mysqli查詢不返回JSON和Google Charts的結果

我在本地開發，一切正常。當我上傳到主機時，某些數據庫信息無法顯示。mysqli查詢不返回JSON和Google Charts的結果

這是aRodgersForm.php地方，做出詢問：

<?php 
require_once '../login.php'; 
$conn = new mysqli($hn, $un, $pw, $db); 
if ($conn->connect_error) die($conn->connect_error); 

var_dump($conn); 

$req = mysqli_query($conn,"SELECT * FROM arodgers"); 

print_r($req); 

if(!$req) die('Database access failed: ' . $conn->error); 

$CMP = array(); 

foreach($req as $result) 
{ 
    $CMP[] = array((int)$result['SEASON'], 
        (int)$result['GP'], 
        (int)$result['CMP'], 
        (int)$result['ATT'], 
        (double)$result['CMP%'], 
        (double)$result['AVG'], 
        (int)$result['YDS'], 
        (int)$result['TD'], 
        (int)$result['FUM'], 
        (int)$result['INT'], 
        (int)$result['LNG'], 
        (double)$result['QBR'], 
        (double)$result['RAT'],); 
} 
print_r($CMP); 
$CMP = json_encode($CMP); 
?>

而這正是被請求的JSON：

這是從另一個頁面，可以做從顯示結果的查詢回聲，但後續代碼var_dump（$康恩）返回對象（mysqli的）＃1（0）{}：

$query = "SELECT * FROM arodgers WHERE season =(SELECT max(season) FROM arodgers)"; 
$result = $conn->query($query); 
if(!$result) die('Database access failed: ' . $conn->error); 
    $rows = $result->fetch_array(MYSQLI_BOTH); 
echo <<<_END 
    <p>Season: $rows[SEASON]<br /> 
    Completions: $rows[CMP] <br /> 
    Attempts: $rows[ATT] <br /> 
    Yards: $rows[YDS] <br /> 
    Completion%: $rows[CMP] <br /> 
    Touchdowns: $rows[TD] </p> 

_END;
