什么是PHP curl等同于命令行curl？

Question

I've tested this command with curl in the command prompt and it works and does what I want it to do.

curl -T filetoupload.tmp http://example.com -H "Accept: text/html" -H "Content-type: appliction/pdf" > filename.htm

I've then tried to express this in php(I run PHP v5.5) and wrote this code, but the remote server doesn't like it so it obviously isn't doing the same thing.

$ch = curl_init("http://example.com"); 
$cfile = curl_file_create('filetoupload.tmp', 'application/pdf', 'filename');
$data['file'] = $cfile;
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
  'Content-type: application/pdf',
  'Accept: text/html'
));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

what am I doing wrong?

curl -T filetoupload.tmp uploads the file as the RAW post body. Your PHP code is sending the file with headers, like you were posting a form with multipart/form-data .

You need to set the raw post body in your PHP code. Also, it looks like curl -T uses PUT instead of POST .

$ch = curl_init("http://example.com"); 
$file = fopen('filetoupload.tmp', 'r');
curl_setopt($ch, CURLOPT_INFILE, $file);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize('filetoupload.tmp'));
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
  'Content-type: application/pdf',
  'Accept: text/html'
));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
fclose($file);
