How to extract the date (Y-m-d) from a DateTime object in PHP?

To extract the date from a DateTime object in PHP, you can use the format() method along with the desired format string. In this case, the date format "Y-m-d" can be used to represent the date in the format "Year-Month-Day".

Here's an example:

$dateTime = new DateTime();  // Create a new DateTime object

$date = $dateTime->format("Y-m-d");  // Extract the date in "Y-m-d" format

echo $date;  // Output: e.g., "2022-01-01"

In this example, the current date and time are stored in the $dateTime object. Then, the format() method is used to extract the date in the desired "Y-m-d" format and store it in the $date variable. Finally, the extracted date is displayed using the echo statement.
