    Because you're using literal quotes, so PHP is literally looking
for the POST reference 'referral_$i'.

    Instead of using the style of field names you're using, why not
use a virtually limitless array?

<?php

if (isset($_POST['referral']) && is_array($_POST['referral'])) {
    $refcnt = count($_POST['referral']);
    for ($i=0;$i<$refcnt;$i++) {
        echo 'Referral #'.$i.': '.$_POST['referral'][$i].'<br/>'.PHP_EOL;
    }
}
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <?php
    for ($i=1;$i<6;$i++) {
        echo ' &nbsp; &nbsp;<input type="text" name="referral[]"
id="referral_'.$i.'"/><br/>'.PHP_EOL;
    }
    ?>
    <input type="submit" id="submitButton" value="Send"/>
</form>
