在循环中划分PHP [关闭]

So this code will make a while loop that will subtract 1 from the score at each loop until it reaches 6500 in score.

<?php
$i = $rows[score];
while ($i != 6500) {
    echo $i--; 
}

?>

But this is not what I want. What I want is to divide the score with 2 at each loop, until it reaches 6500.

Edited the code

<?php
$i = $rows[score];
$j = $i;
while ($i <= 6500) {
echo $j; 
$j = $j/2;
$i--;
}

?>

Best to use <= comparision as the division is unlikely to hit 6500.

$i = $rows[score];
while ($i <= 6500) {
    echo $i = $i /2; 
}

$i = $rows[score];
while ($i <= 6500) {
    $i /= 2;
    echo $i; 
}

Something like this, maybe?

while( $i > 6500 ){
    $i /= 2;
}
echo $i;
