Tries
Explore the trie data structure as used in PHP to store and search string-indexed sets. Understand how tries support map-like operations with persistence and order. Learn to implement tries for use cases such as autocomplete and predictive text, and see functional programming concepts like composition and partial application applied in PHP.

Trie data structure in PHP
Tries are persistent and ordered tree structures with an empty root node capable of storing string-indexed sets, similar to hash tables and maps. They’re made up of nodes that store partial set keys, dispersed across the entire structure. Because tries can be used to store key-value pairs, they can be used in place of the standard PHP array.
The trie pictured below has the i, ...
