upload a file to server without using a form?
This is an example of file uploading with cURL you could start with:
$ch = curl_init('http://api.blabla.com/huhu.php');curl_setopt_array($ch, array( CURLOPT_POSTFIELDS => array( 'files[]' => '@/path/to/file', ),));if (false === ($res = curl_exec($ch))) { die("Upload failed: " . curl_error($ch));}The string '@/path/to/file' has a special meaning because it starts with an @; the string that directly follows it should contain the path of a file you wish to upload.
