Error trapping getaddrinfo - File not found v. Temporary failure in name resolution?

[Kronalias]

Hi - could a guru please help?

I'm trying to trap errors when I try to load a url into an array. I can
trap all errors by using this code:

if ( @file($url) == false ){
got a problem;
}

.... but then I don't know whether the problem is that the url file
doesn't exist, or whether it's just a temporary failure in name
resolution.

1. Is there a way to find out what the problem is?

2. I apologise for this question, and my only defence is that I'm a
newbie! Could someone please explain what the '@' in my code above
does? I've been rtfming and googling until I'm blue in the face, but I
can't figure it out...

Thanks in advance for not yelling at me...

Regards, Kronalias

You can probably see what the problem is by setting
error_reporting (E_ALL) and removing the @ sign which is used to
suppress error messages. More info on the error suppression operator:
