Regarding the warning, the code in question is:
function loadConfigDefaults()
    $ret = loadConfigCache();
    if (!count ($ret))
        throw new RackTablesError ('Failed to load configuration from the database.', RackTablesError::INTERNAL);
    foreach ($ret as $varname => &$row)
        $row['is_altered'] = 'no';
        if ($row['vartype'] == 'uint')
            $row['varvalue'] = 0 + $row['varvalue'];

This used to cast the value to an integer.

Regarding PHP 7.1, on Ubuntu 17.04 it is available as an option (7.0 is the default).

I have tried Ubuntu 17.04 in a virtual machine and it does not have a PHP 7.1 option despite what Ubuntu web-site implies. To fix this bug there should be a way to reproduce it first.

sudo add-apt-repository -y ppa:ondrej/php

Thank you, let me try once again later.

I could reproduce this issue using Fedora 26, which comes with PHP 7.1 by default. There is no quick and simple solution to this particular problem, it requires some careful re-engineering.

From now on this issue is also visible in the Travis CI build of RackTables, which now includes a job with PHP 7.1 (which currently fails).

The master branch now has the PHP warning in that particular function resolved and Travis CI job for PHP 7.1 currently passes. But I have found that it is not a complete solution to the problem, there is at least one more place in the code that requires a fix so this bug remains open.

After some testing I had found that the remaining test failures on Fedora 26 were due to MariaDB, not PHP 7.1 (those are now fixed as well). Hence I consider this bug resolved, RackTables 0.21.0 will support PHP 7.1. Thank you for the report and feedback!
