PHP array foreach $ key ranking

{Code ...} above, I would like to ask if $ key is shaved to be removed, and the sorting is still normal. Example 1, James 2, Tom 3, Tom 4, and Tom red are normal sorting, but I want to shave off the data of the name and the data will become 1, James 3, Tom 4, and so on, but what I want is...

Foreach ($ abc as $ key => $ val) {Here we sort by $ key, but there are several people with the $ val condition in the middle who want to shave from the ranking}

Above, I would like to ask $ key if it is shaved to be removed, it will still be sorted normally

For example

1, Xiao Ming 2, Xiao Bai 3, Xiao Hei 4, Xiao Hong

This is a normal sorting, but I want to shave off the data with name =, and then it will become

1, Xiao Ming 3, Xiao Hei 4, Xiao Hong

But what I want is

1, Xiao Ming 2, Xiao Hei 3, Xiao Hong

Sort normally after Removal
