计算for循环中的迭代次数

Question

Currently have this.

for ($i = 0; isset($house[$i]); $i++) {
     print $i++;
}

and it returns something like this. 0,1,2,3,4,5,6,7,8,9 I want it to return that same format, but replace the initial 0 with a 1 then count forward from there, how can I achieve this?

Answer 1

for ($i = 1; isset($house[$i-1]); $i++) {
   echo $i;
}

Like this?
