This has a common but serious mistake - you're claiming to be an HTTP/1.1
client, but you haven't implemented Chunked transfer encoding. This is a
mandatory requirement for HTTP/1.1 clients, and it's quite common that servers
use it. If you don't handle it, the data will appear to be "corrupted".
The other solutions you posted use PHP's built-in HTTP user agent code, which
does handle this encoding correctly. Alternatively the code above could be
changed to use HTTP/1.0.
