我有两个阵列，它们具有一个相同的键值对。我想将两个具有相同键值对的数组和其余数组元素组合为多维数组。
以下是数组
阵列1

需要的新数组，其字段值（读取到事务编号的日期）来自相同序列号的第二个数组，作为新数组中的单独数组。该数组中的多维数组。

您可以使用array_merge() 函数

这是猜测......
将array2嵌入array1'children'索引......
// index array 1 by sequence_number
$array1 = array_combine( array_column( $array1, 'sequence_number' ), $array1 );
foreach( $array2 as $two )
{
if( !isset( $array1[ $two['sequence_number'] ]['children'] ) )
{
$array1[ $two['sequence_number'] ]['children'] = array();
}
$array1[ $two['sequence_number'] ]['children'][] = $two;
}
