Cool, I didn't know that.
Using error suppression is always a bad thing. It makes debugging in the
future much more difficult. If you want to include only files that exist
just wrap it in an if ( file_exists($file) ). This makes the code much more
clearer [sic] and you don't sacrifice missing other potential errors that
include_once might throw.
Aside from the slowness, I don't see how the two are different.
Either way you're ensuring that include_once doesn't screw up your
program.
Essentially, you are acknowledging that there will likely be an error
when including the file. By wrapping the include in a file_exists($file)
function, you are actually handling the error, rather than just ignoring
it. Plus, this way you could have the code do something different if
the file doesn't exist, whereas if you just ignore the error there is no
way for the rest of the script to know whether or not the file was included.
