Question

I\'m trying to create a common constants file to share between php and javascript, using JSON to store the constants. But I\'m wondering why pass the JSON from PHP to javasc

Answer 1

json_encode is a function that converts a PHP array into a JSON string, and nothing more. Since your $json_obj variable is already a JSON string, no further conversion is needed and you can simply echo it out.

To get to your $json_obj string from an array your code would have looked like this

$json_array = array(
    "const1" => "val",
    "const2" => "val2"
);

$json_obj = json_encode($json_array);
