PHP - Request Lifecycle

Consider this PHP code run twice in a row (two separate page loads):

<?php
$counter = 0;
$counter++;
echo $counter;
?>

What will be the output each time the script runs?

A1 then 1

B0 then 1

C1 then 2

D0 then 0

Step-by-Step Solution

Solution:

Step 1: Analyze variable initialization
Each time the script runs, $counter is set to 0 at the start.
Step 2: Increment and output
$counter++ increases $counter to 1, then echo prints 1 each time.
Final Answer:
1 then 1 -> Option A
Quick Check:
Variables reset each run, so output is 1 each time [OK]

Quick Trick: Variables reset each run, so counter restarts at 0 [OK]
