Bug introduced by
The variable $calleeSource does not exist. Did you mean $source?

This check looks for variables that are accessed but have not been defined. It raises an issue if it finds another variable that has a similar name.

The variable may have been renamed without also renaming all references.

Bug introduced by
The variable $methodName does not exist. Did you forget to declare it?

This check marks access to variables or properties that have not been declared yet. While PHP has no explicit notion of declaring a variable, accessing it before a value is assigned to it is most likely a bug.

Unused Code introduced by
$callee is not used, you could remove the assignment.

This check looks for variable assignements that are either overwritten by other assignments or where the variable is not used subsequently.

$myVar = 'Value';
$higher = false;

if (rand(1, 6) > 3) {
    $higher = true;
} else {
    $higher = false;
}

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.
