will suddenly fail. How wonderful! (irony)
Just to make this more fun: Assume $db is PDO then the behavior will
depend on the driver (and for some drivers even at the configuration,
i.e. setting of PDO::ATTR_EMULATE_PREPARES with MySQL) what will happen.
I don't understand exactly what you mean here. This RFC has nothing todo
with DB layer and PDO.
Do you have any example where a DB returns integers differently?
On your example the comparison only fails if the GET-variable is a non
human formed integer means prefixing with a whitespace (but not
suffixing), prefixing with a 0 or formed as a real number or hex.
I'm very sure the changed behavior doesn't open big real life BC issues.
I will run some testsuites on it.
