I've got a tiny bit of code running on my mac dev server that fails with a "couldn't resolve host" error. I've tried typing 'curl http://www.domain.com/file.txt' at the command line and it echoes out the entire file with no problems so I know it's not a network problem. The code looks pretty straightforward:
$csv = 'http://www.domain.com/file.txt';
$tmp_file_name = 'tmp/'.numOnly(microtime(true)).'.txt';
$ch = @curl_init();
$fp = @fopen($tmp_file_name, 'w');
@curl_setopt($ch, CURLOPT_URL, $csv);
@curl_setopt($ch, CURLOPT_FILE, $fp);
@curl_setopt($ch, CURLOPT_FAILONERROR, 0);
@curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 8);
@curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
@curl_setopt($ch, CURLOPT_TIMEOUT, 16);
@curl_setopt($ch, CURLOPT_VERBOSE, 1);
if(@curl_exec($ch) === false){
die(@curl_error($ch));
}else{
echo 'success!';
}
@curl_close($ch);
@fclose($fp);
My curl settings in phpinfo look like this:

Can anyone suggest a good reason why curl would fail when run under apache while it works fine from the command line?
