Step-by-Step Solution
Solution:
Step 1: Outer loop for rows
The outer loop runs 3 times, each representing a row.Step 2: Inner loop for columns
The inner loop runs 3 times per row, printing '*' without newline.Step 3: Print newline after each row
After inner loop finishes,echo "\n";moves to the next line.Final Answer:
for ($i = 1; $i <= 3; $i++) { for ($j = 1; $j <= 3; $j++) { echo '*'; } echo "\n"; } correctly prints a 3x3 grid with rows on new lines.Quick Check:
Newline after inner loop completes each row [OK]
Quick Trick: Print newline after inner loop to separate rows [OK]
Common Mistakes:
- Printing newline inside inner loop
- Not printing newline at all
- Incorrect loop boundaries
