Well, it shouldn't, so I'm beginning to suspect that your $foo doesn't contain what you think it does. According to the PHP manual, 'the following values are considered FALSE: the boolean FALSE itself; the integer 0 (zero); the float 0.0 (zero); the empty string, and the string "0"; an array with zero elements; an object with zero member variables; the special type NULL (including unset variables)'. As "\n" is none of those, it should be ==TRUE (but, of course, !==TRUE). Cheers!
