「實際幸得@馬克·貝克」

但在這裏，我只是把它在一個良好的狀態，在這裏正是你如何能做到這一點：

<?php 
$grid = range(6, -15, 0.25); 
echo "<pre>"; 
print_r($grid); 
echo "</pre>"; 
?> 

這裏是代碼的輸出：

Array 
(
    [0] => 6 
    [1] => 5.75 
    [2] => 5.5 
    [3] => 5.25 
    [4] => 5 
    [5] => 4.75 
    [6] => 4.5 
    [7] => 4.25 
    [8] => 4 
    [9] => 3.75
