Adding PHP Validation to existing projects

So you have some PHP in a project and it is coded wrong!
What happens???
Well I will tell you it just crashes and ruins your day and you spend an hour looking for the problem, that is what.
Well you need to add the PDT nature to the project but how??
Well there is the hard way as seen here https://www.globalways.net/blog/archives/18-Converting-existing-eclipse-projects-into-PDT-projects.html ... which does work BTW!
Or the easy way....

1. In Eclipse select the project;
2. Right mouse click -->Configure-->Add PHP Support...

And that is it all PHPs are now validated ... happy days!
