[SOLVED] Accumulative repetition

[448191]

I suck at math.

 

What I want is an array who's values are accumulatively repeated by some factor.

 

I don't have a clue how to accomplish this.

for ($i=0;$i<$max;$i++) {
   $arr[$i] = some_function(of $i, some factor, maybe $arr[$i-1], etc ???);
}

 

Seems too trivial to be the answer.  Clue me in on 'accumulatively repeated'.

As soon as you posted that, I realized I what I meant to say is I need exponential growth of repetition, not accumulative. So thanks for being confused 

 

<?php
$array = array();
$base = 2;
$fill = array('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h');
for($i = 1; $i < count($fill); ++$i){
$array = array_merge($array, array_fill(0, pow($base, $i), current($fill)));
next($fill);
}
var_dump($array);
?>

 

I feel a bit stupid for not thinking of this right away. Anyway. Thanks for reading
