[RFC] Escape PDO "?" parameter placeholder

Hi everyone, following some recent unrest in the comments of the related PR, I've decided to invest a bit of time on it and finally move it to draft status: https://wiki.php.net/rfc/pdo_escape_placeholders The PR is currently closed, but I will soon rebase and update it. Any feedback kindly accepted! Cheers -- Matteo Beccati Development & Consulting - http://www.beccati.com/
