Php+curl uploading files to a remote server

One, window under the installation of Php_curl support

1. Php_curl.dll the three files under the PHP installation folder (possibly in the Ext folder), Libeay32.dll,ssleay32.dll copy to%windir%/system32;
2. Open PHP.ini (may be in the installation directory of the PHP environment, by default in the C:\WINDOWS directory), the Extension=php_curl.dll head of the semicolon removed;

3. Restart the PHP service (Apache or IIS), such as restarting IIS and running IISRESET.

Second, attention matters.

Note the permissions for the server folder,

PHP.ini Upload_tmp_dir setting up a new directory also gives everyone read and write access.

The target directory for uploading files also gives everyone read and write access.

Third, directly on the code

1. File curltest.php:

  0, ' message ' = ' OK ');        Ini_set (' upload_max_filesize ', ' 20M ');        Ini_set (' post_max_size ', ' 20M ');        Ini_set (' Memory_limit ', ' 128M '); Receive the uploaded remote address $url = isset ($_post[' url ')?               Trim ($_post[' url '): ';        $url = "www.123.com/k1/upload.php";            if (empty ($url)) {$result [' code '] = 40001;            $result [' message '] = ' url cannot be empty ';        Helper_http::writejson ($result);        } $file = $_files[' file '];        Print_r ($_files);            if ($file [' ERROR ']! = 0) {$result [' code '] = 40001;            $result [' message '] = ' upload error ';            Helper_http::writejson ($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 upload file *     * @param unknown $url * @param unknown $filename * @param unknown $path * @param unknown $type * *    function Upload_file ($url, $filename, $path, $type) {echo 3;        echo $path; PHP 5.5 Usage if (class_exists (' \curlfile ')) {$data = array (' file ' = ' = ' = ' = ' = ' = ' = ') ' (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; }?>

2, file upload. php:

 
  "; Print_r ($_files);  $uploaddir = ' d:/temp/caches/'; $uploadfile = $uploaddir. basename ($_files[' file ' [' name ']);  Echo '
'; 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's some more debugging info: ';?>
