200-710 Exam - Question 18

Question

What is the output of the following code?

Examice · Accepted Answer

The code demonstrates object-oriented programming in PHP. The 'Test' class defines a public variable 'var' initialized to 1. An instance of the Test class is then created and passed to the 'addMe' function. Inside the 'addMe' function, the 'var' property of the passed object is incremented by 1. As a result, after calling 'addMe', the 'var' property of the 'Test' instance 't' becomes 2. Hence, when 'echo $t->var;' is executed, it outputs 2.
