hw_getremotechildren - Gets children of remote document

SYNOPSIS

       mixed hw_getremotechildren (int	$connection, string  $object_record)

DESCRIPTION

	Returns the children of a remote document. Children of a remote document are remote documents itself. This makes sense if a database query
       has to be narrowed and is explained in Hyperwave Programmers' Guide.

	If you want to use this function you should be very familiar with HGIs. You should also consider to use PHP instead of Hyperwave to access
       external sources. Adding database support by a Hyperwave gateway should be more difficult than doing it in PHP.

PARAMETERS

	      o $connection
		- The connection identifier.

	      o $object_record
		- The object record.

RETURN VALUES

	If  the  number  of  children is 1 the function will return the document itself formatted by the Hyperwave Gateway Interface (HGI). If the
       number of children is greater than 1 it will return an array of object record  with  each  maybe  the  input  value  for  another  call	to
       hw_getremotechildren(3).  Those	object	records  are  virtual and do not exist in the Hyperwave server, therefore they do not have a valid
       object ID. How exactly such an object record looks like is up to the HGI.

pg_lo_import - Import a large object from file

SYNOPSIS

       int pg_lo_import ([resource  $connection], string  $pathname, [mixed  $object_id])

DESCRIPTION

       pg_lo_import(3) creates a new large object in the database using a file on the filesystem as its data source.

	To use the large object interface, it is necessary to enclose it within a transaction block.

       Note

	      When  safe  mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script
	      that is being executed.

       Note

	       This function used to be called pg_loimport(3).

PARAMETERS

	      o $connection
		- PostgreSQL database connection resource. When $connection is not present, the default connection is used. The default connection
		is the last connection made by pg_connect(3) or pg_pconnect(3).

	      o $pathname
		- The full path and file name of the file on the client filesystem from which to read the large object data.

	      o $object_id
		-  If an $object_id is given the function will try to create a large object with this id, else a free object id is assigned by the
		server. The parameter was added in PHP 5.3 and relies on functionality that first appeared in PostgreSQL 8.1.

RETURN VALUES

	The $OID of the newly created large object, or FALSE on failure.
