Why Text diff by Horde?

Is the best lib for text diff in php. Is wise and experienced.

Advantages over analogues:

• diff by word inner each line
• diff by symbols inner each line
• tuning the output format
• the best speed in php
• the bets memory optimization in php

Optimiztions

For very long strings, there is a trick: divide long strings before use diff

Examples

use Topvisor\Horde\Text\Diff;

$diff = Diff\Diff::fromFileLineArrays($linesA, $linesB);

// calc diff as word
$renderer = new Diff\InlineRenderer();
$res = $renderer->render($diff);
var_dump($res);

// calc diff as symbol
$renderer = new Topvisor\Horde\Text\Diff\InlineRenderer(['split_characters' => true]);
$res2 = $renderer->render($diff);
var_dump($res2);
