这是我在控制器中的getIndex（）函数中的内容
public function getIndex() {
$categories = Category::all();
foreach ($categories as $category) {
$categories[$category->id] = $category->name;
}
......
}
因此，我希望从循环中获取所有类别名称。
但是，例如，如果我想通过在视图中执行此操作来获得结果
@foreach ($categories as $name)
<ul>
<li>{{var_dump($name)}}</li>
</ul>
@endforeach
结果就像
object（Category）＃169（20）{[“” fillable“：protected] => array（1）{[0] => string（4）” name“} [” connection“：protected] => NULL [” table “：protected] => NULL [” primaryKey“：protected] => string（2）” id“ [” perPage“：protected] => int（15）[” incrementing“] => bool（true）[” timestamps “] => bool（true）[”属性“：受保护] => array（4）{[”“ id”] => string（1）“ 1” [“ name”] => string（3）“ foo1” [“ created_at”] =>字符串（19）“ 2014-11-08 14:29:30” [“ updated_at”] =>字符串（19）“ 2014-11-08 14:29:30”} [“原始“：protected] => array（4）{[”“ id”] => string（1）“ 1” [“ name”] => string（3）“ foo1” [“ created_at”] =>字符串（19）“ 2014-11-08 14:29:30” [“ updated_at”] =>字符串（19）“ 2014-11-08 14:29:30”} [“关系”：受保护] =>数组（0）{} [“隐藏”：受保护] =>数组（0）{} [“可见”：受保护] =>数组（0）{} [“追加”：受保护] =>数组（0 ）{} [“ guarded”：保护] => array（1）{[0] => string（1）“ *”} [“ dates”：protected] => array（0）{} [“ touches”： protected] => array（0）{} [“ observables”：protected] => array（0）{} [“ with”：protected] => array（0）{} [“ morphClass”：protected] => NULL [“ exists”] => bool（true）}array（0）{} [“ hidden”：protected] => array（0）{} [“ visible”：protected] => array（0）{} [“ appends：protected] => array（0）{ } [“ guarded”：protected] => array（1）{[0] => string（1）“ *”} [“ dates”：protected] => array（0）{} [“ touches”：protected] => array（0）{} [“ observables”：受保护] => array（0）{} [“ with”：protected] => array（0）{} [“ morphClass”：protected] => NULL [“存在“] => bool（true）}array（0）{} [“ hidden”：protected] => array（0）{} [“ visible”：protected] => array（0）{} [“ appends：protected] => array（0）{ } [“ guarded”：受保护] => array（1）{[0] =>字符串（1）“ *”} [“ dates”：受保护] => array（0）{} [“ touches”：protected] => array（0）{} [“ observables”：受保护] => array（0）{} [“ with”：protected] => array（0）{} [“ morphClass”：protected] => NULL [“存在“] => bool（true）}array（0）{} [“ observables”：protected] => array（0）{} [“ with”：protected] => array（0）{} [“ morphClass”：protected] => NULL [“ exists” ] => bool（true）}array（0）{} [“ observables”：protected] => array（0）{} [“ with”：protected] => array（0）{} [“ morphClass”：protected] => NULL [“ exists” ] => bool（true）}
字符串（3）“ foo1”
第一个结果来自何处，我如何摆脱它？谢谢！
您可以尝试以下方法：
// Get an associative array
$categories = Category::lists('name', 'id');
然后将其传递给视图进行循环：
<ul>
@foreach ($categories as $id => $name)
<li>{{$name}}</li>
@endforeach
</ul>
