Multiple Upload and Image names

Question

I have a multiple upload form, that renames images after upload:

for ($i = 0; $i < count($_FILES['images']['name']); $i++) {
$ext= end(explode(".",  $_FILES['images']['name'][$i]));
$name =  rand(1111111,9999999).'.'.$ext; 
}

With print_r($name) the output is a string image1.jpgimage2.jpgimage3.jpg. Why the output is a string? How can I give an array? Thanks in advance

Answer 1

$name[] = rand(1111111,9999999).'.'.$ext;

will do the trick

Bonus:

$ext = pathinfo($_FILES['images']['name'][$i], PATHINFO_EXTENSION);
