Object of class DateTime could not be converted to string

Question

I have a table with string values in the format of Friday 20th April 2012 in a field called Film_Release

I am looping through and i want to convert

Answer 1

Because $newDate is an object of type DateTime, not a string. The documentation is explicit:

Returns new DateTime object formatted according to the specified format.

If you want to convert from a string to DateTime back to string to change the format, call DateTime::format at the end to get a formatted string out of your DateTime.

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