谁知道为什么没数据,但是还是返回获取成功。而空数组不是false吗?

$result = BookCode::where('book_name','s121212ss')->get();
if ($result) {
 return [
 'd' => $result,
 'c' => 200000,
 'm' => '获取成功',
 ];} else {
 return [
 'c' => 400000,
 'm' => '',
 'd' => $result,
 ];}

因为返回的是一个 Collection,是一个非空对象

if ($result->isNotEmpty()) {
    // ok
} else {
    // false
}
