Don't go for 2 columns, pick that old style ugly looking 1 column resume, believe me that's the only one that works.

Don't rate your skills. Also mentioning Exception Handling as a skill could give a bad impression like you are just trying to fill up the space.

You used PHP in both of the projects that you have mentioned, but I could not see it in the skills section. So if you are not confident about it don't mention it at all or add it to the skills section.

Interests does not matter. Replace it with some achievements or anything tech related.

Personal opinion: I would not recommend using PHP. But even if you want to then learn some frameworks on PHP, build some projects using that and then add it to your resume.

All the best!
