Solution to the problem when php curl post

$data = array( 'Title' => $title, 'Content' => $content, 'ComeFrom' => $comefrom );
curl_setopt($ch, CURLOPT_DNS_USE_GLOBAL_CACHE , false);
curl_setopt($ch, CURLOPT_URL, 'http://example.com/b.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch);

Send the data to be submitted in the form of an array through POST, and this will cause CURL to use the "wrong" encoding "multipart/form-data", which The effect is equivalent to directly completing the operation with a form like "

". You can try it. At this time, "b.php" cannot receive data through $_POST anyway.

So, the correct approach should be to change $data in the above code from an array to one encoded by urlencode().
