Javascript-форум - Highstock не рисует график

Это код json.php

<?php
header("content-type: application/json");
define('HOST', 'localhost');
define('USER', 'root');
define('PASSWORD', 'password');
define('NAME_BD', 'bd');
$connect = mysql_connect(HOST, USER, PASSWORD)
or die("die"
.mysql_error( ));
mysql_select_db(NAME_BD, $connect)
or die ("wtf"
.mysql_error( ));
$result = mysql_query("SELECT UNIX_TIMESTAMP(`Time`) * 1000 as datetime, `Current A` as A FROM `Table`")
or die ("die".mysql_error( ));
while ($row = mysql_fetch_array($result)) {
$data[] = $row['datetime'];
$datab[] = $row['A'];
}
echo '?(' . "\n" . '['. "\n";
$count = count($data);
for ($i=0; $i<$count; $i++)
{
echo '['. str_replace('"', "", json_encode($data[$i], JSON_HEX_APOS)) . ',' . str_replace('"', "", json_encode($datab[$i], JSON_HEX_APOS)) .']' . ',' . "\n";
}
echo ']);';
?>

А это stock.html

При обновлении страницы пустота.
В чем может быть проблема?
