php mysqli获取数据显示数组结果但无法回显（显示NULL）

so my script i have done and using var_dump is showing results but when i do var_dump $row['blah']; its showing as NULL even though i can see its not when i var_dump($row) - i want to echo $customer_name for example but they show as nothing and not sure why.

Any ideas?

OUTPUT:

as you assign data to $row it means $result is nothing;

$row = mysqli_fetch_assoc($result); var_dump($result); // mysqli select query if($result) {
