PHP 7.3 causes fatal error

  • When I try to enable PHP 7.3 for my site, there is a fatal error:

    [23-Sep-2019 18:41:54 UTC] PHP Fatal error: Uncaught Error: Undefined class constant ‘MYSQL_ATTR_INIT_COMMAND’ in /home/myusername/public_html/wp-content/plugins/mailpoet/lib/Doctrine/ConnectionFactory.php:68

    #5 / in /home/myusername/public_html/wp-content/plugins/mailpoet/lib/Doctrine/ConnectionFactory.php on line 68

    Is MailPoet compatible with PHP 7.3? If so, any ideas what is happening?

  • Hi Scott!

    We use PHP 7.3 ourselves and haven’t run into this, though a few other users have reported the same.

    Does it still happen with the latest release?

    Can you let us know which MySQL or MariaDB version you’re using, please?

    Thanks!

    Same problem with me. Follows the database version;
    Server version: 5.6.35-log MySQL Community Server (GPL)

    Yes, problem still exists in 3.37.1. For db server, it is 10.1.41-MariaDB. I have created a phpinfo for you, and printed to a PDF file, and shared via Google Drive:

    https://drive.google.com/file/d/1xqJ5ZQafTpVJnVkuQCa-56YlCLDFEEKi/view?usp=sharing

    FYI, I am the root server owner, so if there is any other info I can help with, let me know.

    I had this same error message, and in my case it turned out to be related to not having the pdo extension installed.

    This is my complete dockerfile now. Without installing pdo pdo_mysql as per the dockerfile below, it would throw this exact error. This works nicely both with php 5.6.20 and php 7.3.

    If you don’t use docker, you may still want to check you have the pdo and pdo_mysql extensions enabled.

    
FROM php:7.3-apache

RUN apt-get update

RUN apt-get install -y libzip-dev zlib1g-dev

RUN docker-php-ext-install zip mysqli pdo pdo_mysql

RUN a2enmod rewrite

    I can confirm that I can fix the issue by enabling the pdo_mysql extension.
