In the previous series, we introduced sequential lookups based on unordered lists, binary lookups based on ordered arrays, balanced lookup trees, and red-black trees, which are their time complexity on average and worst-case scenarios:It can be seen

The most frequently used data types in PHP are non-strings and arrays, and PHP is easier to get started with because of the very flexible array types. It is necessary to introduce a hash table (HashTable) before you begin to describe these data
