如何用php进行简单的星级评定？

Question

我想做一个星级展示。这是我的代码。

<?php $rate = 4; ?>

<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star_border</i>

我想这样做:例如，如果$rate =3显示3颗星，则显示2倍star_border。如果$rate =4显示4x星号，则1x star_border

下面是我写的太长的代码。我想要更短更实用的。

<?php $rate = 1;?>
<?php if ($rate == 1): ?>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star_border</i>
<i class="material-icons md-18">star_border</i>
<i class="material-icons md-18">star_border</i>
<i class="material-icons md-18">star_border</i>
<?php elseif ($rate == 2): ?>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star_border</i>
<i class="material-icons md-18">star_border</i>
<i class="material-icons md-18">star_border</i>
<?php elseif ($rate == 3): ?>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star_border</i>
<i class="material-icons md-18">star_border</i>
<?php elseif ($rate == 4): ?>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star_border</i>
<?php elseif ($rate == 5): ?>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<i class="material-icons md-18">star</i>
<?php endif;?>

Answer 1

这应该能很好地服务于你。

<?php
$rate = 3;
for ($x = 0; $x < $rate; $x++) {
    echo '<i class="material-icons md-18">star</i>';
}
for ($x = 0; $x < 5-$rate; $x++) {
    echo '<i class="material-icons md-18">star_border</i>';
}
?>

你回想起你的评级所说的那么多的首发。然后根据需要回显任意数量的星形边框。
