如何在 PHP 中将 DateTime 对象转换为字符串？

Converting DateTime Objects to Strings

When encountering the error "Object of class DateTime could not be converted to string," it's important to understand that the object being processed is not a string, but rather an instance of the DateTime class.

To resolve this issue, the conversion process needs to be adjusted. Instead of directly inserting the DateTime object into the target table, a string representation of the date must be obtained first. This can be achieved using the DateTime::format() method.

For instance, if the expected format for the Films_Date column is "d/m/Y," the code can be modified as follows:

$newDate = DateTime::createFromFormat("l dS F Y", $dateFromDB);
$stringDate = $newDate->format('d/m/Y');

// Insert $stringDate into the table using an insert command

By explicitly converting the DateTime object to a string, the error will be resolved and the data can be inserted into the target table correctly.
