With this function you can get the number of weeks between two dates. This value is always positive, and incomplete weeks will be returned as a fraction.
date_week_span(date1, date2);
| Argument | Type | Description |
|---|---|---|
| date1 | Datetime | The first datetime. |
| date2 | Datetime | The datetime to compare it to. |
diff = date_week_span( date_create_datetime( 2011, 9, 15, 11, 4, 0 ), date_current_datetime() );
This would set "diff" to the number of weeks between 15th September 2011, 11:04.0 and the current date and time.
