php-diff

Highlight diffs provided by Sebastian Bergmann diff

Installation

composer.phar require sokil/php-diff

Useage

<?php

use Sokil\Diff\Change;
use Sokil\Diff\Renderer;

$diffRenderer = new Renderer();
$actualDiff = $diffRenderer->render(new Change(
    implode(PHP_EOL, ['line1', 'line2', 'line3']),
    implode(PHP_EOL, ['line1', 'line2changed', 'line3'])
));

Format of diff output

Format of diff tags may be configured. By default renders only two tags: <ins> and <del>. To highlight output, use predefined format:

<?php
$renderer = new Renderer([
    'format' => Renderer::FORMAT_COLOUR
]);

This will produce following HTML:

line1
<del style="background: #ffe7e7;">line2</del>
<ins style="background: #ddfade;">line2changed</ins>
line3

To fully customize style, use next syntax (this format has alias Renderer::FORMAT_COLOUR):

<?php
$renderer = new Renderer([
    'format' => [
        'insert' => [
            'tag' => 'ins',
            'attributes' => 'style="background: #ddfade;"',
        ],
        'delete' => [
            'tag' => 'del',
            'attributes' => 'style="background: #ffe7e7;"',
        ]
    ]
]);

// this is same to
$renderer = new Renderer([
    'format' => Renderer::FORMAT_COLOUR
]);

Default format Renderer::FORMAT_DEFAULT has following notation:

<?php
$renderer = new Renderer([
    'insert' => [
        'tag' => 'ins',
    ],
    'delete' => [
        'tag' => 'del',
    ]
]);

// this is same to
$renderer = new Renderer([
    'format' => Renderer::FORMAT_DEFAULT
]);
