It seems like you call parent on a different method (valid() instead of lazyAppend()). Are you sure this is correct? If so, you might want to change this to $this->valid().
This check looks for a call to a parent method whose name is different than
the method from which it is called.
Using logical operators such as and instead of && is generally not recommended.
PHP has two types of connecting operators (logical operators, and boolean operators):
Logical Operators
Boolean Operator
AND - meaning
and
&&
OR - meaning
or
||
The difference between these is the order in which they are executed. In most cases,
you would want to use a boolean operator like &&, or ||.
Let’s take a look at a few examples:
// Logical operators have lower precedence:$f=falseortrue;// is executed like this:($f=false)ortrue;// Boolean operators have higher precedence:$f=false||true;// is executed like this:$f=(false||true);
Logical Operators are used for Control-Flow
One case where you explicitly want to use logical operators is for control-flow
such as this:
$x===5ordie('$x must be 5.');// Instead ofif($x!==5){die('$x must be 5.');}
Since die introduces problems of its own, f.e. it makes our code hardly
testable, and prevents any kind of more sophisticated error handling; you probably
do not want to use this in real-world code. Unfortunately, logical operators
cannot be combined with throw at this point:
// The following is currently a parse error.$x===5orthrownewRuntimeException('$x must be 5.');
These limitations lead to logical operators rarely being of use in current
PHP code.

This check looks for a call to a parent method whose name is different than the method from which it is called.
Consider the following code:
The
getFirstName()method in theSoncalls the wrong method in the parent class.
