Comment by Sebastian Żmijewski [ 2017 Jan 17 ]

File include/func.inc.php

    function str2mem($val) {
        $val = trim($val);
        $last = strtolower(substr($val, -1));

        switch ($last) {
                case 'g':
                        $val = (int) $val * 1024;
                        /* falls through */
                case 'm':
                        $val = (int) $val * 1024;
                        /* falls through */
                case 'k':
                        $val = (int) $val * 1024;

        }

        return $val;

trying Sebastian Żmijewski changes with php 7.1.1 I still got the warning.
so i stripped the last char

function str2mem($val) {
        $val = trim($val);
        $last = strtolower(substr($val, -1));

        $val = substr_replace($val, "", -1);

        switch ($last) {
                case 'g':
                        $val *= $val * 1024;
                        /* falls through */
                case 'm':
                        $val *= $val * 1024;
                        /* falls through */
                case 'k':
                        $val *= $val * 1024;
        }

        return $val;
}

Still on 3.2.4. Fixed by adding "$val = (int)$val;" before switch statement.

Comment by Gregory Chalenko [ 2017 Mar 20 ]

In PHP7 strings containing hexadecimal numbers are no longer considered to be numeric.

Can anyone please explain how to apply this fix provided by Gregory Chalenko ?
I have zabbix 3.2 installed in ubuntu 16.04 machine.

Comment by Oleksandr Natalenko [ 2017 May 07 ]

tarmo, it's the same fix I've suggested previously

Wait for new package or go and edit relevant file directly.
