Hello,

i am trying to retrieve binary content of a bytea field (or postgis =
geometry field) with a binary cursor with PHP :

$sql=3D"BEGIN;DECLARE mycursor BINARY CURSOR FOR SELECT shape FROM =
$layerName; fetch all in mycursor;"
.....pg_query...=20

But my shape field shows only two bytes of data.
=20
Does someone know if it is a current PHP restriction ?

Thanks by advance,

Eric
