php numeric value to html array

Question

I have a numeric value from an array

<p><b>Rating</b>: <?= $arr->rating; ?></p>

which outputs in browser source code

<p><b>Rating</b>: 5.100000</p>

(This is a rating of 5.100000 out of 10.)

How would I go about displaying the rating numeric value as an array of five stars?

For example, the 5.100000 values would be displayed as two and 1/2 stars out of five like this.

<li>
    <i class="glyphicon glyphicon-star"></i>
    <i class="glyphicon glyphicon-star"></i>
    <i class="glyphicon glyphicon-star half"></i>
    <i class="glyphicon glyphicon-star empty"></i>
    <i class="glyphicon glyphicon-star empty"></i>
</li>

html... array...? That's not a thing. Your question is very hard to understand. — GrumpyCrouton

can you give us an example of what you need as final result? — Jonathan

I think what you're trying to say is that you want to automatically generate the required number of stars (and half stars) based on a number. — Difster

"how can 5.1 result in 2.5 stars" 5.1 out of 10 rounds to 5. the conversion is 1/2-5 stars out of a 1-10 rating. — jasenmichael

Use a for loop and compare the current loop iteration to $arr->rating to determine whether the star should be full, half, or empty.

// first convert the rating from score out of ten to score out of five
$rating = $arr->rating / 2;  

for ($i=0; $i < 5; $i++) {
    $current = $rating - $i;
    if ($current >= 1) {
        $class = '';
    } elseif ($current > 0) {
        $class = 'half';
    } else {
        $class = 'empty';
    }
    echo "<i class=\"glyphicon glyphicon-star $class\"></i>";
} ?>

I think $current = $arr->rating - $i; should be $current = $rating - $i;
