PHP DateTime __construct() Failed to parse time string (xxxxxxxx) at position x
提问by Alex
I had this construction error when trying to creating a new DateTime object using a timestamp:
尝试使用时间戳创建新的 DateTime 对象时出现此构造错误：
Exception: DateTime::_construct(): Failed to parse time string (1372622987) at position 8 (8): Unexpected character in DateTime->_construct()
异常：DateTime::_ construct()：无法解析位置 8 (8) 处的时间字符串 (1372622987)：DateTime->_construct() 中出现意外字符
The object creation code is:
对象创建代码为：
$start_date = new DateTime( "@{$dbResult->db_timestamp}" );
Where $dbResult->db_timestamp is a valid unix timestamp taken from a database. The timestamp in question was:
其中 $dbResult->db_timestamp 是取自数据库的有效 unix 时间戳。有问题的时间戳是：
1372622987
1372622987
I would understand this error for invalid formats being passed, but this is a genuine timestamp.
我会理解传递无效格式的错误，但这是一个真正的时间戳。
The reason this is very strange: I since ran a script to create a new DateTime object with the timestamp passed in as a hard coded value, and it reported no errors.
这很奇怪的原因是：我运行了一个脚本来创建一个新的 DateTime 对象，其中时间戳作为硬编码值传入，并且它没有报告任何错误。
This seems to have been a one off, but I need an explanation if there is one, as I can't afford for this to happen again.
这似乎是一次性的，但如果有的话，我需要一个解释，因为我无法承受再次发生这种情况。

You should use setTimestamp instead, if you hardcode it:
如果您对其进行硬编码，则应改用 setTimestamp：
$start_date = new DateTime();
$start_date->setTimestamp(1372622987);
in your case
在你的情况下
$start_date = new DateTime();
$start_date->setTimestamp($dbResult->db_timestamp);

change your code to this
将您的代码更改为此
$start_date = new DateTime( "@" . $dbResult->db_timestamp );
and it will work fine
它会正常工作
回答by Bastien D
$start_date = new DateTime();
$start_date->setTimestamp($dbResult->db_timestamp);

This worked for me.
这对我有用。
/**
* return date in specific format, given a timestamp.
*
* @param timestamp $datetime
* @return string
*/
public static function showDateString($timestamp)
{
if ($timestamp !== NULL) {
$date = new DateTime();
$date->setTimestamp(intval($timestamp));
return $date->format("d-m-Y");
}
return '';
}
