Are there any specific PHP functions or methods that can simplify the process of converting date formats for database storage?

When storing dates in a database, it's important to ensure that the date format is consistent and compatible with the database's requirements. PHP provides the `date()` and `strtotime()` functions that can be used to convert date formats easily. By using these functions, you can convert dates to the desired format before storing them in the database.

// Example of converting date format for database storage
$date = "2022-01-15";
$formatted_date = date("Y-m-d", strtotime($date));
echo $formatted_date; // Output: 2022-01-15
