mysqli query not returning results with JSON and Google Charts
Question
I developed locally and everything worked fine. When I uploaded to the host, some database information is failing to show.
This is aRodgersForm.php where query is made:
<?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);
?>
And this is where the json is requested:

This is a query from another page that does display results from the echo, but the var_dump($conn) returns object(mysqli)#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;
Live Page So if you look at the stats of the players on the home page the results are all shown, but if you click on the full stats page it is blank. The only results that are not showing are the ones I get with JSON for Google Charts.

It seems it was a problem with an older version of PHP the free host was using. I moved to a different host with updated php and the website works fine. I developed in 5.6 and the host had 5.2.
