how to add half star rating in php(calculation for $rating)

Question

How can I add half star and what will be the calculation for the rating system in php?

Check the following code and modify.

$rating = total rating from server.

I want calculation for $rating value if it is 1.3 - 1.7 it will add half star with color:orange else if 1 or 1.0 - 1.2 and 1.8 - 2.0 then it will add a fa-star with color:orange otherwise it will add a fa-star with color:#ccc.

Thanks for reading this question and for your help.

<?php
    $i;
    $color;

    for($i = 1; $i <= 5; $i++)
    {
        if($i <= $rating){ //$rating = total rating from server
            $color = "color:orange";
            echo "<i class='fa fa-star' style='$color;'></i>";
        } else {        
            $color = "color:#ccc";                 
            echo "<i class='fa fa-star' style='$color;'></i>";
        }
    }
?>

You should use client side rating library to use this functionality. In your scenario, PHP will only handle insert/update votes(ratings) in the database.

You can checkout javascript rating libraries here: https://www.jqueryscript.net/tags.php?/Rating/
