your right === does work, I still feel that the internal auto-conversion
should recognize that the string is to long to be an int and treat both as a
sting. how would you force an if statement to use typecasting ?
ie.
if ( '12.00' == '12' )
will equal as true, but maybe I want it to be compared as a string, therfore
false.
if ( (string)'12.00' == (string)'12' )
doesnt work as I have found and you confirmed. ? you have to use strcmp() ?
it would be real nice to see that built in vs a function.

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

?php
function check($var_1, $var_2)

echo a true br\n;
else
echo a false br\n;
if ( (string)$var_1 == (string)$var_2 )
echo b true br\n;
else
echo b false br\n;
if ( strcmp($var_1, $var_2) == 0 )

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).
