How can PHP developers effectively communicate date calculation requirements to ensure accurate results in Oracle databases?

When communicating date calculation requirements to Oracle databases, PHP developers should ensure that they are using the correct date functions and formats that are compatible with Oracle's date handling. It is important to specify the timezone and format of the dates being used to avoid any discrepancies in calculations. Additionally, developers should be aware of any differences in date handling between PHP and Oracle to ensure accurate results. 

// Example of communicating date calculation requirements to Oracle database

$date = '2022-01-15';
$days_to_add = 7;

// Using Oracle's TO_DATE function to convert the date to Oracle format
$oracle_date = date('d-M-Y', strtotime($date));

// Adding days to the date in Oracle
$query = "SELECT TO_CHAR(TO_DATE('$oracle_date', 'DD-MON-YYYY') + $days_to_add, 'DD-MON-YYYY') AS result FROM dual";

// Execute the query and fetch the result
$result = oci_parse($conn, $query);
oci_execute($result);

while ($row = oci_fetch_assoc($result)) {
    echo $row['RESULT'];
}

oci_free_statement($result);
