Code Inspection: Non-strict object equality
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.
