Getting a file pointer from file descriptor

Question

In PHP 5.2.3, "fdopen" was used to read/write to a file descriptor that's opened by another application.

fdopen(<fileDescriptorId>,"rw");  //It worked fine with PHP 5.2.3

After upgrading PHP to 5.3.2, it's throwing "undefined reference to 'fdopen' function".

Please suggest whats the replacement for this in PHP 5.3.2 or any workaround.

Answer 1

The fdopen is related to C language. There is no such function in PHP. I think you have mis-typed the PHP's fopen function, right? Correct me. Thanks

Answer 2

Could this fdopen() of yours have been provided by a custom php extension?
On a linux/unix server

function fdopen($id, $mode) {
  return fopen("/proc/self/fd/".(int)$id, $mode);
}

might work.
