**TailwindMerge for PHP** allows you to merge multiple [Tailwind CSS](https://tailwindcss.com/) classes and automatically resolves conflicts between classes by removing classes conflicting with a class defined later.

A PHP port of [tailwind-merge](https://github.com/dcastil/tailwind-merge) by [dcastil](https://github.com/dcastil).

Supports Tailwind v3.0 up to v3.4.

Get Started
-----------

[](#get-started)

> **Requires [PHP 8.1+](https://php.net/releases/)**

First, install TailwindMerge via the [Composer](https://getcomposer.org/) package manager:

```
composer require gehrisandro/tailwind-merge-php
```

Then, use the `TailwindMerge` class to merge your Tailwind CSS classes:

```
use TailwindMerge\TailwindMerge;

$tw = TailwindMerge::instance();

$tw->merge('text-red-500', 'text-blue-500'); // 'text-blue-500'
```

You can adjust the configuration of `TailwindMerge` by using the factory to create a new instance:

```
use TailwindMerge\TailwindMerge;

$instance = TailwindMerge::factory()
    ->withConfiguration([
        'prefix' => 'tw-',
    ])->make();

$instance->merge('tw-text-red-500', 'tw-text-blue-500'); // 'tw-text-blue-500'
```

For more information on how to configure `TailwindMerge`, see the [Configuration](#configuration) section.

Usage
-----

[](#usage)

`TailwindMerge` is not only capable of resolving conflicts between basic Tailwind CSS classes, but also handles more complex scenarios:

```
use TailwindMerge\TailwindMerge;

$tw = TailwindMerge::instance();

// conflicting classes
$tw->merge('block inline'); // inline
$tw->merge('pl-4 px-6'); // px-6

// non-conflicting classes
$tw->merge('text-xl text-black'); // text-xl text-black

// with breakpoints
$tw->merge('h-10 lg:h-12 lg:h-20'); // h-10 lg:h-20

// dark mode
$tw->merge('text-black dark:text-white dark:text-gray-700'); // text-black dark:text-gray-700

// with hover, focus and other states
$tw->merge('hover:block hover:inline'); // hover:inline

// with the important modifier
$tw->merge('!font-medium !font-bold'); // !font-bold

// arbitrary values
$tw->merge('z-10 z-[999]'); // z-[999]

// arbitrary variants
$tw->merge('[&>*]:underline [&>*]:line-through'); // [&>*]:line-through

// non tailwind classes
$tw->merge('non-tailwind-class block inline'); // non-tailwind-class inline
```

It's possible to pass the classes as a string, an array or a combination of both:

```
$tw->merge('h-10 h-20'); // h-20
$tw->merge(['h-10', 'h-20']); // h-20
$tw->merge(['h-10', 'h-20'], 'h-30'); // h-30
$tw->merge(['h-10', 'h-20'], 'h-30', ['h-40']); // h-40
```

Cache
-----

[](#cache)

For a better performance, `TailwindMerge` can cache the results of the merge operation. To activate pass your cache instance to the `withCache` method.

It accepts any [PSR-16](https://www.php-fig.org/psr/psr-16/) compatible cache implementation.

```
TailwindMerge::factory()
  ->withCache($cache)
  ->make();
```

When you are making changes to the configuration make sure to clear the cache.

Configuration
-------------

[](#configuration)

If you are using Tailwind CSS without any extra config, you can use TailwindMerge right away. And stop reading here.

If you're using a custom Tailwind config, you may need to configure TailwindMerge as well to merge classes properly.

By default TailwindMerge is configured in a way that you can still use it if all the following apply to your Tailwind config:

- Only using color names which don't clash with other Tailwind class names
- Only deviating by number values from number-based Tailwind classes
- Only using font-family classes which don't clash with default font-weight classes
- Sticking to default Tailwind config for everything else

If some of these points don't apply to you, you need to customize the configuration.

This is an example to add a custom font size of "very-large":

```
TailwindMerge::factory()->withConfiguration([
        'classGroups' => [
            'font-size' => [
                ['text' => ['very-large']]
            ],
        ],
    ])->make();
```

For a more detailed explanation of the configuration options, visit the [original package documentation](https://github.com/dcastil/tailwind-merge/blob/v1.14.0/docs/configuration.md).
