Will comparison of string "25" and integer 52 work in PHP?

well it seems to me that at least a warning should be given when comparing an integer 0 to a non-integer value that evaluates to 0 when cast as an int unless an explicit type cast is used without using strict equals.
i can see why this behaviour is not a bug, because (int)'SOME STRING' == 0, but it's also has the potential to cause unexpected results/bugs unless you use strict equals everywhere.
in this case, i fixed the problem by using === instead of ==, but it took a bit of time to track down the error because there was no warning or anything. i think that it would be better to require someone to do:
if($value == (int)'SOME STRING')
OR
if($value === 'SOME STRING')
in order to avoid a warning being emmited if $value == 0.
