尝试读取bool上的属性“name”

Question

我有一个问题Laravel 8和我不知道如何识别错误。

发生了以下情况。。

在我的控制器中，它如下所示：

$var  =  model::where('name', $name)->firstOrFail();
print_r($var)

Print_r把这个还给我

App\Models\test Object ( 
    [table:protected] => tb_test 
    [timestamps] => 
    [connection:protected] => mysql 
    [primaryKey:protected] => id 
    [keyType:protected] => int 
    [incrementing] => 1 
    [with:protected] => Array ( ) 
    [withCount:protected] => Array ( ) 
    [perPage:protected] => 15 
    [exists] => 1 
    [wasRecentlyCreated] => 
    [attributes:protected] => Array ( 
            [id] => 48494980 
            [name] => TEST
    ) 
    [original:protected] => Array ( 
            [id] => 48494980 
            [name] => TEST 
    ) 
    [changes:protected] => Array ( ) 
    [casts:protected] => Array ( ) 
    [classCastCache:protected] => Array ( ) 
    [dates:protected] => Array ( ) 
    [dateFormat:protected] => 
    [appends:protected] => Array ( ) 
    [dispatchesEvents:protected] => Array ( ) 
    [observables:protected] => Array ( ) 
    [relations:protected] => Array ( ) 
    [touches:protected] => Array ( ) 
    [hidden:protected] => Array ( ) 
    [visible:protected] => Array ( ) 
    [fillable:protected] => Array ( ) 
    [guarded:protected] => Array ( [0] => * ) 
    ) 

当我尝试使用foreach时，它返回我尝试读取bool上的属性“name”

有人能告诉我我做错了什么吗？

如果要一次遍历一个属性，请使用toArray（）

$var  =  model::where('name', $name)->firstOrFail();
$arrayVar = $var->toArray();

foreach( $arrayVar as $name => value) {
    //....
}
