(string) casting won't help as it takes place *before* autoconversion
just use strcmp() or the tripple === operator

ok I can understand the first if() failing, php is conffused and things I want to
compare int not strings, this is a peave because php only supports upto signed long
int, which this is much larger, I think php should realize this and compare them as
strings.
the second fails too .. ? this is strange because I have spec. type casted that as
strings, they should compare fine as strings. this is where I beleive there is more
then a quirk and more of a bug.
the third susceeds just as it should, its just not near as elegant as a simple if
($var_1 == $var_2).
