Continue statement with levels in PHP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the continue statement do in PHP loops?

The continue statement skips the rest of the current loop iteration and moves to the next iteration.

What is the purpose of using continue with a numeric argument (levels) in PHP?

Using continue with a number tells PHP to skip the rest of the current iteration of an outer loop that many levels up.

How does continue 2; behave inside nested loops?

continue 2; skips the rest of the current iteration of the inner loop and also skips the rest of the current iteration of the outer loop, moving to the next iteration of the outer loop.

beginner

Can continue be used outside of loops in PHP?

No, continue can only be used inside looping structures like for, foreach, while, and do-while loops.

advanced

What happens if you use continue with a level number greater than the number of nested loops?

PHP will generate a warning and treat it as a normal continue (level 1), skipping only the current loop iteration.

What does continue; do inside a loop?

A Exits the loop completely

B Restarts the entire program

C Skips the rest of the current iteration and moves to the next iteration

D Pauses the loop

continue; skips the rest of the current loop iteration and continues with the next iteration.

What does continue 2; do inside two nested loops?

A Exits both loops completely

B Skips the current iteration of the outer loop only

C Skips the current iteration of the inner loop only

D Skips the current iteration of both inner and outer loops

continue 2; skips the rest of the current iteration of the inner loop and also the outer loop, moving to the next iteration of the outer loop.

What happens if you use continue 3; inside two nested loops?

A PHP ignores the statement

B PHP treats it as <code>continue 1;</code> and skips only the inner loop iteration

C PHP throws a fatal error

D PHP skips three levels of loops

Using a level greater than the number of nested loops causes PHP to treat it as continue 1; and issue a warning.

Can continue be used inside a switch statement in PHP?

A No, <code>continue</code> is for loops only

B No, it causes a syntax error

C Yes, but only with levels

D Yes, it skips to the next case

continue is designed for loops, not switch statements.

Which of the following is a correct use of continue with levels?

A Inside nested loops to skip outer loop iterations

B To exit a function early

C To pause execution for a few seconds

D To restart the entire script

continue with levels is used inside nested loops to skip iterations of outer loops.

Explain how the continue statement with a numeric level works inside nested loops in PHP.

Think about how many loops you want to skip ahead in.

Describe what happens if you use a continue level number greater than the number of nested loops.

Consider PHP's behavior when the level is too high.
