Both the $myVar assignment in line 1 and the $higher assignment in line 2
are dead. The first because $myVar is never used and the second because
$higher is always overwritten for every possible time line.
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.
This check looks for variable assignements that are either overwritten by other assignments or where the variable is not used subsequently.
