Curl: Saving a file instead of opening it

Question

I'm calling an API that sends me this response:

...
... (etc)

If I use this code the file is sent to the user and everything works fine:

list($headers, $content) = explode("\r\n\r\n", $result ,2);
foreach (explode("\r\n",$headers) as $header)
{
    header($header);
}

//return the nonheader data
return trim($content);

But now, I would like to save the file somewhere else so my script can work on it (rename it etc), so I don't want to directly send it to the user.

I've tried to comment the header($header); part, and do something like:

$content = getMyFile();
$file = fopen('MYTEST.docx', "w+");
fputs($file, $content);
fclose($file);

But the resulting file is not readable (it seems to be corrupted).

Do you have any idea of what could cause this problem?

Thanks in advance.

Answer 1

You need to specify content length for fputs for it to be binary safe.

In this case you could try fputs($file, $content, 68720);

And ultimately provide the length from the header.

Also I would suggest opening file in binary mode by using fopen('MYTEST.docx', "wb"); especially in case you are running your code on Windows.
