It would help if you would state in which line do you get this error. Thanks — Danilo Radenovic, Dec 26 '12 at 08:27
Looks like a text encoding problem. Unicode BOM? Or some invisible control or whitespace characters? — Thilo, Dec 26 '12 at 08:31
m getting error in this line....var data = JSON.parse(data.responseText); — Deedar, Dec 26 '12 at 08:34
Can you print `data.responseText` and also `getLocation.php`. Looks like a non-utf8 character finds its way in the response. — web-nomad, Dec 26 '12 at 08:36
this is get_location.php file setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION ); $sth = $db->query("SELECT * FROM data"); $locations = $sth->fetchAll(); echo json_encode( $locations ); } catch (Exception $e) { echo $e->getMessage(); } ?> — Deedar, Dec 26 '12 at 08:37
It signifies a non-utf8 character has been encountered. Can you follow the step in this post before doing `json_encode` in your `getLocation.php` file and see if it solves the issue - http://stackoverflow.com/questions/1401317/remove-non-utf8-characters-from-string — web-nomad, Dec 26 '12 at 08:40
now m getting this error in same line::: Uncaught SyntaxError: Unexpected token — Deedar, Dec 26 '12 at 08:42

Try this and see if this helps:

<?php
require 'config1.php';

function removeNonUTF8( &$value, $key ) {
    $regex = <<<'END'
/
  (
    (?: [\x00-\x7F]
    |   [\xC0-\xDF][\x80-\xBF]
    |   [\xE0-\xEF][\x80-\xBF]{2}
    |   [\xF0-\xF7][\x80-\xBF]{3}
    )+                              # ...one or more times
  )
| .                                 # anything else
/x
END;

    $value = preg_replace( $regex, '$1', $value );
}

try { 
    $db = new PDO($dsn, $uname, $pass); 
    $db->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION ); 

    $sth = $db->query("SELECT * FROM data"); 
    $locations = $sth->fetchAll(); 

    foreach( $locations as $location ) {
        array_walk( $location, 'removeNonUTF8' );
    }

    echo json_encode( $locations ); 
} catch (Exception $e) { 
    echo $e->getMessage(); 
}
?>

Also, if this does not work, can you print your $locations variable so that we can see the structure.

Hope this helps.

this error occr when i run this code::: Parse error: syntax error, unexpected T_SL in C:\xampp\htdocs\google_api\get_location.php on line 5 – Deedar Dec 26 '12 at 08:54
**There should be no whitespace** before `END;` in the function `removeNonUTF8`. Remove all spaces, tabs etc before the `END;` – web-nomad Dec 26 '12 at 08:57
Also, **no whitespace after** `$regex = <<<'END'`. – web-nomad Dec 26 '12 at 08:59
You sure there is no whitespace before/after `$regex = <<<'END'` and `END;`? – web-nomad Dec 26 '12 at 09:00
function removeNonUTF8( &$value, $key ) { $regex =<<<'END' / ( (?:[\x00-\x7F] |[\xC0-\xDF][\x80-\xBF] |[\xE0-\xEF][\x80-\xBF]{2} |[\xF0-\xF7][\x80-\xBF]{3} )+ ) |. /x END; $value = preg_replace( $regex, '$1', $value ); } check this there is no space – Deedar Dec 26 '12 at 09:02
See this - http://phpfiddle.org/main/code/6fi-r2c. If this doesn't work, i am sorry :(. – web-nomad Dec 26 '12 at 09:05
