(PHP 5)
idate — Format a local time/date as integer
Beschreibung
Returns a number formatted according to the given format string using the given integer timestamp or the current local time if no timestamp is given. In other words, timestamp is optional and defaults to the value of time().
Unlike the function date(), idate() accepts just one char in the format parameter.
Parameter-Liste

Der optionale Parameter timestamp ist ein UnixTimestamp als integer oder die aktuelle lokale Zeitwenn kein timestamp übergeben wurde. Er entsprichtdann also dem Ergebnis der Funktiontime().
Rückgabewerte

As idate() always returns an integer and as they can't start with a "0", idate() may return fewer digits than you would expect. See the example below.
