Why does 0 == 'hello' in PHP?

Does PHP use types when doing comparisons?

Sure it should.  PHP is a loosely typed language.  This is how loosely
typed languages work.  You need to be able to compare 1 to "1" for
example.  The integer equivalent of "hello" is 0 and thus 0 ==
"hello".  If you want a string comparison, force both args to be strings
or use strcmp().

In PHP 4 there is a new operator === which does a strict compare.
