like the above. If you would prefer an associative array, pass true as the second parameter to json_decode, e.g. $decoded_traces=json_decode($traces, true);

As a further aside, although stdClass can't be turned into a string, your own classes can - a class which implements the __toString magic method could be converted to a string!

Answer 5

use json_encode($traces) this will convert the array into the string. json_decode() is used to convert a string into array or object array

Answer 6

$decoded_traces is an object. You cannot simply echo an object, because that makes no sense.

If you want to debug the object, use var_dump($decoded_traces).
