that's what === is for (real comparisons without casting).

The conversion to a number is necessary because programmers don't differentiate
between strings and numbers in PHP. Consider the following code:
if ($_GET["a"] == $_GET["b"]) echo "a is same as b!";
The result will be the same if the query string is ?a=1&b=1 or ?a=1&b=1.0 or ?
a=01&b=1 because PHP is loosely typed.
Internally $_GET["a"] and $_GET["b"] are both strings, but we can't do a string
comparison. If you want a string comparison, use strcmp.

I'm confused as to why there is even a conversation around "should we fix this".
The data objects are strings. Sure, PHP is "loosely typed" but shouldn't it do
the comparison you tell it to do first before attempting anything else?
I agree with the previous suggestion: make it a real string comparison and drop
the type casting.
