PHP: Change color of text based on $value

Question

What's the easiest way to change a text's color based on a variable?

For example: If $var is between 1-5, green. Between 6-10, Orange. Greater than 11, Red.

Answer 1

function getProperColor($number)
{
    if ($var > 0 && $var <= 5)
        return '#00FF00';
    else if ($var >= 6 && $var <= 10)
        return = '#FF8000';
    else if ($var >= 11)
        return = '#FF0000';
}

And use it like this

<div style="background-color: <?=getProperColor($result['number'])?>;"><?=$result["title"]?></div>

Answer 2

$color = "#000000";

if (($v >= 1) && ($v <= 5))
   $color = "#00FF00";
else if (($v >= 6) && ($v <= 10))
   $color = "#FF9900";
else if ($v >= 11)
   $color = "#FF0000";

echo "<span style=\"color: $color\">Text</span>";

Answer 3

Are color values indexed by constants? I would prepare hash map

$colorMap[0] = '#00FF00'; //green
$colorMap[1] = '#0000FF'; //blue
$colorMap[2] = '#FF0000'; //red
$colorMap[3] = '#330000'; //dark red

and so on. Then use CSS

<span style="color: <?php echo $colorMap[$var]; ?>;">desired color</span>
