I wrote this short script to upload multiple files, based on an old topic from Stackoverflow : How do you loop through $_FILES array?
(I didn't reply into it as it's 7 years old... Let me know if I did wrong)

if(!empty($_FILES)) {

    $i = 0;

    foreach($_FILES['images']['tmp_name'] as $index => $tmpName) {

        if(!empty($tmpName) && is_uploaded_file($tmpName)) {

            $img_url = url_rewrite($intitule).'-' . time() . $i . '.'.strtolower(substr(strrchr($tmpName, '.'),1));

            $gallery = $gallery . '|' . $img_url;

            move_uploaded_file( $tmpName, $dir_upload . '/' . $img_url);

        }

        $i++;

    }

 }

 echo $gallery;

So basically, I'm sending multiple files in $_FILES['images'] and I create unique names before upload (using time() + $i). I never get the file extension as $_FILES['images']['name'] seems to be empty. It's not though as Var_dump returns a complete array with everything I need :

array(1) {

  ["images"]=> array(5) { 

    ["name"]=> array(5) { 

      [0]=> string(13) "my-file-1.jpg" 

      [1]=> string(13) "my-file-2.jpg" 

      [2]=> string(13) "my-file-3.jpg" 

      [3]=> string(13) "my-file-4.jpg" 

      [4]=> string(13) "my-file-5.jpg" 

    }

    ["type"]=> array(5) { 

      [0]=> string(10) "image/jpeg" 

      [1]=> string(10) "image/jpeg" 

      [2]=> string(10) "image/jpeg" 

      [3]=> string(10) "image/jpeg" 

      [4]=> string(10) "image/jpeg" 

    }

    ["tmp_name"]=> array(5) { 

      [0]=> string(14) "/tmp/php1Nrgb4" 

      [1]=> string(14) "/tmp/phpnIJHZa" 

      [2]=> string(14) "/tmp/phpcAEf1c" 

      [3]=> string(14) "/tmp/phpbHgrVj" 

      [4]=> string(14) "/tmp/phpGu0FIp" 

    } 

    ["error"]=> array(5) { 

      [0]=> int(0) 

      [1]=> int(0) 

      [2]=> int(0) 

      [3]=> int(0) 

      [4]=> int(0) 

    } 

    ["size"]=> array(5) { 

      [0]=> int(262684) 

      [1]=> int(15644) 

      [2]=> int(32638) 

      [3]=> int(11897) 

      [4]=> int(103303) 

    }

  }

}

I'd also need ['type'] to test the files but same thing : I Can't get to return the array's content.

Do you see something wrong in this script ?

$_FILES['images']['tmp_name'] does not contain an extension, that is the temp file PHP made of the uploaded file.

If you want the filename with extension of the file that was uploaded from the users PC, you need to look in $_FILES['images']['name']

So

foreach($_FILES['images']['tmp_name'] as $index => $tmpName) {

    if(!empty($tmpName) && is_uploaded_file($tmpName)) {

        $img_url = url_rewrite($intitule)

                    .'-' 

                    . time()

                    . $i 

                    . '.'

                    . strtolower(substr(strrchr($_FILES['images']['name'][$index], '.'),1));

                    // changed here -----------------------------^^^^^^^^^^^^^^^^

        $gallery = $gallery . '|' . $img_url;

        move_uploaded_file( $tmpName, $dir_upload . '/' . $img_url);

    }

    $i++;

}

Also you can simplify that bunch of functions that get the extension to

        $img_url = url_rewrite($intitule)

                    .'-' 

                    . time()

                    . $i 

                    . '.'

                    . pathinfo($_FILES['images']['name'][$index], PATHINFO_EXTENSION);



        $gallery = $gallery . '|' . $img_url;
