PHP uses CURL to download files

PHP uses CURL to upload files. it is very convenient to use curl to upload files. no headers or post strings are generated. use fsockopen to write a bunch of curls: $ file = array ("upimg" = & gt; "@ E:/png.png"); // file path. add @ before, indicating that PHP uses CURL to upload files.
It is very convenient to upload files using curl. no headers or post strings are generated. you need to write a bunch of data using fsockopen.
Curl:

$ File = array ("upimg" => "@ E:/png.png"); // file path. add @ in front to indicate file upload. $ curl = curl_init ("http: // localhost/. php "); curl_setopt ($ curl, CURLOPT_POST, true); curl_setopt ($ curl, CURLOPT_POSTFIELDS, $ file); curl_exec ($ curl );

Fsockopen

$ UploadFile = file_get_contents ("E:/png.png"); $ boundary = md5 (time (); $ postStr. = "--". $ boundary. "\ r \ n"; // start with the boundary. Note that by default, two more '-' $ postStr than the boundary defined by the header. = "Content-Disposition: form-data; name = \" upimg \ "; filename = \" E:/png.png \ "\ r \ n"; $ postStr. = "Content-Type: image/png \ r \ n"; $ postStr. = $ uploadFile. "\ r \ n"; $ postStr. = "--". $ boundary. "\ r \ n"; // fwrite ($ fp, "POST/. php HTTP/1.0 \ r \ n "); fwrite ($ fp," Content-T Ype: multipart/form-data; boundary = ". $ boundary. "\ r \ n"); fwrite ($ fp, "Content-length :". strlen ($ postStr ). "\ r \ n"); fwrite ($ fp, $ postStr); while (! Feof ($ fp) {echo fgets ($ fp, 128);} fclose ($ fp); print_r ($ _ FILES );

1 floor pz9042 2011-10-24 I would like to ask, can curl Upload FILES? according to your code, print $ _ FILES at the specified url, there is indeed information,, I couldn't find a file in the so-called temporary folder, and I was unable to upload the file. I hope you can post the main code. your current code is just filled in with information, no uploaded code
