PHP array to jquery array via JSON

Question

Im having a little confusion why the following is not working.

get.php

Answer 1

data contains a string of the JSON, so arr[2] will be the third character in the string. You need to use $.parseJSON(data).

Answer 2

Your PHP is claiming that the JSON is HTML. You need to explicitly say it is JSON to get jQuery to handle it as such automatically.

header("Content-type: application/json");

Answer 3

you can't gave the data value to the array.

 $.get("get.php", function(data){
     alert(data[2]);
}, "json");

Answer 4

Send the json header in php via header('Content-type: application/json'); so jQuery should automatically decode your json data.
