About Curl Analog upload files

There is a small problem when using curl to simulate uploads, so write it down: set up forms in curl, including files uploaded online a lot of it.

$post _data = Array (
        "file" => "@". "Path where the file is located"
    );

 $ch = Curl_init ();
 curl_setopt ($ch, Curlopt_httpheader, explode ("\ r \ n", $header))//Analog header 
 curl_setopt ($ch, Curlopt_ Returntransfer, true);
 curl_setopt ($ch, Curlopt_url, $url); 
 curl_setopt ($ch, Curlopt_post, true); 
 curl_setopt ($ch, Curlopt_timeout, $time _out); 
 curl_setopt ($ch, Curlopt_cookie, $cookie);
 Post Data
 curl_setopt ($ch, Curlopt_postfields, $post _data);

 $result = curl_exec ($ch);
 $info = Curl_getinfo ($ch);
 

But I found out that I couldn't accept the file $_files this parameter array:
Then Baidu looked at the original php5.5 can be used before the use of this, PHP5.5 after the use of a

To pass the parameters:

$post _data[' file '] = new Curlfile (Realpath ($file _path), $mime _type, $file _name);

The MIME type of a file can be evaluated based on the following function:

function _getmimedetect () {if (class_exists (' Finfo ')) {return ' finfo ';
        else if (function_exists (' Mime_content_type ')) {return ' Mime_content_type ';
            else if (function_exists (' exec ')) {$result = exec (' File-ib '. Escapeshellarg (__file__));
            if (0 = = Strpos ($result, ' text/x-php ') | | 0 = = Strpos ($result, ' text/x-c++ ')) {return ' Linux ';
            $result = EXEC (' File-ib '. Escapeshellarg (__file__));
            if (0 = = Strpos ($result, ' text/x-php ') | | 0 = = Strpos ($result, ' text/x-c++ ')) {return ' BSD ';
    } return ' internal '; function _getmimetype ($path) {$mime = array (//applications ' ai ' => ' application
