README
A PHP implementation of the Trie, RadixTrie and SuffixTrie data structures
Requirements
- PHP version 7.2 or higher
Installation
We recommend installing this package with Composer.
Via composer
In your project root folder, execute
composer require markbaker/tries:dev-master
You should now have the files composer.json
and composer.lock
as well as the directory vendor
in your project directory.
You can then require the Composer autoloader from your code
require 'vendor/autoload.php';
Or, if you already have a composer.json file, then require this package in that file
"require": {
"markbaker/tries": "dev-master"
}
and update composer.
composer update
From Phar
Although we strongly recommend using Composer, we also provide a Phar archive builder that will create a Phar file containing all of the library code.
The phar builder script is in the repository root folder, and can be run using
php buildPhar.php
To use the archive, just require it from your script:
require 'Tries.phar';
Standard Autoloader
If you want to run the code without using composer's autoloader, and don't want to build the phar, then required the bootstrap.php
file from the repository in your code, and this will enable the autoloader for the library.
require 'bootstrap.php';

Examples
The /examples folder has two examples to demonstrate their use:
-
playerSearch.php
-
playerSearchRadixTrie.php
-
playerSearchSuffixTrie.php
allows a search on Wigan Warriors rugby league players based on surname, displaying the record of those that match the entered search criteria
usage:
php playerSearch <name> <limit>
or
php playerSearchRadixTrie <name> <limit>
or
php playerSearchSuffixTrie <name> <limit>
where
name the first few characters of the surname you want to search for (or characters from anywhere in the name if using the Suffix Trie search) limit optional (default 8) limits the number of results returned
-
wordSearch.php
-
wordSearchRadixTrie.php
searches an English dictionary for words, displaying those that match the entered search criteria
usage:
php wordSearch <searchterm> <limit>
or
php wordSearchRadixTrie <searchterm> <limit>
where
searchterm can be a prefix* e.g. "aba*" will return words beginning with "aba" a *suffix e.g. "*ose" will return words ending in "ose" or a split*search criteria e.g. "t*ly" will return words beginning with "t" and ending in "ly" limit optional (default 8) limits the number of results returned
Note that the dictionary of 160k words will take some time to load, depending on your system
