I installed php + apache via Xampp. PHP is working, but does not recognize Json, does anyone know if I need to enable anything in php.ini?

Returns the error: Notice: Undefined index: jsoncallback

The return line is:

echo $_GET["jsoncallback"] . '(' . json_encode("Valor=" . $teste ) . ');';

The code works, I've circled the same code on the localhost of another computer, and also on a remote server, and it works perfectly, only on this computer I installed via Xampp does not work.

Thank you

The error you're getting:

Notice: Undefined index: jsoncallback

Indicates that the index in array $_GET with name jsoncallback does not exist.

When you do:

echo $_GET["jsoncallback"];

You are trying to access an array entry that does not exist.

To better control this you should make use of the isset () function of PHP:

if (isset($_GET["jsoncallback"])) {
  echo $_GET["jsoncallback"];
}
else {
  echo "Não foi localizado: jsoncallback";
}

Note: You should check that the URL of the page has a URL with the name jsoncallback .
