PHP包,用于将文件扩展名转换为MIME类型,反之亦然。

此包使用httpdmime.types文件生成文件扩展名到MIME类型的映射,反之亦然。

mime.types文件由bin/generate.php解析,并转换为在mime.types.php中的优化PHP数组,然后由辅助类\Mimey\MimeTypes包装。

使用方法

$mimes = new \Mimey\MimeTypes;

// Convert extension to MIME type:
$mimes->getMimeType('json'); // application/json

// Convert MIME type to extension:
$mimes->getExtension('application/json'); // json

获取所有

虽然很少见,但某些扩展名对应多个MIME类型

// Get all MIME types for an extension:
$mimes->getAllMimeTypes('wmz'); // array('application/x-ms-wmz', 'application/x-msmetafile')

然而,许多MIME类型对应多个扩展名

// Get all extensions for a MIME type:
$mimes->getAllExtensions('image/jpeg'); // array('jpeg', 'jpg', 'jpe')

自定义转换

您可以通过更改传递给MimeTypes的映射来添加自定义转换。

有一个MimeMappingBuilder可以帮助您完成此操作

// Create a builder using the built-in conversions as the basis.
$builder = \Mimey\MimeMappingBuilder::create();

// Add a conversion. This conversion will take precedence over existing ones.
$builder->add('custom/mime-type', 'myextension');

$mimes = new \Mimey\MimeTypes($builder->getMapping());
$mimes->getMimeType('myextension'); // custom/mime-type
$mimes->getExtension('custom/mime-type'); // myextension

您可以将任何数量的转换添加到构建器中

$builder->add('custom/mime-type', 'myextension');
$builder->add('foo/bar', 'foobar');
$builder->add('foo/bar', 'fbar');
$builder->add('baz/qux', 'qux');
$builder->add('cat/qux', 'qux');
...

优化自定义转换加载

您可以通过将所有转换保存为构建步骤的一部分的编译PHP文件来优化自定义转换的加载。

// Add a bunch of custom conversions.
$builder->add(...);
$builder->add(...);
$builder->add(...);
...
// Save the conversions to a cached file.
$builder->save($cache_file_path);

然后可以加载该文件以避免重复调用$builder->add(...)的开销

// Load the conversions from a cached file.
$builder = \Mimey\MimeMappingBuilder::load($cache_file_path);
$mimes = new \Mimey\MimeTypes($builder->getMapping());
