PHP Curl上传文件，带文件浏览按钮

I want to remote upload my file into a server that accept uploads using curl , but without typing the full file path every time with "@" symbol can i make a browse button to select files then proceed to curl upload

this is my code ::

$post = array("file_box"=>"@/path/to/myfile.jpg");

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://remote-site");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post); 
$output = curl_exec($ch);
curl_close($ch);

return $output;

just want to change "@/path/to/myfile.jpg" by browse button which passes it's value to php variable

I want to change this [[ $post = array("file_box"=>"@/path/to/myfile.jpg"); ]]

to something like that

[[ $post = array("file_box"=>"@".$variable_contains_file_path_from_browse_button); ]]

to prevent upload the file to middle server(host this script) in the temp path just from the client to the remote server directly

is there any solutions around this

thanks all for any help.
