Tried with below code but it does not work

     <?php
      $start = 1;
      $end = 3;
      $place = 0.5;

      $step = 0.05 / pow(10, $place);

      for($i = $start; $i <= $end; $i = round($i + $step, $place))
      {
          echo $i . "
";
      }

      ?>

You can build a range of the values needed.
Here I create from 0 -> 5 with 0.05 increment.

$range = range(0, 5, 0.05);

foreach($range as $val){
    echo number_format($val, 2) . "
";
}

If the decimals are not important a simpler way to output would be with implode.

echo implode("
", $range);
