Note Submitter: none at example dot com ---- A note on continue, continue 2, and break: $a = [1, 2, 3]; foreach($a as $b) { switch($b) { case 1: echo 'a'; continue; case 2: echo 'b'; continue; default: echo 'c'; continue; } echo '0'; } // outputs a0b0c0 (and warns twice about continue in a switch statement) foreach($a as $b) { switch($b) { case 1: echo 'a'; break; case 2: echo 'b'; break; default: echo 'c'; break; } echo '0'; } // outputs a0b0c0 foreach($a as $b) { switch($b) { case 1: echo 'a'; continue 2; case 2: echo 'b'; continue 2; default: echo 'c'; continue 2; } echo '0'; } //outputs abc0 In short, continue and break will more or less behave the same (albeit the former throws out warnings), but continue 2 will end the loop iteration, and move to the next iteration (even if there is a block in the iteration after the switch statement).
