[jQuery] JSON , PHP, MySQL, and jQuery

[Renato Untalan]

I'm having trouble parsing JSON in Javascript.

The response i'm getting from PHP when making a request is:
[
{'name': 'John', 'lastName': 'Doe','age':'25', 'height': '170',
'weight': '120'},
{'name': 'Jane', 'lastName': 'Doe','age':'26', 'height': '175',
'weight': '121'},
{'name': 'Jack', 'lastName': 'Doe','age':'27', 'height': '180',
'weight': '122'} ]

How would I go about parsing this in Javascript?  Am I not encoding it
correctly on the PHP Side?

Here's my JAVASCRIPT:
        $.get("includes/functions_inside.php", {"function" : "getAppList"},
                function(data, textStatus){
                        alert( data[0] );
                }
        );

Here's my PHP:

        $AppListQuery = $insideDB->customQuery($query);
        $rows = array();
        while($r = mysql_fetch_assoc($AppListQuery)) {
            $rows[] = $r;
        }
        print json_encode($rows);

Thanks in advance!
