Problem with json slim framework

I am making an api to do the integration of two different systems, the system sends me the following json:

cJson = [{"TESTE": "1"}]

I spent 3 days with a problem because I was not able to catch the json that the other system sent me via post with neither of these two methods below:

$dados = $request->getBody();

$dados = $request->getParsedBody();

I solved this problem and now I can get the json that the other system sends me with the seginte method:

$dados = (string) $resquest->getBody();

But this method just above returns me a string, and I need to transform it into an array or an object to insert it into the database. when I give an echo what is returned to me is just what I want to see right below:

echo $dados; 
resultado:   [{"TESTE": "1"}]

But when I use a json_decode it does not return anything to me returns null, example:

echo json_decode($dados);
resultado: null

Is it because it’s a string ? Is there any way I could fix this ? I’ve got the dice, but I can’t manipulate it into the bank...

There is nothing wrong with converting the string to JSON. The problem is that you cannot display the result with echo( ), because the return of the function json_decode( ) is an array.

Experiment with print_r( ):

print_r(json_decode('[{"TESTE": "1"}]'));
resultado: Array ( [0] => stdClass Object ( [TESTE] => 1 ) )

  • I don’t know why but I used it like this: json_decode($data, true).

To transform from a json object to an array in Php you must use the syntax: echo json_decode($dados, TRUE); .
You have to pass the TRUE parameter to transform it into array.

To print the information you must perform a foreach to access the values and then you can use echo, if you are trying to print directly the array must use the command print_r.
