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?
您可以使用glob
查找文件:
$matching = glob('/some/directory/' . $name . '.*');
http://php.net/manual/zh/function.pathinfo.php显示了您需要的所有内容,路径,文件名和扩展名。
