Continue statement with levels in PHP - Mini Project: Build & Apply

Continue Statement with Levels in PHP

📖 Scenario: Imagine you are organizing a small event with multiple sessions. You want to skip certain sessions or parts of sessions based on specific conditions.

🎯 Goal: You will write a PHP script that uses nested loops to represent sessions and their parts. You will use the continue statement with levels to skip parts or entire sessions.

📋 What You'll Learn

Create a nested loop structure with two levels: sessions and parts

Use a continue statement with a level to skip a part inside a session

Use a continue statement with a level to skip an entire session

Print the parts that are not skipped

💡 Why This Matters

🌍 Real World

Skipping parts of nested loops is useful when processing multi-level data, like events with sessions and parts, or files with folders and subfolders.

💼 Career

Understanding loop control with levels helps in writing efficient PHP scripts for web applications, data processing, and automation tasks.

1

Create nested loops for sessions and parts

Create a for loop with variable $session from 1 to 3 and inside it create another for loop with variable $part from 1 to 4.

PHP

Need a hint?

Use two for loops, one inside the other, with the exact variable names $session and $part.

2

Add a condition to skip part 3 in session 2

Add an if statement inside the inner loop to check if $session is 2 and $part is 3. Use continue 1; to skip only this part.

PHP

Need a hint?

Use continue 1; to skip only the current iteration of the inner loop.

3

Add a condition to skip entire session 3

Add an if statement inside the inner loop to check if $session is 3. Use continue 2; to skip the entire session including all its parts.

PHP

Need a hint?

Use continue 2; to skip the current iteration of the outer loop from inside the inner loop.

4

Print the session and part numbers that are not skipped

Inside the inner loop, after the continue statements, add a print statement to display "Session $session - Part $part\n".

PHP

Need a hint?

Use print("Session $session - Part $part\n"); to show the current session and part.
