curl error detection

Hi guys

i am getting a file trough CURL and want to put up some kind of a success indicator to show if the file has been successfully downloaded or not

here's my CURL logic

$ch = curl_init("http://www.domain.com/getthis.zip");
$fp = fopen("savehere.zip", "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);

PHP:

now i want to put something like

if (success_logic_here) {
$success = 1;
}

PHP:

in the middle of this code ..

I know that i could have written something like

if (file_exists("savehere.zip")) { $success = 1;}

PHP:

but thats a kind of ugly way to do it .. why torture the file system if there's possibility to just check on CURL ..

so which part of the CURL determines if it's successfull or not ?

Thanks

 

www.php.net/curl_error

And this can be useful too.

www.php.net/curl_getinfo

 

seems a good idea the curl_error()

any idea if that should be BEFORE or AFTER the curl_close($ch); ?

 

Before. The cURL handle variable will be unset with curl_close(), and you need it for both of the functions above.
