array math exponential

Hi I need to make an dynamic array like this:

I have a max number of 25000 and 62 as exponential(?) number.

Array
(
    [0] => 0  
    [1] => 3844     // 62 * 62
    [2] => 238328   // 62 * 62 * 62 <---
    [3] => 14776336 // 62 * 62 * 62 * 62
)

This is just an example of what I need: calculate the array values and find where fit the max number.

Any Ideas?

Solution 
  • $max =  floor(log(25000,62));
$array = array_map(function($value){return pow(62,$value);},range(0,$max);

    Or, in a total function:

    function getpowers($base, $maxvalue){
    $max = floor(log($maxvalue,$base));
    return array_map(function($value) use ( $base ) {return pow($base,$value);},range(0,$max));
}
var_dump(getpowers(62,25000));
