PHP library to get MIME types from extensions.

The original concept of my project, linking a single mimetype to a file extension, has been found to be insufficient in accurately reflecting the many-to-one relationships that exist in real-world use-cases. In practice, multiple file extensions often correspond to a single mimetype, rendering my existing design approach suboptimal.

Given these insights, I've decided to archive this repository. I recommend those interested to look at the approach taken by the repository patrickmccallum/mimetype-io. This project adopts a more nuanced perspective, effectively managing mimetypes by acknowledging the possibility of multiple extensions corresponding to a single mimetype. I believe this is a more promising approach for managing mimetypes moving forward.

Requirements

• Operating System: Linux | Windows.

• PHP versions: 8.0 | 8.1 | 8.2.

Installation

The preferred way to install this extension is through Composer.

To install PHP MimeType library, simply:

composer require josantonius/mime-type

The previous command will only install the necessary files, if you prefer to download the entire source code you can use:

composer require josantonius/mime-type --prefer-source

You can also clone the complete repository with Git:

git clone https://github.com/josantonius/php-mime-type.git

Available Classes

MimeType

Josantonius\MimeType\MimeType

Get array with all MIME types:

public function all(): array;

Get file extension from MIME type:

public function getExtension(string $mimeType): string|null;

Get MIME type from file extension:

public function getMime(string $extension): string|null;

MimeTypeCollection

Josantonius\MimeType\MimeTypeCollection

Get array with all MIME types:

public static function all(): array;

Get file extension from MIME type:

public static function getExtension(string $mimeType): string|null;

Get MIME type from file extension:

public static function getMime(string $extension): string|null;

Usage

Example of use for this library:

Get array with all MIME types

use Josantonius\MimeType\MimeType;

$mimeType = new MimeType();

$mimeType->all();

use Josantonius\MimeType\MimeTypeCollection;

MimeTypeCollection::all();

Result:

[
    [".123"]=> "application/vnd.lotus-1-2-3"
    [".3dml"]=> "text/vnd.in3d.3dml"
    [".3g2"]=> "video/3gpp2"
    [".3gp"]=> "video/3gpp"
    [".7z"]=> "application/x-7z-compressed"
    [".aab"]=> "application/x-authorware-bin"
    [".aac"]=> "audio/x-aac"
    [".aam"]=> "application/x-authorware-map"
    [".aas"]=> "application/x-authorware-seg"
    [".abw"]=> "application/x-abiword"
    (...)
]

Get file extension from MIME type

use Josantonius\MimeType\MimeType;

$mimeType = new MimeType();

$mimeType->getExtension('text/html'); // .html

use Josantonius\MimeType\MimeTypeCollection;

MimeTypeCollection::getExtension('application/zip'); // .zip

Get MIME type from file extension

use Josantonius\MimeType\MimeType;

$mimeType = new MimeType();

$mimeType->getMime('.tar'); // application/x-tar

// The dot can be omitted:

$mimeType->getMime('mp4'); // video/mp4

use Josantonius\MimeType\MimeTypeCollection;

MimeTypeCollection::getMime('.json'); // application/json
