Sending attachment using email as file name with Phpmailer

Question

I am using Phpmailer to send a form and I would like the attached files when they arrived in the email destination, had the file name the email of the person from whom I send, and not the file name, I did several tests here but could not.

<input type="file" name="arquivo[]" multiple>

$email = strip_tags(trim($_POST['email']));
$arquivo = $_FILES['arquivo'];

if ($arquivo['size'][0] != 0) {
    for ($i = 0; $i < count($arquivo ['tmp_name']); $i++) {
        $mail->AddAttachment($arquivo ['tmp_name'][$i], $arquivo['name'][$i]);
    }
}

Answer 1

The code $email[$i] will only take the first character of the string. In the case of for, when the variable $i is equal to 0, will take the first character (the 0 represents the index of the first character of a string). Example:

$str = "Olá";
$str[0] -> O
$str[1] -> l
$str[2] -> á

Put only the variable $email concatenating with the variable $i, since the $email is not part of the array, it is a fixed value variable:

$mail->AddAttachment($arquivo ['tmp_name'][$i], $email.$i);
