[实践OK]用 curl上传文件，Linux的Shell下用CURL上传文件实例于php://input的接收，PHP扩展用Curl上传文件。

上传文件的curl参数是-T：

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

2）接收代码：

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 Specify HTTP multipart POST data (H)
    --form-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：

_______________________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"

0.001:0.001:14.458

$uploaddir = '/home/xiangdong2/pic_all_here';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile))
{
    echo "File is valid, and was successfully uploaded.\n";
} else {
            echo "Possible file upload attack!\n";
            echo 'Here is some more debugging info:';
            print_r($_FILES);

       }

?>

upload file

if(isset($_REQUEST['get']))
{
    $get =$_REQUEST['get'];
}else{
$get="get";

}
if(isset($_REQUEST['post']))
{
    $post =$_REQUEST['post'];
}else{

    $post="post";
}

echo "get=".$get."\n";
echo "post=".$post."\n";

?>

PHP扩展用Curl上传文件：

调用的实际上传：

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：
