Warning: A non-numeric value encountered

Question

Recently updated to PHP 7.1 and start getting following error

Warning: A non-numeric value encountered in on line 29

Here is wha

Answer 1

This was happening to me specifically on PHPMyAdmin. So to more specifically answer this, I did the following:

In File:

C:\ampps\phpMyAdmin\libraries\DisplayResults.class.php

I changed this:

// Move to the next page or to the last one
$endpos = $_SESSION['tmpval']['pos']
    + $_SESSION['tmpval']['max_rows'];

To this:

$endpos = 0;
if (!empty($_SESSION['tmpval']['pos']) && is_numeric($_SESSION['tmpval']['pos'])) {
    $endpos += $_SESSION['tmpval']['pos'];
}
if (!empty($_SESSION['tmpval']['max_rows']) && is_numeric($_SESSION['tmpval']['max_rows'])) {
    $endpos += $_SESSION['tmpval']['max_rows'];
}

Hope that save's someone some trouble...
