一、window下安装php_curl支持
1.将PHP安装文件夹下的三个文件php_curl.dll(可能在ext文件夹中),libeay32.dll,ssleay32.dll 复制到 %windir%/system32下; 2.打开php.ini(可能在PHP环境的安装目录下，默认在c:\WINDOWS目录下)，将;extension=php_curl.dll头部的分号去掉;
3.重启php的服务(apache或者IIS)，如重启IIS，运行iisreset即可。
二、注意事项。
注意服务器文件夹的权限，
php.ini里upload_tmp_dir设置一个全新的目录也赋予Everyone读写权限。
上传文件的目标目录也赋予Everyone读写权限。
三、直接上代码
1、文件curlTest.php:
<form action=" curlTest.php" enctype="multipart/form-data" method="post"> <p>UpLoad: <input type="file" name="file" id="file"/></p> <input type="submit" value="Submit" /></form><?phpupload();/*** 上传图片api**/function upload(){$result = array('code' => 0, 'message' => 'ok');ini_set('upload_max_filesize', '20M');ini_set('post_max_size', '20M');ini_set('memory_limit', '128M');//接收上传的远程地址$url = isset($_POST['url']) ? trim($_POST['url']) : '';$url ="";if (empty($url)) {$result['code'] = 40001;$result['message'] = 'url不能为空';//Helper_Http::writeJson(200,$result);}$file = $_FILES['file'];print_r($_FILES);if ($file['error'] != 0) {$result['code'] = 40001;$result['message'] = '上传出错';//Helper_Http::writeJson(200,$result);echo 1;} else {$filename = $file['name'];$tmpfile = $file['tmp_name'];$filetype = $file['type'];$data = upload_file($url, $filename, $tmpfile, $filetype);echo $data;print_r ($url);die;}}/*** curl上传文件** @param unknown $url* @param unknown $filename* @param unknown $path* @param unknown $type*/function upload_file($url,$filename,$path,$type){echo 3;echo $path;//php 5.5以上的用法if (class_exists('\CURLFile')) {$data = array('file' => new \CURLFile(realpath($path),$type,$filename));} else {$data = array('file'=>'@'.realpath($path).";type=".$type.";filename=".$filename);}echo 'data:';print_R($data);$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_POST, true );curl_setopt($ch, CURLOPT_POSTFIELDS, $data);curl_setopt($ch, CURLOPT_HEADER, false);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);$return_data = curl_exec($ch);curl_close($ch);echo $return_data;}?><?php echo "<pre> "; print_r($_FILES); $uploaddir = 'D:/temp/caches/'; $uploadfile = $uploaddir . basename($_FILES['file']['name']); echo '<pre>'; if (move_uploaded_file($_FILES['file']['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:'; ?>
