Responsive layouts are very difficult to test. It is more tedious to design and test all of a project’s screen elements at every breakpoint than it is to code them in the first place. Visual regression allows you to make visual comparisons between the baseline versions of the site and the version in development. The complete process is nothing but taking the screenshot of the original design and comparing it with the new, looking for pixel differences. Visual regression comes in various flavors, using a variety of technologies and workflows as mentioned below. Pick any one to suit your purpose.

Automatically create PHP classes from MySQL
Creating a database driven web application involves commonly used paradigms for data modification, which we commonly refer to as CRUD. Frameworks provides nice ORM wrappers to help the programmer. But for small projects frameworks can be an overkill. Still the programmer needs to design the basic database CRUD functionality, which can be quite tedious and repetitive. This is where auto database class generators can be helpful. If you have your database schema ready, you can automatically create the respective class wrappers for the tables.

Detecting duplicate code in PHP files
Duplicated code in projects is a frequent thing and also the one ripe for factoring out in a new class or function. Cut/Paste coding is a common development practice among programmers, a lot of which can lead to code size increase and maintenance nightmares. PHPCPD (php copy paste detector) is a PEAR tool that makes it easier to detect duplicate code in php projects. Below is a short tutorial on the PHPCPD package.

Checking coding standards with PHP_Codesniffer
One of the important factors in developing a successful software product is the application of coding standards. And by successful I mean a product that is easy to develop, modify and maintain. Every developer likes to code in a particular style: in the way he declares variables or function blocks, the number of indentation spaces, commenting style etc. Giving every developer in a team complete freedom to use whatever style he likes will very likely result in a code that is hard to understand, modify and maintain. Even though every coding standard has its good points and bad; the important thing is to try to adhere to a particular one.
