$node $dom->createElement("markers");
$parnode $dom->appendChild($node);



try{
    
$stringconnection = new PDO("mysql:host=localhost;dbname=mydb"'root''');
    
$stringconnection->setAttribute(PDO::ATTR_ERRMODEPDO::ERRMODE_EXCEPTION);

    
$cmd $stringconnection->prepare("SELECT storename,address,lat,lng ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(-122) ) + sin( radians(37) ) * sin( radians( lat ) ) ) ) AS distance FROM tblstore HAVING distance < '%s' ORDER BY distance LIMIT 0 , 20",
