Changes between Initial Version and Version 1 of Ticket #37738, comment 2

initial	v1
1	1	That ticket was really good to read. It helped me notice that the patch missed numeric strings such as '1' or '1.4'. In that ticket they used is_scalar but that returns true for 'apple' as well as '1'. I used is_numeric in this redone patch since it returns true for '1.36546' or '3' but not for '3rd' or 'apple'.

	4	Additionally negative integers don't seem to be a problem. They return false because the ID field in wp_posts is unsigned and as a result there are no posts with negative IDs. The code handles it the same as it would if there were no post with that number.
