| DateTime modify | ( | $s, | |
| int | $m = 0, |
||
| int | $h = 0, |
||
| int | $D = 0, |
||
| int | $M = 0, |
||
| int | $Y = 0 |
||
| ) |
Applies date-time modifiers.
$s can be a DateInterval or DateInterval description (e.g. "+1 day"). If so, the rest of the arguments are ignored.
Note: Modifiers are processed from greatest-to-least interval scope, meaning years are applied first and seconds are applied last.
| int | string | DateInterval | $s | Seconds, or DateInterval related |
| int | $m | Minutes |
| int | $h | Hours |
| int | $D | Days |
| int | $M | Months |
| int | $Y | Years |
| DateTime setDate | ( | int | $day = null, |
| int | $month = null, |
||
| int | $year = null |
||
| ) |
Manually set the date components, preserving the time.
NULL can be given to preserve a component's value.
| null | int | $day | |
| null | int | $month | |
| null | int | $year |
| DateTime setTime | ( | int | $seconds = null, |
| int | $minutes = null, |
||
| int | $hours = null |
||
| ) |
Manually set the time components, preserving the date.
NULL can be given to preserve a component's value.
| null | int | $seconds | |
| null | int | $minutes | |
| null | int | $hours |
| DateTime toUTC | ( | string | $mysqlLocalTz = null | ) |
Changes the timezone from local to UTC.
SQLite uses the system's timezone as the "local" timezone, whereas MySQL allows you to specify it.
Warning: Datetimes are already stored and retrieved as UTC. Only use this if you know the expression is in the local timezone.
Warning: Chaining this multiple times will further change the timezone offset.
| null | string | $mysqlLocalTz | The "local" timezone name or offset given to MySQL. Defaults to PHP's current timezone. |
