Le principe est très simple : on entoure le code qui peut potentiellement provoquer une erreur par un bloc try catch, et si une erreur se produit lors de l'exécution du code présent dans le bloc try, PHP va exécuter le code qui se trouve dans le catch, permettant ainsi de gérer l'erreur. The ?try documentation is much better and has a useful example showing how try() can be used to generate simulated results, ignoring those that generated errors. instead of the default stderr(), notably when try() is used inside a Sweave code chunk and the error message should appear in the resulting document.
