Increment number in php every time data is received from sql - php

Question

I am trying to make a program that can get data from Sql using php. the received data is a number from 1 to 5 and each number presents a color. every time a number is received a counter adds 1 for that color in html. I have been able to code this but if the page is refreshed the counted value becomes 0.
<?php
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC)) {
echo $row['name'].", ".$row['color']";
$red = "5";
$pink = "4";
$yellow = "3";
$black = "2";
$white = "1";
$colorid = $row['color'];
if ($colorid == $red){
echo "Red";
$re = 1;
$re = ++;
} elseif ($colorid == $pink){
echo "Pink";
$pi = 1;
$pi = ++;
} elseif ($colorid == $yellow){
echo "Yellow";
$ye = 1;
$ye = ++$;
} elseif ($colorid == $black){
echo "Black";
$blk = 1;
$blk = ++;
} elseif ($colorid == $white){
echo "White";
$wh = 1;
$wh = ++;
} else {
echo "Cannot verify the color code";
}
}
?>
<div>
<span>White: </span><input name="white" value="<?php echo (isset($wh))?$wh:'';?>">
<span>Black: </span><input name="black" value="<?php echo (isset($blk))?$blk:'';?>">
<span>Yellow: </span><input name="yellow" value="<?php echo (isset($ye))?$ye:'';?>">
<span>Pink: </span><input name="pink" value="<?php echo (isset($pi))?$pi:'';?>">
<span>Red : </span><input name="red" value="<?php echo (isset($re))?$re:'';?>">
</div>
