I don't know why my script works when I declare arrays in my script, but doesn't work when I try to get array data from a database.

Perl

use Template;

my $template = Template->new;

if ( $info ) {

    my $select = $DBH->prepare("SELECT FOO, BAR, MOO FROM tble WHERE CONCAT(FOO, ', ', BAR, ', ', MOO) LIKE ?");
    $select->execute('%' . $info . '%');
    $names = $select->fetchall_arrayref();
    foreach $names ( @$names ) {
        ( $variable1, $variable2, $variable3 ) = @$names;
    }
}

my $templ = <<START_HTML;
<!DOCTYPE html">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1
+" />
<title>Untitled Document</title>
</head>

<body>

[% FOREACH name IN list %]
    <li>
      <div class='inforno'>
        <img src='inforno'>
      </div>
      <div class='inforno'>
        <a href='#' class='inforno'>[% name %]</a>
      </div>
      <span class='inforno'>
        <a href='#' class='inforno'>Edit user</a>
      </span>
    </li>
    [% END %]

</body>
    </html>
    START_HTML

$template->process($templ, { list => @$names })
        or die $template->error;

output

    ARRAY(0x2030674)
    ARRAY(0x2030634)
    ARRAY(0x2030618)

When I run I get that error. I want to get the array data from database.

fetchall_arrayref returns a reference to an array that has an element for each row returned by the query. Those elements are references to arrays with an element per column.

You are missing code to loop over the rows returned.
