Curl command to simulate form upload file

Initialization $ch = Curl_init (); To upload the local file address "@f:/xampp/php/php.ini" upload time, the upload path must be preceded by the @ symbol $furl = "@f:/xampp/php/php.ini"; $post _data = Array ( "Upload" = $furl ); Where does curlopt_url mean to submit? Corresponds to the path specified by "Action" in the form $url = "http://localhost/test/curl/curl_post.php"; Setting variables curl_setopt ($ch, Curlopt_url, $url); curl_setopt ($ch, Curlopt_returntransfer, 0);//Whether the execution result is returned, 0 is returned, and 1 is not returned curl_setopt ($ch, Curlopt_header, 0);//parameter settings, whether the header information is displayed, 1 is displayed, 0 is not displayed Forge a webpage source address and forge a form submission from Baidu curl_setopt ($ch, Curlopt_referer, "http://www.baidu.com"); form data, is the normal form setting value is not 0 curl_setopt ($ch, Curlopt_post, 1); curl_setopt ($ch, curlopt_timeout, 1);//Set the maximum amount of curl execution time-out When using arrays to provide post data, the Curl component is presumably intended to be compatible with the @filename of this upload file. By default the Content_Type is set to Multipart/form-data. Although for most Web servers and No impact, but there are still a few servers that are incompatible. This article concludes that there is no need to upload files in the case, try to http_build_query the data submitted by the post, and then send it out, to achieve better compatibility, smaller request packets. curl_setopt ($ch, Curlopt_postfields, $post _data); Execute and get results $output = curl_exec ($ch); if ($outopt = = = FALSE) { echo " "," CUrl Error: ". Curl_error ($ch); } Releasing the curl handle Curl_close ($ch); ?> Copy Code File 2:curl_post.php echo " "; Var_dump ($_files); ?> Copy Code The results are as follows: Array (1) { ["Upload"]=> Array (5) { ["Name"]=> String (7) "PHP.ini" ["Type"]=> String ("Application/octet-stream") ["Tmp_name"]=> String ("F:xampptmpphpb2d1.tmp") ["Error"]=> Int (0) ["Size"]=> Int (46217) } } Copy Code
