PHP - Classes and Objects

What will be the output of this PHP code?

class Sample {
  function __destruct() {
    echo "Goodbye!";
  }
}
$obj = new Sample();
echo "Hello!";
unset($obj);

AGoodbye!Hello!

BHello!Goodbye!

CHello!

DGoodbye!

Step-by-Step Solution

Solution:

Step 1: Analyze code execution order
First, the object is created but constructor is not defined, so no output. Then "Hello!" is printed.
Step 2: Understand unset effect
Calling unset($obj) destroys the object, triggering the destructor which prints "Goodbye!" immediately after "Hello!".
Final Answer:
Hello!Goodbye! -> Option B
Quick Check:
Destructor runs on unset = B [OK]

Quick Trick: Destructor runs when object is unset or script ends [OK]
