Convert DateTime to String PHP
提问by Netorica
I have already researched a lot of site on how can I convert PHP DateTime object to String. I always see "String to DateTime" and not "DateTime to String"
我已经研究了很多关于如何将 PHP DateTime 对象转换为 String 的网站。我总是看到“字符串到日期时间”而不是“日期时间到字符串”
PHP DateTime can be echoed, but what i want to process my DateTime with PHP string functions.
PHP DateTime 可以回显，但我想用 PHP 字符串函数处理我的 DateTime。
My question is how can I make PHP dateTime Object to a string starting from this kind of code:
我的问题是如何将 PHP dateTime 对象设置为从这种代码开始的字符串：
$dts = new DateTime(); //this returns the current date time
echo strlen($dts);

You can use the formatmethod of the DateTimeclass:
您可以使用该类的format方法DateTime：
$date = new DateTime('2000-01-01');
$result = $date->format('Y-m-d H:i:s');
If formatfails for some reason, it will return FALSE. In some applications, it might make sense to handle the failing case:
如果format由于某种原因失败，它将返回FALSE。在某些应用程序中，处理失败的情况可能是有意义的：
if ($result) {
echo $result;
} else { // format failed
echo "Unknown Time";
}

The simplest way I found is:
我发现的最简单的方法是：
$date = new DateTime(); //this returns the current date time
$result = $date->format('Y-m-d-H-i-s');
echo $result . "<br>";
$krr = explode('-', $result);
$result = implode("", $krr);
echo $result;
I hope it helps.
我希望它有帮助。

There are some predefined formats in date_d.phpto use with formatlike:
有一些预定义的格式date_d.php可以使用，format例如：
define ('DATE_ATOM', "Y-m-d\TH:i:sP");
define ('DATE_COOKIE', "l, d-M-y H:i:s T");
define ('DATE_ISO8601', "Y-m-d\TH:i:sO");
define ('DATE_RFC822', "D, d M y H:i:s O");
define ('DATE_RFC850', "l, d-M-y H:i:s T");
define ('DATE_RFC1036', "D, d M y H:i:s O");
define ('DATE_RFC1123', "D, d M Y H:i:s O");
define ('DATE_RFC2822', "D, d M Y H:i:s O");
define ('DATE_RFC3339', "Y-m-d\TH:i:sP");
define ('DATE_RSS', "D, d M Y H:i:s O");
define ('DATE_W3C', "Y-m-d\TH:i:sP");
Use like this:
像这样使用：
$date = new \DateTime();
$string = $date->format(DATE_RFC2822);

Its worked for me
它对我有用
$start_time = date_create_from_format('Y-m-d H:i:s', $start_time);
$current_date = new DateTime();
$diff = $start_time->diff($current_date);
$aa = (string)$diff->format('%R%a');
echo gettype($aa);

Shorter way using list. And you can do what you want with each date component.
使用列表的更短方法。您可以对每个日期组件执行您想要的操作。
list($day,$month,$year,$hour,$min,$sec) = explode("/",date('d/m/Y/h/i/s'));
echo $month.'/'.$day.'/'.$year.' '.$hour.':'.$min.':'.$sec;
