problem with declaring variable in php?

Question

i have a variables like $srange0 , $srange1, $srange2 $srange3.

i am using to declare some value to each value using for loop.

for($i=0;$i<=3;$i++){
  $srange.$i = $i;
}

but its not working ?

is there any alternative solution for this

Answer 1

for($i=0;$i<=3;$i++){
  $var = 'srange'.$i;
  $$var = $i;
}

But, whenever I see variables like that, I'd use an array instead.
