You could try setting the Input Record Separator to '@user_info_end': 


...

# set the Input Record Separator
$/ = '@user_info_end';

while ( my $file_content = <FILE> ) {
    # remove the Input Record Separator
    chomp $file_content;
    if ( $file_content =~ /\@user_info_start.*\n)(?s:(.*))/i ) {
        $user_info = $2;
        }
    ...
    }
