从此代码：
$kw = CalenderWeekHelper::getCalenderWeek($currentYear);
if(isset($_POST['generate'])) {
for($i = 0; $i < 52; $i++) {
foreach($users as $user) {
if ($i > 52) {
break;
}
$start = $kw[$i]['start'];
$end = $kw[$i]['end'];
$startCon = date('Y-m-d', $start);
$endCon = date('Y-m-d', $end);
}
}
}
助手类：
class CalenderWeekHelper {
public static function getCalenderWeek($year)
{
for ($i=0; $i <= 52; $i++)
{
$week = sprintf('%02s', $i);
$from = date("Y-m-d", strtotime("{$year}W{$week}")); # d.m.Y
$to = date("Y-m-d", strtotime("{$year}W{$week} +6 days"));
$weekArray[$i] = array('start' => $from, 'end' => $to);
}
return $weekArray;
}
}
我收到：
注意：在中遇到格式不正确的数值。。。行：
哪个指向这些线：
$startCon = date('Y-m-d', $start);
$endCon = date('Y-m-d', $end);
编辑：var_dump（$kw）打印出以下内容：
array (size=53)
0 =>

有人知道解决方案吗？
date()函数只接受unix时间戳。
在您的代码中，您有两个选项：
1:直接使用$start和$end，因为它们已经格式化好了：
$startCon = $start;
$endCon = $end;
2：使用strtotime():将$start和$end转换为unix时间戳
$startCon = date('Y-m-d', strtotime($start));
$endCon = date('Y-m-d', strtotime($end));
如果要更改格式，请使用第二种格式。如果没有，请使用第一个。
