PHP - Functions

Consider this PHP code:

$val = 1;
function test() {
  static $val = 0;
  $val++;
  echo $val . ' ';
}
test();
test();
echo $val;

What is the output?

A1 2 2

B1 1 1

C0 1 1

D1 2 1

Step-by-Step Solution

Solution:

Step 1: Analyze static variable behavior inside function
The static $val inside test() starts at 0 and increments each call, printing 1 then 2.
Step 2: Analyze global variable outside function
The global $val remains 1, printed after function calls.
Final Answer:
1 2 1 -> Option D
Quick Check:
Static inside function increments, global unchanged = 1 2 1 [OK]

Quick Trick: Static variables keep value inside function; globals stay separate [OK]
