Need help in php array to json

Question

Having an array

`Array
(
    [0] => Array
        (
            [operative] => 2
            [start] =>  01:00:00
            [end] =>  13:00:00
            [color] => 543939
        )

    [1] => Array
        (
            [operative] => 3
            [start] =>  08:00:00
            [end] =>  09:00:00
            [color] => 52e612
        )

)

`

need to change this into JSON so I use json_encode(), I get a string
[{"operative":"2","start":" 01:00:00","end":" 13:00:00","color":"543939"},{"operative":"3","start":" 08:00:00","end":" 09:00:00","color":"52e612"}]

but when I am using JSON into JavaScript by function $.parseJSON() or JSON.parse(), both are giving me not defined.

ok I have used it like this

options1 = '[{"operative":"2","start":" 01:00:00","end":" 13:00:00","color":"543939"},{"operative":"3","start":" 08:00:00","end":" 09:00:00","color":"52e612"}]'
options1 = $.parseJSON(options1);
alert($.param(options1));

But alert is showing me undefined=&undefined=

Make sure that the data you retrieve is, in fact, the json string and nothing more than that (console.log() it). Your json itself is valid, so $.parseJSON( data ) should return an array if you are passing that string as an argument. — Sumurai8

If you are using $.parseJSON() -function, the parseable data should be string:

var json = '[{"operative":"2","start":" 01:00:00","end":" 13:00:00","color":"543939"},{"operative":"3","start":" 08:00:00","end":" 09:00:00","color":"52e612"}]';

console.log($.parseJSON(json));

It looks like you're echo-ing that json encoded string into your javascript. You can do this, and just leave the quotes out:

var options = <?= json_encode($array); ?>;

JSON is an acronym for JavaScript Object Notation. Echoing it into a JS script results in valid javascript arrays and object literals. No need to parse it at all.

Until you show your code I am assuming that this is what you did:

var object = $.parseJSON(<?php echo json_encode($array)?>);

and this wont work because parseJSON expects a string as a parameter.

so the solution will be:

var object = $.parseJSON('<?php echo json_encode($array)?>');

Note that it is surrounded by quotes.

But... why parse it if JSON is actually a JavaScript code? Just do var data = <?= json_encode($data) ?>;, no parsing needed!

JSON.parse() expects the argument to be a string. Make your JSON data a string by surrounding it with 'single-quotes' (because you've used "double quotes" inside the JSON already)

Or leave the quotes, and don't parse valid JSON. JavaScript Object Notation is valid JavaScript, just echo it unquoted!

Use parseJSON()

done(function (jsonresponse) {
var obj = $.parseJSON(jsonresponse);        
console.log(obj);
};
