php - 如何通过继续键的增量将关联附加到另一个关联数组中？

Question

我有以下关联数组：

0 => 
    array (size=2)
      'id' => string '0000' (length=4)
      'polling_id' => string '0' (length=1)
1 => 
    array (size=2)
      'id' => string '0001' (length=4)
      'polling_id' => string '1' (length=1)

我有第二个关联数组：

0 => 
    array (size=3)
      'id' => string '0002' (length=4)
      'polling_id' => string '0' (length=1)
      'backup_id' => string '4500' (length=4)
1 => 
    array (size=3)
      'id' => string '0003' (length=4)
      'polling_id' => string '0' (length=1)
      'backup_id' => string '4500' (length=4)

我希望它看起来像：

0 => 
    array (size=2)
      'id' => string '0000' (length=4)
      'polling_id' => string '0' (length=1)
1 => 
    array (size=2)
      'id' => string '0001' (length=4)
      'polling_id' => string '1' (length=1)
2 => 
    array (size=3)
      'id' => string '0002' (length=4)
      'polling_id' => string '0' (length=1)
      'backup_id' => string '4500' (length=4)
3 => 
    array (size=3)
      'id' => string '0003' (length=4)
      'polling_id' => string '0' (length=1)
      'backup_id' => string '4500' (length=4)

我怎样才能做到这一点？

尝试 array_merge($a1,$a2)合并这两个数组。
