Question

I need to get an array generated from a script php. I have Latitude and Longitude for each user in a database.
I take the values from the db with this code (file.php):

$query = "SELECT Latitude, Longitude FROM USERS";
$result=mysql_query($query);
$array=array();
while ($data = mysql_fetch_array($result)) {
    $array[]=$data['Latitude'];
    $array[]=$data['Longitude'];
}

echo $array;

and I call with ajax with this code:

$.post('./file.php',
     function( result ){    
         alert(result);
     });

but even if in the script php the array is correct (if I echo array[25] I obtain the right value) in Javascript I obtain “Undefined”.
How can I get the array in correct way??
thanks!

edit: after encoded with json_encode($array); in php and JSON.parse(result) in javascript seems not working.
In the console I have the array, but I can’t access to its values. (Array[0] gave me “undefined”).

Answer 1

use this

echo json_encode($array);

on server side

and

var arr=JSON.parse(result);

on client side
