问题描述
我已经在PHP文档中浏览了一段时间,但是我找不到将MIME类型扩展名转换为文件类型扩展名的方法.
I've been looking around in the PHP documentation for some time, but I found no way to convert a MIME type extension to a file type extension.
image_type_to_extension
如果文件是图像,则似乎可以使用.在我的特定情况下,mime类型不适用于图像,它们适用于字体类型:"otf,ttf".
Seems to work if the file is an image. In my particular case, the mime types are not for images, they are for font types: 'otf, ttf'.
推荐答案
您可以使用类似的东西:
You could use something like:
function getExtension ($mime_type){
$extensions = array('image/jpeg' => 'jpeg',
'text/xml' => 'xml'
);
// Add as many other Mime Types / File Extensions as you like
return $extensions[$mime_type];
}
注意:并非每种MIME类型都有固定的文件扩展名.另外,诸如application/octet-stream
之类的MIME类型可以引用多个文件扩展名.
Note: not every MIME type has a fixed file extension. Also, MIME types like application/octet-stream
can refer to multiple file extensions.
