我正在寻找的东西将采用任何文件扩展名并返回该扩展名的描述。
例如：
$extension = 'PNG';
$description = ext_description($extension);
echo $description // Outputs 'Portable Network Graphic'
OR
$extension = 'DOC';
$description = ext_description($extension);
echo $description // Outputs 'Microsoft Office Word Document'
我搜索了谷歌并没有出现任何问题。如果有人知道这样的剧本是否存在，那将节省大量时间。
提前致谢。

是的，有一个是getID3 Library and there is the PHP build in fileinfo library。
由于每个人的描述都是别的，您可以创建一个适用于数组数据的简单查找功能。您只需要将文件类型添加到数组中即可完成：
function ext_description($extension) {
static extensions = array(
'png' => 'Portable Network Graphic',
'doc' => 'Microsoft Office Word Document'
);
$extension = strtolower($extension);
return isset($extensions[$extension])
? $extensions[$extension]
: sprintf('Unknown File (%s)', $extension)
;
}

它不存在，但您可以创建一个。
function ext_description($extension) {
switch ($extension) {
case "png":
return "Portable Network Graphic";
case "doc":
return "Microsoft Office Word Document";
default:
return "Unknow extention";
}
您可以在此处找到所有现有扩展程序的完整列表：http://en.wikipedia.org/wiki/List_of_file_formats_(alphabetical）

不，在PHP中没有简单的方法可以做到这一点。最接近的替代方法是使用finfo或mime_content_type可以获得的MIME类型。
如果您在Windows上运行，您还可以使用SHGetFileInfo功能，它正是您正在寻找的功能。
