  ["instantiator":"Doctrine\ORM\Mapping\ClassMetadataInfo":private]=>
  object(Doctrine\Instantiator\Instantiator)#2989 (0) {

这是我的数组$fields：

array(5) {
  [0]=>
  object(App\Entity\Fields)#5481 (4) {
    ["id":"App\Entity\Fields":private]=>
    int(1)
    ["field_name":"App\Entity\Fields":private]=>
    string(2) "id"
    ["field_type":"App\Entity\Fields":private]=>
    string(6) "hidden"
    ["field_options":"App\Entity\Fields":private]=>
    string(0) ""
  }
  [1]=>
  object(App\Entity\Fields)#5485 (4) {
    ["id":"App\Entity\Fields":private]=>
    int(2)
    ["field_name":"App\Entity\Fields":private]=>
    string(8) "password"
    ["field_type":"App\Entity\Fields":private]=>
    string(8) "password"
    ["field_options":"App\Entity\Fields":private]=>
    string(0) ""
  }
  [2]=>
  object(App\Entity\Fields)#5486 (4) {
    ["id":"App\Entity\Fields":private]=>
    int(3)
    ["field_name":"App\Entity\Fields":private]=>
    string(4) "role"
    ["field_type":"App\Entity\Fields":private]=>
    string(8) "dropdown"
    ["field_options":"App\Entity\Fields":private]=>
    string(12) "admin,member"
  }
  [3]=>
  object(App\Entity\Fields)#5487 (4) {
    ["id":"App\Entity\Fields":private]=>
    int(4)
    ["field_name":"App\Entity\Fields":private]=>
    string(5) "email"
    ["field_type":"App\Entity\Fields":private]=>
    string(5) "email"
    ["field_options":"App\Entity\Fields":private]=>
    string(0) ""
  }
  [4]=>
  object(App\Entity\Fields)#5488 (4) {
    ["id":"App\Entity\Fields":private]=>
    int(5)
    ["field_name":"App\Entity\Fields":private]=>
    string(9) "is_active"
    ["field_type":"App\Entity\Fields":private]=>
    string(6) "hidden"
    ["field_options":"App\Entity\Fields":private]=>
    string(0) ""
  }
}

我要做的是将field_type的{{1}}值合并到$fields的{{1}}中。

所以在fieldMappings中，这是我要达到的最终结果：

$classes

这是我的方法：

$classes

我的错误消息是

未定义索引：field_name

Answer 1

您已经忘记了$ fields是一个数组，并且您尝试访问的索引不会在该数组的索引级别退出，除非将其设置为索引级别..我认为这种方法应该可以解决问题

foreach ($classes->fieldMappings as $fieldMapping) {
foreach($fields as $field ) 
{  if($fieldMapping['fieldName']==$field['field_name']) 
  {
   $fields.push($field['field_type']); 
  }
 }
}

如何将数据从数组推入对象？
