Legend

Missed: lines code that were not excersized during program execution.
Covered: lines code were excersized during program execution.
Comment/non executable: Comment or non-executable line of code.
Dead: lines of code that according to xdebug could not be executed. This is counted as coverage code because in almost all cases it is code that runnable.
