I'm trying to get connect to my data base and having issues with it all.

Im getting this error on my while statement while($row = mysqli_fetch_array($result))

How do I fix that?

and this error on line 56

Fatal error: Call to a member function close() on a non-object
$result->close();

$mysqli = new mysqli("hostedresource.com", "UserName", "pass", "database");


if ($mysqli->connect_errno) {
printf("Connect failed: %s\n", $mysqli->connect_error);
exit();
}
 if ($result = $mysqli->query("SELECT * FROM AllGallerys order by RAND() limit 200'")) {
}


echo '';  
$count = 0;  
$rowCount = 0; 
while($row = mysqli_fetch_array($result))  
{  
$count++; 
$rowCount++; 

echo "";  
if($count%8===0) 

{ 
    echo ''; 

    if($rowCount%5===0) 
    { 
        echo '

'; 
        $rowCount = 0; 
    } 
   } 
} 

echo ' ';  

 $result->close();
 $mysqli->close();

Answer

You have a typo in your sql statement:

"SELECT * FROM AllGallerys order by RAND() limit 200'"
                                                    ^ here

Apart from that the construction is a bit strange, you should at least add an else section in case the query fails.
