It's an error suppressor, if the following function creates an error it'=
s =
nor reported. You should almost never need this, often it's a sign of =
sloppy code when it's littered with @'s. On a live server, offcourse you=
=
don't want to display the errors to your poublic, that's why we have the=
=
setting 'display_errors', which you can set to false.
In this case, instead of:
$za_dir =3D @dir(DIR_WS_INCLUDES . 'extra_configures');
THe author should have:
if(!is_dir(DIR_WS_INCLUDES . 'extra_configures')){
//do some error handling
return false;
}
$za_dir =3D dir(DIR_WS_INCLUDES . 'extra_configures');
