Fix PHP 8.5+ deprecation for PDO::MYSQL_ATTR_SSL_CA

[whygareth]

Summary

This PR addresses the deprecation warning for PDO::MYSQL_ATTR_SSL_CA introduced in PHP 8.4 (and present in PHP 8.5 builds).

The Issue

In newer PHP versions, the PDO::MYSQL_ATTR_SSL_CA constant is deprecated in favor of the namespaced Pdo\Mysql::ATTR_SSL_CA. Using the old constant results in a deprecation notice.

The Solution

I have updated config/database.php to use a conditional check. The configuration now uses the new Pdo\Mysql::ATTR_SSL_CA constant if it is defined, while falling back to the legacy PDO::MYSQL_ATTR_SSL_CA constant for older PHP versions to ensure backward compatibility.

Affects

• MySQL connection
• MariaDB connection
• WordPress connection

Hey thanks for this! It looks like this was actually addressed in Laravel a few days ago. Would you want to copy over the exact fix they did in https://github.com/laravel/laravel/blob/12.x/config/database.php ? Namely checking the PHP version.

Good call! Thanks for the heads up.
I've updated the check to use PHP_VERSION_ID, but I stuck with 80400 (PHP 8.4) instead of 80500. Since the deprecation starts in 8.4, using 80500 would sadly leave those users with the warning still active.
