Bug description:Loose comparison too loose
Description:
------------
if ("0080" == "80e0") echo "Smoking crack!";
I created a double octet coded character set. I'm using 4 hex to represent
each character. I'm using a switch statement to get a token based on the
value. The string "80e0" is incorrectly setting off the case "0080"
statement.
The strict comparison of === works as expected, but the switch uses a loose
comparison.
Test script:
---------------
if ("0080" == "80e0") {
echo "Too loose";
} else {
echo "Just right";
}
Expected result:
----------------
Just right
Actual result:
--------------
Too loose
