$.getJSON data into array

Question

i'm new in PHP and JAVASCRIPT.. i need to do a little script who takes the data from data.php with $.getJSON("data.php", function(json).. and push it into 2 arrays in the HTML file, to reuse them.

data.php produce this:

[[47,48,48,48,50,51,48,46,47,45,48,47],[25,23,22,21,19,21,24,25,27,29,31,28]]

at now i do this, but it doesn't run and i don't know how to do.

<!DOCTYPE html>
<html>
<head>
<script 
src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>
<script>
$(document).ready(function() {
    $.getJSON("data.php", function(json) {
            $row1[] = json[0];
            $row2[]= json[1];           

        }); 
    });

</script>
</head>
<body>

<div></div>

</body>
</html>

thanks to all guys ;)

I think you are confusing yourself with PHP and JS notations. $array[] means to append data to an array in PHP, not JavaScript. Whereas object[property] is to access an object's property value. However, $row1[] in your code is an invalid syntax as you have not defined any object $row1 nor provided any property within []. — Mikey

Your assignment syntax is wrong. You can't put [] at the end of a variable in Javascript.

$(document).ready(function() {
    $.getJSON("data.php", function(json) {
        var row1 = json[0];
        var row2 = json[1];
        // put code that uses row1 and row2 here
    }); 
});
