Reports the usages of the comparison operator (==) for comparing object variables.

Object variables are compared as follows:

• When using the comparison operator (==), two object instances are considered equal if they have the same attributes and values (values are compared with ==), and are instances of the same class.

• When using the identity operator (===), object variables are considered identical if and only if they refer to the same instance of the same class.

See Comparing Objects (php.net) for details.
