I'm a bit confused...
Are you proposing a new PHP function to check if 2 integers are equal?
The usecase being a callback function for u*sort()?
What happens when it gets passed an string? or an object with a
__toString() ? the string "100$ USD"?
I am a bit skeptical here..
Sure, I have written that code snippet millions of times, but I have
also written that between() snippet million times..
Don't think it deserves to become a PHP core function though.
When I write the function I can atleast control what happens with
non-ints.. like if ($a instanceof ValueObject) { $a->getNumeric() ..
Can't see the point of adding the trillionth "helper" function into PHP.
