嗨有一个问题要解决，我正在尝试解决它很长时间..
这里是：
我得到了这个数组：
$arr = Array(
[0] => Array
(
[product_option_id] => 234
[product_option_value] => Array
(
[0] => Array
(
[product_option_value_id] => 30
[option_value_id] => 65
[option_name] => 1.2 mm
)
[1] => Array
(
[product_option_value_id] => 23
[option_value_id] => 50
[option_name] => 1.6 mm
)
)
[option_id] => 14
[name] => Thickness (mm)
[option_level] => 1
)
[1] => Array
(
[product_option_id] => 232
[product_option_value] => Array
(
[0] => Array
(
[product_option_value_id] => 19
[option_value_id] => 64
[option_name] => 22
)
[1] => Array
(
[product_option_value_id] => 24
[option_value_id] => 54
[option_name] => 12
)
[2] => Array
(
[product_option_value_id] => 25
[option_value_id] => 55
[option_name] => 14
)
[3] => Array
(
[product_option_value_id] => 26
[option_value_id] => 57
[option_name] => 16
)
[4] => Array
(
[product_option_value_id] => 27
[option_value_id] => 61
[option_name] => 19
)
[5] => Array
(
[product_option_value_id] => 29
[option_value_id] => 49
[option_name] => 10
)
)
[option_id] => 13
[name] => Length (mm)
[option_level] => 2
)
[2] => Array
(
[product_option_id] => 233
[product_option_value] => Array
(
[0] => Array
(
[product_option_value_id] => 20
[option_value_id] => 51
[option_name] => Black
)
[1] => Array
(
[product_option_value_id] => 22
[option_value_id] => 52
[option_name] => White
)
)
[option_id] => 15
[name] => Color
[option_level] => 3
)
);
我想做类似的事情：1级的所有选项必须具有2级的所有选项，2级的所有选项必须具有3级的所有选项，依此类推......
[level1 Option A]
[level2 Option B1]
[level 3 Option C1]
[level2 Option B2]
[level 3 Option C1]
[level1 Option B]
[level2 Option B1]
[level 3 Option C1]
[level2 Option B2]
[level 3 Option C1]
有人能帮助我吗？我坚持下去。
提前致谢
