Question

I have a PHP String like this:

$string = 'a => 1 , b => 2 , c => 3 , d => 4';

which I have built from data from a database, where each "x => y" represents an associative relationship between x and y.

I am then transferring this string to the html document (JQuery) and attempting to make an array out of it in JavaScript, so that I may process on the client side.

QUESTION:

Is it possible to create a JavaScript Array out of a string?
For example I need to be able to retrieve the values in the array by calling 'alert(array["c"]);' or something similar.

NOTE – feel free to alter the semantics of the above string ($string) as necessary.

Any help appreciated guys….

Answer 1

PHP Code

(for instance, a file, like array.php):

$array=array(
    'a'=>'I am an A',
    'param2_customname'=>$_POST['param2'],
    'param1'=>$_POST['param1']
);
echo json_encode($array);

---

jQuery code:

$.post('array.php', {'param1': 'lol', 'param2': 'helloworld'}, function(d){
   alert(d.a);
   alert(d.param2_customname);
   alert(d.param1);
},'json');

You can use this for arrays, remember the 'json' tag at the end of the request everytime.
