How to Convert DateTime to String?
提问by Jeremy Harris
I have an array of DateTime objects and need to use them as strings in a function call. I have tried casting it like $string_datetime = (string)$myDateTimeObject;but that doesn't work. Searching has been unfruitful as well, as most people are asking how to convert a string to DateTime instead.
我有一个 DateTime 对象数组，需要在函数调用中将它们用作字符串。我试过像这样铸造它，$string_datetime = (string)$myDateTimeObject;但这不起作用。搜索也没有结果，因为大多数人都在问如何将字符串转换为 DateTime。
My Code:
我的代码：
$start_date = new DateTime();
$end_date = new DateTime();
$end_date = $end_date->modify('+1 day');
// Add time range to request
$request['time_range'] = Array ( 'start' => $start_date,
'end' => $end_date);
When calling a function which expects a string (it's an API call) I receive this error:
当调用一个需要字符串的函数（它是一个 API 调用）时，我收到这个错误：
Catchable fatal error: Object of class DateTime could not be converted to string
可捕获的致命错误：无法将 DateTime 类的对象转换为字符串
What's the correct way of converting/extracting a string from a DateTime object?
从 DateTime 对象转换/提取字符串的正确方法是什么？
