我有以下常见问题，但无法确定哪种数组函数可能适用于以下格式：

((已尝试array_merge，array_merge_recursive，array_combine，array_splice，但未按预期工作。)Array

(

[0] => Array

(

[r_id] => 11

[r_sid] => RC

[d_id] => 2

)

[1] => Array

(

[r_id] => 7

[r_sid] => RC

[c_id] => 51

)

[2] => Array

(

[r_id] => 6

[r_sid] => JN

[c_id] => 52

)

[3] => Array

(

[r_id] => 7

[r_sid] => JN

[c_id] => 51

)

[4] => Array

(

[r_id] => 7

[r_sid] => LG

[c_id] => 51

)

[5] => Array

(

[r_id] => 7

[r_sid] => BN

[c_id] => 51

)

[6] => Array

(

[r_id] => 6

[r_sid] => IVS

[c_id] => 52

)

[7] => Array

(

[r_id] => 7

[r_sid] => IVS

[c_id] => 51

)

)

现在，我需要通过通用的r_sid和c_id键合并此数组值；唯一特殊的情况是，如果有d_id键而不是c_id，则我们将其与数组中具有相似r_sid的任何值合并/合并。

如果更容易理解，则最终解决方案应如下所示：Array

(

[0] => Array

(

[r_id] => 11,7

[r_sid] => RC

[d_id] => 2

[c_id] => 51

)

[1] => Array

(

[r_id] => 6,7

[r_sid] => JN, IVS

[c_id] => 52,51

)

)

与任何人都不匹配的r_sid值都应该被丢弃。

感谢您的帮助。非常感谢！
