How to create such an array

How to create such an array and write the corresponding small category equal to the big category ID to subCats
Array (
Id => "$ Xhref .....",
Name => "$ Xtext ....",
)

$ Dafenleishu = count ($ Dhref );
$ Xiaofenleishu = count ($ Xhref );

For ($ x = 1; $ x <= $ dafenleishu-1; $ x ++ ){
$ Cats [] = array (
Id => "$ Dhref [$ x]",
Name => "$ Dtext [$ x]",
SubCats => array ()
);

}


$ Dhref // Big Classification ID

$ Dtext // Big classification name

$ Xhref // small category ID

$ XID_D // The ID of a small-Category pair.

$ Xtext // small category name


Output

This does not seem to work out.

Thank you for continuing to learn. I feel that is what I need. if I try my best to solve the problem by myself, I will continue to learn the main purpose.
