 * element is the descriptor type and the second element is an option for
 * the given type. Valid types are pipe (the second
 * element is either r to pass the read end of the pipe
 * to the process, or w to pass the write end) and
 * file (the second element is a filename).
 * A stream resource representing a real file descriptor (e.g. opened file,
 * a socket, STDIN).
 * </p>
 * <p>
 * The file descriptor numbers are not limited to 0, 1 and 2 - you may
 * specify any valid file descriptor number and it will be passed to the
 * child process. This allows your script to interoperate with other
 * scripts that run as "co-processes". In particular, this is useful for
 * passing passphrases to programs like PGP, GPG and openssl in a more
 * secure manner. It is also useful for reading status information
 * provided by those programs on auxiliary file descriptors.
 * </p>
 * @param array &$pipes <p>
 * Will be set to an indexed array of file pointers that correspond to
 * PHP's end of any pipes that are created.
 * </p>
 * @param string|null $cwd [optional] <p>
 * The initial working dir for the command. This must be an
 * absolute directory path, or null
 * if you want to use the default value (the working dir of the current
 * PHP process)
 * </p>
 * @param array|null $env_vars [optional] <p>
 * An array with the environment variables for the command that will be
 * run, or null to use the same environment as the current PHP process
 * </p>
 * @param array|null $options [optional] <p>
 * Allows you to specify additional options. Currently supported options
 * include:
 * suppress_errors (windows only): suppresses errors generated by this
 * function when it's set to TRUE
 * generated by this function when it's set to true
 * bypass_shell (windows only): bypass cmd.exe shell when set to TRUE
 * context: stream context used when opening files
 * (created with stream_context_create)
 * blocking_pipes: (windows only): force blocking pipes when set to TRUE
 * create_process_group (windows only): allow the child process to handle
 * CTRL events when set to TRUE
 * create_new_console (windows only): the new process has a new console,
 * instead of inheriting its parent's console
 * </p>
 * @return resource|false a resource representing the process, which should be freed using
 * proc_close when you are finished with it. On failure
 * returns false.
