From: kelvin dot middleton at gmail dot com Operating system: Ubuntu 16.04 PHP version: 7.0.17 Package: MySQLi related Bug Type: Bug Bug description:mysqli_fetch_array(): Malformed server packet & Error while reading a row... Description: ------------ Initially found a problem with phpMyAdmin not returning slave information in a master/slave replication configuration. Issue raised their concluded the problem likely resided in PHP somewhere (https://github.com/phpmyadmin/phpmyadmin/issues/13117). Was using stock php package from ubuntu ppa (ver 7.0.15-0ubuntu0.16.04.4) so I raised a launchpad bug (https://bugs.launchpad.net/ubuntu/+source/php7.0/+bug/1675117) which progressed to providing me with a ppa to test php 7.0.17. Testing still has the same errors when using the test script. Test script: --------------- Script is included in my bug submission here https://bugs.launchpad.net/ubuntu/+source/php7.0/+bug/1675117 Actual result: -------------- Two errors return, excerpt below... kelvin@xxx-server:~$ php php_test.php PHP Warning: mysqli_fetch_array(): Malformed server packet.
