It allows you to get groups of one topic from the transferred set of sentences. For example, combine news headlines from different publications, as Google News does. Installation ------------ [](#installation) Run this at the command line: ``` $ composer require esplora/similar ``` Usage ----- [](#usage) We need to create an object by passing a closure function as an argument, which checks if two strings are similar: ``` use Esplora\Similar\Similar; $similar = new Similar(function (string $a, string $b) { similar_text($a, $b, $copy); return 51 < $copy; }); ``` > Note that you don't need to use `similar_text`. You can use other implementations like `soundex` or something else. Then we have to call the `findOut` method passing it a one-dimensional array with strings: ``` $similar->findOut([ 'Elon Musk gets mixed COVID-19 test results as SpaceX launches astronauts to the ISS', 'Elon Musk may have Covid-19, should quarantine during SpaceX astronaut launch Sunday', // Superfluous word 'Can Trump win with ‘fantasy’ electors bid? State GOP says no', ]); ``` As a result, there will be only one group containing headers: ``` 'Elon Musk gets mixed COVID-19 test results as SpaceX launches astronauts to the ISS', 'Elon Musk may have Covid-19, should quarantine during SpaceX astronaut launch Sunday', ``` Keys ---- [](#keys) The input array stores its keys so that you can do additional processing: ``` $similar->findOut([ 'kos' => "Trump acknowledges Biden's win in latest tweet", 'foo' => 'Elon Musk gets mixed COVID-19 test results as SpaceX launches astronauts to the ISS', 'baz' => 'Trump says Biden won but again refuses to concede', 'bar' => 'Elon Musk may have Covid-19, should quarantine during SpaceX astronaut launch Sunday', ]); ``` The result will be two groups: ``` [ 'foo' => 'Elon Musk gets mixed COVID-19 test results as SpaceX launches astronauts to the ISS', 'bar' => 'Elon Musk may have Covid-19, should quarantine during SpaceX astronaut launch Sunday', ], [ 'baz' => 'Trump says Biden won but again refuses to concede', 'kos' => "Trump acknowledges Biden's win in latest tweet", ], ``` Objects ------- [](#objects) It is also possible to pass objects to evaluate more complex conditions. Each passed object must be able to cast to a string via the `__toString()` method. ``` $similar->findOut([ new FixtureStingObject('Lorem ipsum dolor sit amet, consectetur adipiscing elit.'), ]); ``` License ------- [](#license) The MIT License (MIT).
