Returning JSON from a PHP Script

Question

I want to return JSON from a PHP script.

Do I just echo the result? Do I have to set the Content-Type header?

Answer 1

If you need to get json from php sending custom information you can add this header('Content-Type: application/json'); before to print any other thing, So then you can print you custome echo '{"monto": "'.$monto[0]->valor.'","moneda":"'.$moneda[0]->nombre.'","simbolo":"'.$moneda[0]->simbolo.'"}';
