Know exactly what changed in PHP data and text.

Added, removed, modified and moved values at their exact paths, records matched by ID, redacted secrets, and GitHub-style line diffs.

Installation

composer require pharaonic/php-diff

Usage

Compare two values

use Pharaonic\Diff\Diff;

$before = ['name' => 'Ali', 'age' => 30, 'phone' => '0100'];
$after  = ['name' => 'Ali', 'age' => 31, 'email' => 'ali@example.com'];

$result = Diff::between($before, $after);

$result->wasModified('age');   // true
$result->wasAdded('email');    // true
$result->wasRemoved('phone');  // true
$result->hasChanged('name');   // false

Compare two texts

echo Diff::text("apple\nbanana\ncherry\n", "apple\nblueberry\ncherry\n")->toUnified();
