![]() ![]() There is a possibility that delta can be counted differently, but I suppose removing the continue will not affect the delta. Watchdog('feeds', check_plain($e->getMessage())) Īfter the switch code. ![]() Figure out how to properly populate this field. $field += (array) $v->getFile($destination, $mapping) If we have a switch inside a loop and wish to continue to the next iteration of the outer loop, use continue. So I just removed the continue statement because according to the experiments with try/catch block in the loop provided here:Ĭatch block suppresses the interruption thrown by an exception and the codeĬontinues to execute and gets to the last break statement. Continue statement can be used within switch,it acts similar to break. It means it behaves as a break statement.īut it also means we have two break statements in one case block. In our case the continue statement has no parameters set. If a switch is inside a loop, continue 2 will continue with the next iteration of the outer loop. continue behaves like break (when no arguments are passed). Note: In PHP the switch statement is considered a looping structure for the purposes of continue. Switch() //second looping structure - the closest one In our case we have this structure: foreach() //first looping structure The same result could have been achieved withīut if "case 2" represented a fairly common case (other than "everything else"), then it would be better to declare it explicitly, not only because it saves time by not having to test EVERY other case first (in the current example, PHP finds 'case 2' in the first switch in two tests, but in the second switch it has to make four tests before giving up and going with the default) but also because someone (perhaps yourself in a few months' time) will be reading the code and expecting to see it handled.As far as I understood from the example here:Ĭontinue 2 is targeting not the closest looping structure but the second closest. With case 2 and the default both producing the same result ("Thingy") strictly speaking, the case 2 clause is completely empty and control just falls straight through. Something not mentioned in the documentation itself, and only touched on momentarily in these notes, is that the default: case need not be the last clause in the switch. ![]() The answer to the eternal question " what is faster?": There's no need to preemptively save the result in a variable either. ![]() It instructs PHP to exit the switch statement and proceed to the next line of code after executing the. Without having to worry about the function being re-evaluated for every case. The break statement is used to end each case. I think this fact needs a little bit more attention, so here's an example: In this contrived example, I get out of the first case of the switch statement once a condition is met. The difference between a series of if statements and the switch statement is that the expression you're comparing with, is evaluated only once in a switch statement. You can use multiple break statements within a case. This is listed in the documentation above, but it's a bit tucked away between the paragraphs.
