我在错误日志中运行php时出现以下错误：
PHP致命错误：在a上调用成员函数setTimezone（） 非对象 /var/www/vhosts/*********.gr/httpdocs/protected/TemplateGenerator.php 在第525行
这是php：
// $val1 = "28/02/2015 18:00";
$date1 = DateTime::createFromFormat('d/m/y H:i', $val1, new DateTimeZone('Europe/Athens'));
$date1->setTimezone(new DateTimeZone('Europe/Athens'));
// $current_month = $date1->format('m');
// $datetime1 = new DateTime($date);
$now = new DateTime();
$now->setTimezone(new DateTimeZone('Europe/Athens'));
$days = (int) $now->diff($date1)->days;
$hours = (int) $now->diff($date1)->format("%H");
// $date1->format(DateTime::ISO8601)
我找不到任何与php相关的错误。 有什么帮助吗？
编辑：$ val1 = $ date。＆＃34; ＆＃34; 。 $时间;

答案 0 :(得分：0)
你已经注释掉了$ val1，因此将此变量设置为undefined并导致DateTime返回false。
答案 1 :(得分：0)
首先，您的$ val1已被注释掉，其次是您的日期格式与该值不匹配。
如果您有四位数年份，则必须使用格式中的大写字母Y.
答案 2 :(得分：0)
电话：
DateTime::createFromFormat('d/m/y H:i', $val1, new DateTimeZone('Europe/Athens'));
返回NULL，因为$val1的值为"28/02/2015 18:00"。
$val1中的年份以4位数字2015表示，但传递给DateTime::createFromFormat()的格式表明它必须是2位数字（小写 y ）。这就是DateTime::createFromFormat()返回NULL。
使用d/m/Y H:i（大写 Y ）作为格式，它会起作用。
$val1 = "28/02/2015 18:00";
$date1 = DateTime::createFromFormat('d/m/Y H:i', $val1, new DateTimeZone('Europe/Athens'));
print_r($date1);
输出结果为：
DateTime Object
(
[date] => 2015-02-28 18:00:00.000000
[timezone_type] => 3
[timezone] => Europe/Athens
)
