Coding Style Compatibility introduced by
PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

You can fix this by adding a namespace to your class:

namespace YourVendor;

class YourClass { }

When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.

This check looks for the bodies of if statements that have no statements or where all statements have been commented out. This may be the result of changes for debugging or the code may simply be obsolete.

These if bodies can be removed. If you have an empty if but statements in the else branch, consider inverting the condition.

Unused Code Comprehensibility introduced by
50% of this comment could be valid code. Did you maybe forget this after debugging?

Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it.

The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production.

This check looks for comments that seem to be mostly valid code and reports them.
