在html上传中需要指定

<input type="file" name="media" id="file">

那么在curl上传文件我该怎么设置其name值为media呢?

<?php
    $ch=curl_init('https://api.weixin.qq.com/cgi-bin/media/upload?access_token=123456&type=image');    
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,
        array('name'=>'media','media'=>'@E:\WWW\6\0604\1.jpg')
    );
    $data=curl_exec($ch);
    curl_close($ch);
    echo $data;
?>
