Re: [PHP] why true?

2002-08-11 Thread Rasmus Lerdorf 

Because you are comparing a string to a number.  PHP has to choose to
either compare the two as strings or as numbers.  The numerical value of
the string 'test' is 0 which means it works out to 0 == 0 which is true.

If you want to force a string comparison, you can use strcmp() or, if you
want to force a comparison on both value and type, use === instead of ==

Try 

echo ('test'=='0');

and you'll see what Rasmus meant.
