How to add php code to 'echo'?

Question

PHP

The form is rendered via 'echo' for each item. There is also a field for rating. Here's the suggested code, but how would you add it to 'echo' ? There may be other options for 'checked' radio depending on which rating is from 1 to 5 .

<?php $checked = 5;
           $count = 5;
?>
<?php for($i = 1; $i <= $count; $i++): ?>
    <?php if($i == $checked):?>
    <input class="rating-input" id="mod<?=$i?>'" name="radio-rating" type="radio" value="<?=$i?>" checked>
    <label class="rating-star" for="mod<?=$i?>" ></label>
    <?php else:?>
    <input class="rating-input" id="mod<?=$i?>'" name="radio-rating" type="radio" value="<?=$i?>">
    <label class="rating-star" for="mod<?=$i?>" ></label>
    <?php endif;?>
<?php endfor;?>

What is the problem? In laziness?

the code

<?php
$checked = 5;
$count = 5;
for($i = 1; $i <= $count; $i++) {
    $isChecked = $i == $checked ? 'checked' : '';
    echo "
    <input class='rating-input' id='mod{$i}' name='radio-rating' type='radio' value='{$i}' {$isChecked}>
    <label class='rating-star' for='mod{$i}' ></label>
    ";
}
