我要找的是一个可以接受任何文件扩展名并返回该扩展名描述的东西

例如：

$extension = 'PNG';
$description = ext_description($extension);

echo $description // Outputs 'Portable Network Graphic'
或

我搜索了谷歌，但什么也没找到。如果有人知道这样一个脚本是否存在，这将大大节省时间

提前谢谢。

是的，有，一个是

由于对每个人的描述都是另外一回事，因此可以创建一个简单的查找函数，用于处理数组数据。只需将文件类型添加到阵列中，即可完成以下操作：

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,但你可以创建一个

function ext_description($extension) {
    switch ($extension) {
    case "png":
        return "Portable Network Graphic";
    case "doc":
        return "Microsoft Office Word Document";
    default:
        return "Unknow extention";
}
您可以在这里找到所有现有扩展的完整列表：）

不，在PHP中没有简单的方法可以做到这一点。最接近的替代方案是MIME类型，您可以使用
finfo
或
MIME\u content\u type
获得该类型

如果您在windows上运行，还可以使用
SHGetFileInfo
函数，该函数正好满足您的需要

您可以使用文件的mime类型

您可以使用文件的mime类型

我正在查看，但是，我发现它只返回mime类型，而不是文件扩展名的描述。例如，对于gif图像，它将返回'image/gif'，而不是'Graphic Interchange Format'。这里是许多已知mime类型的列表：但是描述不同，因此您可以根据自己的需要构建它，将添加一些小代码。不过，我正在研究这个问题，我发现它只返回mime_类型，而不是文件扩展名的描述。例如，对于gif图像，它将返回'image/gif'，而不是'Graphic Interchange Format'。这里是许多已知mime类型的列表：但是描述不同，因此您可以根据自己的需要构建它，将添加一些小代码。我想这可能是我必须要做的。我会在这里张贴一个代码链接，当我为任何人谁是在寻找这个too我想这可能是我必须做的。我会张贴一个链接到代码在这里，当我完成了任何人谁是寻找这个太
