Well, I'm just trying the following for around two hours now and I can't get it to work. The following code will always return "0". Please, can anyone see where is the problem. This should work as a charm. And in PhpMyAdmin, when I run the statement it works correctly.
Actually, this is a copy/pasted code from another question here on SO which was accepted as a working answer. Check it out here.
EDIT:
No errors are thrown using:
error_reporting(-1); and
PDO::ERRMODE_EXCEPTION.
UPDATE:
Definitely, I'm getting only the first row from the query where the Data_lenght is "0". I've tested also fetchAll, and also trying to access the Data_length index while fetching. No luck.
<!DOCTYPE html>
<head>
<title></title>
</head>
<body>
<?php
try {
error_reporting(-1);
$host_name = "my_hsot";
$database = "my_db";
$user_name = "my_user";
$password = "my_pwd";
$conn = new PDO("mysql:host=$host_name;dbname=$database", $user_name, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sth = $conn->query('SHOW TABLE STATUS');
$dbSize = 0;
$row = $sth->fetch(PDO::FETCH_ASSOC);
$dbSize = $row["Data_length"];
$decimals = 2;
$mbytes = round($dbSize/(1024*1024),$decimals);
echo $dbSize . "
" . $row["Data_length"];
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
?>
</body>
</html>
Any help is appreciated.
