Here is some aditions that are allowed, but not enforced by PSR-12:

2.3 Lines

• PSR-12 says:
  • Blank lines MAY be added to improve readability and to indicate related blocks of code except where explicitly forbidden.
• I add:
  • There MUST NOT be more then one consecutive blank line.

3. Declare Statements, Namespace, and Import Statements

• PSR-12 says:
  • Compound namespaces with a depth of more than two MUST NOT be used.
• I add:
  • Compound namespaces MUST NOT be used.

5.1 if, elseif, else

• PSR-12 says:
  • Boolean operators between conditions MUST always be at the beginning or at the end of the line, not a mix of both.
• I add:
  • Boolean operators between conditions MUST always be at the end of the line.

6.1. Unary operators

• PSR-12 says:
  • nothing about the ! operator
• I add:
  • The ! Operator MUST NOT have any space between the operator and operand.
