Thank you for your interest in PHP.
Thanks for the bug report. However, we need more information to be able to reproduce the issue.
Currently, we can't reproduce the issue. A lot of factors could cause this problem, and its
nature requires that we receive extremely thorough reproducible steps.
Please let us know:
- Platform (Windows/Linux/Mac)
- MySQL flavor and version e.g. MariaDB 10.4.1
- Whether mysqli was compiled against libmysqlclient or mysqlnd
- Which connection method was used (TCP/IP or socket or named pipe)
- Your table schema. (SHOW CREATE TABLE tbl_name) including charset used for connection and table
storage.
- The character encoding of your file. Are you using UTF-8?
- Are you using utf8mb4 charset? Did you set the charset via set_charset() method?
- HEX dump of the query string producing the error. (There could be a hidden character there)
- HEX dump of the sample data causing the error.
- Self contained reproducible example. http://sscce.org/ should help
you make such an example.
We would love to hear back from you and if possible fix the bug you have reported.

well - yes its reproducible
if I found some SQL which give this error - this error repeat each time this SQL is used
So i can reproduce it 1000 times if i want but I dont know how to find this SQL - I found one and i
know how to check it. But I dont have ideas why exact this SQL statement give me this error..

How reproducible is this issue? Is this something you see every time, or more something that happens
rarely and randomly?

Description:
------------
Hi
Im using php 7.4.10 and i cant simply upgrade it to 7.4.12 if im not sure it will resolve problem
because its production server and situation is unique and its difficult to find another such
situations. So for now while i found it im not changing nothing in server configuration till ill
find answer.
First of all - this bug happen in some random cases but when it happen in some my part of code - it
happen always.
Problem is in creating mysql requests using mysqli library. In some sql statements it creates
problems like "Packets out of order. Expected 1 received 0". I noticed that it doesnt
depend on mysql configuration because i have many same databases with same access and many same
tables with same structure and all is same and all works but some sql statements return this error
ALSO what is very strange - i change sql request with adding one space and it start working. It mean
that there is something basic wrong with networking in php
Test script:
---------------
//.... im connecting to db and so on and then
$la=$db->query('SELECT * FROM voipe_481.labels_auto');
//here i put additional space between FROM and database name - and it works OK
$la=$db->query('SELECT * FROM voipe_481.labels_auto');
// here it write Warning and disconnects from server
//PHP Warning: Packets out of order. Expected 1 received 0. Packet size=1
Expected result:
----------------
both sql requests must work fine
Actual result:
--------------
first sql request works fine, second crashes connection to database
Interesting is that im checking $db->ping before each request and it is ok but after second
request it is false
