I also suppose that PHP is a server scripting language and a significant tool for creating dynamic and interactive web pages. That's why we also suggest that you take the help of an expert at any time to solve your problem here: myhomeworkhelp.com/php-homework-answers/ ------------------------------------------------------------------------ [2022-09-06 14:06:49] peter dot maatman at rentman dot nl We are seeing this issue appear in production after we started migrating our production database servers from mysql 8.0.19 to 8.0.28. Our php version currently is 7.4.16 with pdo_mysql enabled, we run our php in a docker container based on the official php:7.4-fpm image. I can confirm that the test script reproduces the bug. ------------------------------------------------------------------------ [2022-03-07 16:20:31] maurice dot volaski at einsteinmed dot edu I am seeing this on my Mac with PHP 8.1.2 (Apache module) and MySQL 8.0.28 Homebrew. ------------------------------------------------------------------------ [2021-09-30 20:23:49] vovikems at gmail dot com Having same error using official docker images: php:8.0.9-cli and mysql:8.0.26. Typically this error seen on first DB query since long time (about 10h-15h) keeping DB connection without any query sent. Next query is always ok. FYI i'm using long-running php application (RoadRunner, Spiral Framework, CycleORM). ------------------------------------------------------------------------ [2021-09-14 12:27:24] cmb@php.net Oops, forgot about this. Anyway, result with git-master and MySQL 8.0.26: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away Is this Linux specific? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
