How to change name of uploaded file without changing extension

Question

i'd like to change the name of uploaded file to md5(file_name).ext, where ext is extension of uploaded file. Is there any function which can help me to do it?

Answer 1

$filename  = basename($_FILES['file']['name']);
$extension = pathinfo($filename, PATHINFO_EXTENSION);
$new       = md5($filename).'.'.$extension;

if (move_uploaded_file($_FILES['file']['tmp_name'], "/path/{$new}")) 
{
   // other code
}
