I'm confused with the conditional inside the if(...)

[php]$_FILES["file"]["error"] // the error code resulting from the file upload-/PHP]

I still don't understand that line... can anybody help me out with this? How can PHP check if there's an error if there's no $_FILES["file"]["error"] that's instantiated to be 0 or > 1 ???? I'm confused

From what i gather,
Means that if there are more than 0 errors, so theres an error in the file then
Show the error.

what do you mean with error in the file? It's checking error WITHIN the file, or error within your PHP codes?

You've got a form with
that submits to your php code. The $_FILES['file']['error'] will contain a number based on whether there was an error. 0 is no error. Look at www.php.net/features.file-upload . It's very clear on how to do this.

I understand that, but I'm just wondering to what exactly this PHP code is checking by putting $_FILES['file']['error'] within the IF conditional statement for example:

I understand exactly what the code above does, which is checking variable $x whther it's bigger or less than 0... so what's $_FILES['file']['error'] is checking? I also understand that it's checking whether there's an error or not, but where? if there's an error within PHP? but where's the error? it's impossible to have an error, since there's nothing to be checked earlier please give me some example, prob help me better thx a lot guys...

from what I am getting from it is that it is checking for errors in the file type, size, ect... and errors with in the php script,,, as far as I can see

Edit:
Hhmmm well forget this post I posted at the sime time the post above was posted

do you even know PHP upload before you're talking about these? If that's the only line that can check all of those, then what's the point of having $_FILES['file']['size'] and $_FILES['file']['type'] ???

The only thing I know about uploading is at the following:
PHP File Upload

just thought I would state my thoughts...

that's because you don't know it, that's why you said that's the only thing that you know about uploading. I'm giving you example from that website too.. omg...

I am 99% sure that line checks for an error within the file, for PHP to do something as its server side the file must first be uploaded, if the file is corrupt it will say that theres an error in the file and why that is so, otherwise its going to show the statistics of the file such as its name/size etc...

The name and size and other things like that can be used to make restrictions or checks, like when a file is uploaded if you only want to allow a certain size then you would use that value to compare against the size you want and choose where to go from there.
