PHP Array from MYSQL to Javascript Object using JSON

I am starting to wonder where my head is at because I should have this on smash...

Scenario:

MySQL DB Table  > 'Sites'

Columns > 'Siteid(INT)','Location(Varchar)','Address(varchar)','PostalCode(varchar)'...etc

Trying to get all rows from table into PHP array, encode to json.

I would like to access this data in javascript via sitesArray[Location].Address would give me 123 Street

sitesArray[Toronto] > 'Address' : '123 Street', 'PostalCode' : '12345'

sitesArray[Montreal] > 'Address' : '0987 Street', 'PostalCode' : '09876'

I can get all rows from db no problem...however I am stuck on this blasted array thing...I cant get it into an associative array...whenever I encode the straight array from mysql it is invalid json, further more there is no index either integer or literal...

PHP DB TO ARRAY TO JSON

$result = mysql_query("SELECT * from Recommendations.Satellite_Sites;");
while($row= mysql_fetch_array($result)){
        $fullSiteDetails[$row['Site']] = array("site" => $row["Site"],"city" => $row["Site_City"], "address" => $row["Site_Address"], "postalcode" => $row["Site_PostalCode"], "phone"=>$row["Site_Phone"],"fax"=>$row["Site_Fax"]);
    }

    die(json_encode($fullSiteDetails));

this is my array building in the while loop during db look up

$fullSiteDetails[] = array("site" => $row["Site"],"city" => $row["Site_City"], "address" => $row["Site_Address"], "postalcode" => $row["Site_PostalCode"], "phone"=>$row["Site_Phone"],"fax"=>$row["Site_Fax"]);

JSON json_encode($fullSiteDetails)....>

{
site: "Ajax",
city: "Ajax",

postalcode: "L1Z xxx",
phone: "(905)-xxx-xxxx",
fax: "(905)-xxx-xxxx"
},
{

postalcode: "xxx xxx",

},
{
site: "TWH",
city: "Toronto",
address: "xxxxxxxxxxxxxxxxxxxxxxxxx",
postalcode: "xxx xxx",
phone: "(416)-xxx-xxxx",
fax: "(416)-xxx-xxxx"
}
]

Not only are the keys unqouted but I also would like to get this into an associative array...

in javascript I am doing this:

var fullSiteDetails = {};
fullSiteDetails = '<?php echo json_encode($fullSiteDetails) ?>';

in the console:

fullSiteDetails[0]
"{"
fullSiteDetails[Ajax]
VM8497:2 Uncaught ReferenceError: Ajax is not defined
fullSiteDetails['Ajax']
undefined

What am I missing or not cluing into?

Thanks for your time.
