conditional formatting comparing two fields values

I need to evaluate several fields values and place condition based on their value.
Like if [ Date fields] => Now then

.....
Else if

[Status field] =='comp'

.....
****

I am able to use custom settings to evaluate a single fields value and place some condition see the below.

Code

if ($value >= now()) {
$value = $value. ' <img src="./images/green.png" alt="" />';
$color="black";
} else {
$value ='<strong>'.$value. '</strong> <img src="./images/red.png" alt="" />';
$color="red";

}
$value="<span style='color: " . $color . ";'>".$value."</span>";

**End Code***
