php explode文件扩展名为null

Question

So, when I upload files, i want to check which file extension it is:

$files      = $_FILES['files'];

$files_name      =  $files['name'];     

Shows: `"img.jpg"'

$files_name_explode = end(explode('.', $files_name));

Getting null.

What am I doing wrong?

Thanks

Use below code :

$path = $_FILES['files']['name'];
$ext = pathinfo($path, PATHINFO_EXTENSION);

Hope it will help you :)
