PHP查找匹配文件名的文件扩展名

Question

Let say I have image.jpg on my directory.

And assume that the only detail I know is that I have a filename which name = 'image' but i don't know what it's extension.

Is there a PHP function to know the extension of the file?

Answer 1

您可以使用glob查找文件：

$matching = glob('/some/directory/' . $name . '.*');
