Pass a PHP array to a JavaScript function [duplicate]

Answer 1

Use JSON.

In the following example $php_variable can be any PHP variable.

In your code, you could use like the following:

drawChart(600/50, , ...)

In cases where you need to parse out an object from JSON-string (like in an AJAX request), the safe way is to use JSON.parse(..) like the below:

var s = "";
var obj = JSON.parse(s);
