I had read that WordPress 6.4 was to have beta core support for PHP 8.3, and as always, I was excited to update PHP when it became available.
Recently, I noticed that PHP 8.3 was available within Ubuntu, so I bit the bullet and upgraded. I am not planning on rolling this out to customer sites just yet since one of them, if not more than one, will have some issues with the newest update due in some part to an obscure plugin or theme.
So far, though, I have not noticed any issues popping up, and the error logs are not filling up with anything out of the ordinary, so I chalk this up to a win… for now.
