Hi all, as it is now (for a long time), the PDO parser supports the proprietary backslash escapes for (double-)quotes in SQL string literals (the standard way to escape quootes in SQL strings is to double them). This causes string terminating quotes to be not recognized as such whenever they are immediately preceeded by a backslash. This has been reported as bug #79276[1], which shows a perfectly valid SQL query, which is not parsed correctly by the PDO parser. Another example which does currently not work as expected is part of the accompanying pull request[2].
Since I have not received much feedback on this so far, I'm bringing it up on the list: I think we should completely drop support for backslash escapes in the PDO parser as of PHP 8. If it was possible to support these without breaking other standard conforming SQL queries, it would be nice to keep it, but that doesn't seem to be possible. Thoughts?
