The problem you are demonstrating is not a problem with the behaviour of multidimensional arrays,
but rather with a misunderstanding of how $array[]=value works. It is essentially equivalent to an
array_push, so when you do
$a[][0]=1;
$a[][1]=2;
$a[][0]=3;
$a[][1]=4;
instead of your desired structure
$a[0] = array(1,2);
$a[1] = array(3,4);
you end up with
$a[0][0] = 1;
$a[1][1] = 2;
$a[2][0] = 3;
$a[3][1] = 4;
thus your foreach loop does not behave as expected. Generally I find it easier in your described
use to just do
while($row = ...fetch_array(...)) {
$myarray[] = $row;
}
thus ending up with an array of hashes. If you really wanted an array of arrays, you could use
...fetch_row (assuming pg_fetch* behaves like mysql_fetch*) or you could keep a counter manually
specifying the index of $myarray.
