php a une gestion des exceptions similaire à ce qu'offrent les autres langages de programmation. une exception peut être lancée ("throw") et attrapée ("catch") dans php. le code devra être entouré d'un bloc try pour faciliter la saisie d'une exception potentielle. chaque try doit avoir au moins un bloc catch ou finally
