Not a recomended way of doing things but:

$arr = array();
for($i=0;$i<5;$i++) {
    $varName = 'number_'.$i;
    $arr[] = $$varName;
}

I was about to ask a similar question, can you explain why it's not recommended, The only variance in my question is that I might add new Variables and I don't want to change numbers every time I would like PHP to detect the number of variables.
variable variable names are not a good practice, generally there is always a better way of doing something than with variable-variables, but very very rarely there isn't..

for ($i = 1; $i <= 6; $i++)
    $ar[] = $i;
