PHP - Loops

You want to print numbers from 10 down to 1 using a do-while loop in PHP. Which code snippet correctly achieves this?

A$num = 10; do { echo $num . ' '; $num++; } while ($num > 0);

B$num = 1; do { echo $num . ' '; $num++; } while ($num <= 10);

C$num = 10; do { echo $num . ' '; $num--; } while ($num >= 1);

D$num = 1; do { echo $num . ' '; $num--; } while ($num < 10);

Step-by-Step Solution

Solution:

Step 1: Understand the goal
We want to print from 10 down to 1, so start at 10 and decrement.
Step 2: Check each option
$num = 10; do { echo $num . ' '; $num--; } while ($num >= 1); starts at 10, decrements, and loops while >= 1, which matches the goal.
Final Answer:
$num = 10; do { echo $num . ' '; $num--; } while ($num >= 1); -> Option C
Quick Check:
Start high, decrement, loop while condition true [OK]

Quick Trick: Count down with decrement and condition >= 1 [OK]
