This is not a support forum.  Please ask support questions on the appropriate mailing list.

But your logic boils down to:

if(true) echo "here1"; else <empty expression>;
if(true) echo "here2";

if(true) echo "here3";
else if(true) echo "here4";

In the first part you don't have anything in your else clause as you never started a block using {...} so the expression ends with the end of the PHP block.

In the second part the else expression only gets evaluated if the if condition was false.  It doesn't matter that the condition after the else happens to be true, it won't be evaluated.
