PHP - Functions

$x = 5;
function test() {
    $x = 10;
    echo $x;
}
test();
echo $x;

A10 5

B5 10

C10 10

D5 5

Step-by-Step Solution

Solution:

Step 1: Analyze variable scope inside the function
Inside test(), $x is assigned 10 locally, so echo $x; prints 10.
Step 2: Analyze variable outside the function
Outside the function, $x remains 5 because the local $x inside the function does not affect the global $x.
Final Answer:
10 5 -> Option A
Quick Check:
Local $x = 10, global $x = 5 [OK]

Quick Trick: Local variables inside functions do not change globals [OK]
