How to Resolve the \'Object of class DateTime could not be converted to string\' Error?

Unveiling the Conversion Conundrum: DateTime Object Conversion to String

In the realm of data manipulation, you encounter situations where converting values between different formats is crucial. When working with date and time values stored as strings, the task of converting them to DateTime objects for further operations and insertions into a database often arises. However, an unexpected error may surface during this process: "Object of class DateTime could not be converted to string."

To comprehend the cause of this error, it's imperative to recognize that the outcome of DateTime::createFromFormat is not a string but a DateTime object. As the documentation explicitly states, this method returns "new DateTime object formatted according to the specified format."

To resolve this issue and successfully insert your date values into a table, you must explicitly convert the DateTime object back into a string. This can be achieved by calling the DateTime::format method, which accepts a format string specifying the desired output format.

For instance, if you wish to change the format of your DateTime object $newDate from "l dS F Y" to "d/m/Y," you would execute the following code:

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

By employing this approach, you effectively rectify the error by converting your DateTime object into a string that can be stored in your database column. This step ensures seamless data manipulation and successful insertions into your desired table.
