Definisce il livello di restituzione di errore di PHP e ritorna il vecchio
|
|
livello. Il livello di restituzione dell'errore può essere una maschera di
|
|
bit o una costante named. L'utilizzo delle costanti named è caldamente
|
|
consigliato per assicurare la compatibilità con versioni future.
|
|
All'aggiungere di livelli di errore, la gamma degli interi viene incrementata,
|
|
perciò vecchi livelli di errore basati sull'intero non si comporteranno
|
|
sempre come ci si aspetta.
