如何从生成的数字列表中删除最后一个竖线？
$days = new DatePeriod(new DateTime, new DateInterval('P1D'), 6);
foreach ($days as $day) {
echo strtoupper($day->format('d')+543);
echo "|";
}

$s = '';
foreach ($days as $day) {
if ($s) $s .= '|';
$s .= strtoupper($day->format('d')+543);
}
echo $s;
|$n = iterator_count($days);
foreach ($days as $i => $day) {
echo strtoupper($day->format('d')+543);
if (($i+1) != $n) echo '|';
}
$s = array();
foreach ($days as $day) {
$s[] = strtoupper($day->format('d')+543);
}
echo implode('|', $s);
| (或 rtrim 它)$s = '';
foreach ($days as $day) {
$s .= strtoupper($day->format('d')+543) . '|';
}
echo substr($s, 0, -1);
# echo rtrim($s, '|');
