How to simulate browser form POST method using PHP/cURL
- by user283266
I'm trying to simulate browser with POST method using PHP/cURL.
When I looked at that live Http header it shows Content-Type: multipart/form-data.
I checked on the internet where it was suggested that cURL will send multipart/form-data when a custom headers is specified to Content-Type: multipart/form-data.
$headers = array(
'Content-Type' => 'multipart/form-data; boundary='.$boundary
);
This didn't work for me either when I print_r(curl_getinfo()) it showed
[content_type] => text/html; charset=UTF-8
Which means cURL sent a default headers
I also read that sending/uploading a file with cURL will cause data to be send as multipart/form-data. I created a file which curl uploaded but again when I ran curl_getinfo I got [content_type] => text/html; charset=UTF-8
$data_array = array("field" => "@c:\file_location.txt");
I also tried to read a file content so that the only thing sent would be content NOT ATTACHED FILE but this didn't work for me curl_getinfo shows [content_type] => text/html; charset=UTF-8.
$data_array = array("field" => "<c:\file_location.txt"); // note @ replaced with <
Do I miss somthing here?
