I'm having some trouble in creating a AoA
here is the code:
while(($id,$value) = $select->fetchrow_array )
{
push @aoa[$id],$value;
}
as you can see, I get the data from a database, what I'm trying to do is to make a array of arrays where each
@aoa[$id] is a array of values for that $id.
the data is like this:
id value
1 3
1 2
1 10
2 5
2 6
3 4
.. ...
but a got a compile error:
Type of arg 1 to push must be array (not array slice) at file.pl line
+62, near "$aoa;"
what I'm doing wrong here ?
