O bien, de XDebug:
http://xdebug.org/docs/all_settings Cita: xdebug.scream
Type: boolean, Default value: 0, Introduced in Xdebug 2.1
If this setting is 1, then Xdebug will disable the @ (shut-up) operator so that notices, warnings and errors are no longer hidden.
Pero, eso sólo ocultará el notice.. es un error_reporting, no quitará el fallo (si lo hay)
