MySQL returns only the first character of the fields, but works fine on the local

Question

I don't know what exactly is happening, but only the first character is returned for all my columns when I loaded my site. It works fine on the local machine.

I found a similar question here, but I could not find the answer:
https://stackoverflow.com/questions/10507848/mysql-query-returns-only-the-first-letter-of-strings-only-when-page-is -viewed-on

    // Log Table Query
    unset($stmt);
    $stmt = $db->stmt_init();
    $stmt = $db->prepare( "SELECT * FROM logs ORDER BY `id` DESC" );

    $stmt->store_result();
    $stmt->bind_result($r_id, $r_time, $r_logger, $r_message, $r_category);
    $stmt->execute();

    while( $stmt->fetch() )
    {
        var_dump($r_message);
        var_dump($r_category);
    }

    $stmt->close();

This outputs to localhost for example:

string (5) String "Hello" (3) "Cow"

But on a real server:

string (1) String "H" (1) "C"

Any ideas?

Edit

I think this only applies to string types. Integer types are returned:

Int (2893)

, localhost ( ). :

1. store_result() execute(). http://php.net/manual/en/mysqli-stmt.store-result.php execute() .

, :

    /* unsetting doesn't matter you're
    going to overwrite it anyway */
    unset($stmt);

    /* you dont need to initialize $stmt with $db->stmt_init(),
    $db->prepare() method will create it for you */
    $stmt = $db->stmt_init();
    $stmt = $db->prepare("SELECT * FROM logs ORDER BY `id` DESC");

    /* execute the query first before storing
    the result and binding it your variables */
    if (!$stmt->execute()) {
        echo "query execution error";
        exit();
    }

    /* store the result */
    $stmt->store_result();

    /* then bind your variables */
    $stmt->bind_result($r_id, $r_time, $r_logger, $r_message, $r_category);

    /* fetch data and display */
    while($stmt->fetch()) {
        var_dump($r_message);
        var_dump($r_category);
    }

    $stmt->close();

, . , , , WHERE first_name LIKE <input here>:

    $result = $db->query("SELECT * FROM logs ORDER BY `id` DESC");

    if ($result === false) {
        echo "query execution error";
        exit();
    }

    /* You can use either MYSQLI_NUM or MYSQLI_ASSOC os MYSQLI_BOTH
    see php.net for more info */
    echo "<pre>";
    while($line = $result->fetch_array(MYSQLI_NUM)) {
        print_r($line);
        echo "\n";
    }
    echo "</pre>";

Answer 2

, unset($stmt) $stmt = db->stmt_init() free_result()

// Log Table Query
$stmt->free_result(); //Free old results first
$stmt = $db->prepare( "SELECT * FROM logs ORDER BY `id` DESC" );

$stmt->store_result();
$stmt->bind_result($r_id, $r_time, $r_logger, $r_message, $r_category);
$stmt->execute();

while( $stmt->fetch() )
{
    var_dump($r_message);
    var_dump($r_category);
}

$stmt->close();
