当我在Windows:上对WAMP服务器中的文件夹使用fopen时，权限被拒绝
# open file to write
$fp = fopen ($path, 'w+');
# start curl
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $url );
# set return transfer to false
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, false );
curl_setopt( $ch, CURLOPT_BINARYTRANSFER, true );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );
# increase timeout to download big file
curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, 10 );
# write data to local file
curl_setopt( $ch, CURLOPT_FILE, $fp );
# execute curl
curl_exec( $ch );
# close curl
curl_close( $ch );
# close local file
fclose( $fp );
请这样尝试，我已经检查了WAMP，希望这对你有用。
在DiwanOnline文件夹中创建文件并像这样使用。。
$path = $_SERVER['DOCUMENT_ROOT']."''DiwanOnline''testfile.txt";
# open file to write
$fh = fopen($path,'w');

$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt ($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt ($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_URL, $URL);
curl_setopt ($ch, CURLOPT_TIMEOUT, 120);
curl_setopt ($ch, CURLOPT_FILE, $fh);
curl_exec ($ch);
curl_close ($ch);
fclose($fh);

啊。。。您试图打开文件夹而不是文件
请修复
