Using usort on a php object not working

cmpPriceDesc() should follow usort's specs:

The comparison function must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

It'd be as simple as:

function cmpPriceDesc($a, $b)   {
    return $b->product_price -

I'm inferring you want higher values first given the Desc in the function name.

Datarow object, why is this code working?
Both DataTable and DataRow are reference data types. This means that when you assign a variable to its reference in code, it simply holds a pointer back to the same memory location. DataRow dr1 = mydataset.Tables["NewTable"].Rows[0]; DataRow dr2 = mydataset.Tables["NewTable"].Rows[0]; DataRow dr3 = dr1; DataTable dt = mydataset.Tables["NewTable"]; DataRow dr4 = dt.Rows[0]; In the above example,
