Question

I’m trying to get a PHP array with AJAX and turn it into a JSON array.

Right now in the external file I’m echoing the php array with JSON encoding:

echo json_encode($palabras);

Then on the main file I get the response and assign it to variable “jsarray “;

success:function(data_response){
    jsarray = data_response;
    }});

However I can’t access jsarray as an array. How can I turn it into a proper array I can access?

If you are 100% certain you can trust the contents of data_response, you can simply evaluate it.

I don’t know what library you are using, but that should be something like jsarray = eval(data_response.responseText);

WARNING: This does pose a security risk if a third party can inject data into data_response. Since it’s a simple eval(), any javascript code can be executed.

I believe that most modern webbrowsers provide a JSON library to work around this issue. You should be able to use JSON.parse(data_response.responseText) in that case. However, that will not work on all browsers.
