上传文件的curl参数是-T：
-T/--upload-file <file> Transfer <file> to remote site     --url <URL>     Spet URL to work with

1）上传uploadContents.txt文件内容：
this is upload file by php.

2）接收代码：
<?php // Example to parse "PUT" requests $contents = file_get_contents('php://input'); echo $contents;echo "\n"; //parse_str(file_get_contents('php://input'), $_PUT); // The result //print_r($_PUT); ?>
来自plupload里通过swf一个文件小于自己配置的10M时就一次性上传的协议，Flash是这样进行提交的：
Content-Disposition: form-data; name="name" p18e57aitdkecp1vbe40lccu4.zip
                                             XXXXXXXXXX 文件内容
3）运行打印：
C:\Users\admin>curl -d"dfd=php://input can not read here's contents"  -T"D:\uploadContents.txt" http://localhost/php_input.php
this is upload file by php.

4）说明，对于-d参数，其PHP的php://input是不会接收的，其接收的是二进制流，用$_POST,是可以打印出来的(但通过linux下的shell同时发送-d -T是只能打出-T内容)。

如，通过给PHP里的php://input上传一个文件，发现这个文件不能被读取到，说明它就是只能接二进制文件的，如下：
C:\Users\admin>curl -F upload_file=@D:\uploadContents.txt -F "name=yangqi" http://localhost/php_input.php
-F/--form <name=content> Specify HTTP multipart POST data (H)
    --form-string <name=string> Specify HTTP multipart POST data (H)
Array
(
    [upload_file] => Array
        (
            [name] => uploadContents.txt
            [type] => text/plain
            [tmp_name] => D:\wamp\tmp\phpDAB9.tmp
            [error] => 0
            [size] => 76
        )

)
Array
(
    [name] => yangqi
)

接收代码如下：
<?php     // Example to parse "PUT" requests     $contents = file_get_contents('php://input');     echo $contents;     echo "\n";     print_r($_FILES);     print_r($_POST); ?>
_______________________分块传时是这样的_______________________________
Content-Disposition: form-data; name="name"  p18e57g55eof2u6k19971jo1cvu8.zip
Content-Disposition: form-data; name="chunk"  0
Content-Disposition: form-data; name="chunks"  5
                                                                       上传文件内容XXXX

更多参考如下Url：http://jackxiang.com/post/6421/
curl -F userfile=@/usr/local/apache2/conf/httpd.conf http://app.space.sina.com.cn/upload.php // 上传
curl -d "get=123&post=222" http://app.space.sina.com.cn/get_post.php   //post
curl http://app.space.sina.com.cn/get_post.php?"post=888&get=1212"   //引号引起来get
加上访问时间（注意：这儿的upload_file相当于控件html file的name）：
curl -s -w '%{time_connect}:%{time_starttransfer}:%{time_total}' -F upload_file=@/home/xiangdong/uploadFileTest/buer.rmvb "http://up.xiyou.cntv.cn/uptest.php"

PHP扩展用Curl上传文件：

$str =   $res['str']; $iplist = $res['iplist']; $did = $res['did']; $handle = fopen("/tmp/hostname.txt","w"); fwrite($handle,$str); fclose($handle); $ret = curlUpload("/tmp/hostname.txt","http://jackxiang.com/php/uploadHostName.php"); $retary = json_decode($ret,true); if($retary['code']==-1){   die("{code:1,msg:\"上传hostname失败\"}"); } @unlink("/tmp/hostname.txt");
调用的实际上传：
/** * curl 上传 */ function curlUpload($filename,$url){   $fields['software'] = '@'.$filename;   $fields['phpcallback'] = true;   $ch = curl_init();   curl_setopt($ch, CURLOPT_URL, $url );   curl_setopt($ch, CURLOPT_POST, true );   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);   curl_setopt($ch, CURLOPT_POSTFIELDS, $fields );   $content =  curl_exec( $ch );   curl_close($ch);   return $content; }


附录Flash进行多文件上传时的代码，在单文件时是通过php:input，而多文件时是_FILES进行分块上传的，upload.php里的代码如下：

"wb" : "ab");     if ($out) {       // Read binary input stream and append it to temp file       $in = @fopen($_FILES['file']['tmp_name'], "rb");       if ($in) {         while ($buff = fread($in, 4096))           fwrite($out, $buff);       } else         die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');       @fclose($in);       @fclose($out);       @unlink($_FILES['file']['tmp_name']);     } else       die('{"jsonrpc" : "2.0", "error" : {"code": 102, "message": "Failed to open output stream."}, "id" : "id"}');   } else     die('{"jsonrpc" : "2.0", "error" : {"code": 103, "message": "Failed to move uploaded file."}, "id" : "id"}'); } else {   // Open temp file   $out = @fopen("{$filePath}.part", $chunk == 0 ?
