array

Question

how I can get an array and filter out entries with odd index number

Answer 1

@Andika had given you a sample, the only thing you need to do if you want the even elements would be this line:

if($i%2==1){

Into this..

if($i%2==0){

That's it :)

P.S. The % between $i and 2 is called modulo operator, it returns a remainder of $i divided by 2, so, even numbers are fully divisible by two, while odd numbers are not, there's a remainder left from the division. Hope it can shed a light a little.
