Description (last modified by SergeyBiryukov)

WP_Site_Health::prepare_sql_data() has this fragment, introduced in [44986] / #46573:

if ( $wpdb->use_mysqli ) {
	// phpcs:ignore WordPress.DB.RestrictedFunctions.mysql_mysqli_get_server_info
	$mysql_server_type = mysqli_get_server_info( $wpdb->dbh );
} else {
	// phpcs:ignore WordPress.DB.RestrictedFunctions.mysql_mysql_get_server_info,PHPCompatibility.Extensions.RemovedExtensions.mysql_DeprecatedRemoved
	$mysql_server_type = mysql_get_server_info( $wpdb->dbh );

This can be replaced with:

$mysql_server_type = $wpdb->db_server_info();

The db_server_info() method has the exact same code and is available as of [47451] / #40037.

Hi there!

Thanks for the patch! It looks good to me too.

I had a concern about whether this method would be available in custom database drop-ins (wp-content/db.php), but it looks like they are loaded after wpdb, and are supposed to extend the class, rather than completely replace it, though technically the latter is possible too.

@Clorith, do you think this change is safe as is, or should we check if the method exists, just in case, and fall back to the current code if it doesn't? Upon a quick check, popular drop-ins like HyperDB extend the wpdb class, so the patch seems good to go.

I agree that this seems good as is.

I also did some checking, and no plugins I could spot were doing it any other way than by extending, so don't think its a thing we need to be concerned with :)

In 54065:

Site Health: Use $wpdb->db_server_info() to retrieve database server type.

This updates an older fragment in WP_Site_Health::prepare_sql_data() to use a dedicated $wpdb method introduced later in WordPress 5.5 specifically for retrieving the database server information.

Follow-up to [44986], [47451].

Props hilayt24, mukesh27, Clorith, SergeyBiryukov.
Fixes #56484.
