Beskrivelse
Denne funktion er EKSPERIMENTABEL. Virkemåden af denne funktion, navnet på funktionen, og andet ellers dokumenteret om denne funktion, ændres muligvis uden advarsel i en fremtidig version af PHP. Brug af denne funktion er på ejet ansvar.
Returns the old value for the changed property. This can be used by a Data Access Service when writing updates to a data source. The DAS uses the old value to detect conflicts by comparing it with the current value in the data source. If they do not match, then the data source has been updated since the data object was originally populated, and therefore writing any new updates risks compromising the integrity of the data.
