Udemy PHP Security

Link to the course

It was a short simple course taught by Edwin Diaz for twelve dollars. I took the course just as a refresher since security is always changing. Overall it had limited helpfulness since I already knew most of the course work. The course topics follow this flow: build a vulnerable webpage, break the page, secure the page. It is a nice format since students can 'see' the problem however the course doesn't go deeper than that.
