The authoritative way to pass values from PHP to Javascript

Question

I guess I am looking for a best method of passing values: arrays, objects, JSON -- any data -- from PHP to javascript.

So far I've just seen:

   PHP - json_encode(value); 
   Javascript - eval()

and a variation of that by using json2.js or the alike.

Answer 1

PHP has:

• json_decode --> decode
• json_encode --> encode

JavaScript (json2.js) has:

• JSON.stringify --> encode
• JSON.parse --> decode
