Fix warning PHP 7.3
#216

Hi, you seem to have replaced all continue statements even though only the ones in switch statements should be replaced. There are quite some continue statements in foreach loops which should probably stay, no?

[jonthekiller]

You are right, I have rollback this part.

maybe the if(!...) should be reversed that the code below gets carried out within the IF so the break is not needed anymore.

[kremsy]

seems like a solution, but bette rwould be to change the

if(!a || !b) {
break;
}
somecode
break;

to

if(a && b) {
somecode
}

break;

to avoid multiple breaks
