//If the php file is utf8 encoded and the system is GBK encoded, then you need to change the encoding, otherwise Php cannot find this file in the system
$ file = realpath(mb_convert_encoding('Test image.JPG','GBK','utf8'));

$file = realpath('temp.jpg'); //File to be uploaded
$fields['f' ] = '@'.$file; // Add the @ symbol in front to indicate uploading pictures

$ch =curl_init();


curl_setopt($ch,CURLOPT_URL,'http://localhost/upload.php'); ECurl_Setopt ($ ch, curlopt_post, true); Rue); c $ content = curl_exec ($ ch);
