Here's how to pretend that array_map supports passing keys in #php

$keys = array_keys($data);  
array_combine(  
 $keys,  
 array_map(  
 fn ($values, $key) => ... ,  
 $data,  
 $keys  
 )  
);  

Keys tend to be important in PHP because they are often strings that contain relevant data, rather than index offsets.

Dropping the array_combine would result in losing all of the keys from the resulting array & reverting to int offsets.
