A boolean TRUE value is converted to the string "1". Boolean FALSE is converted to "" (the empty string). This allows conversion back and forth between boolean and string values.

We converting the in boolean datatype in FALSE:

the boolean FALSE itself the integer 0 (zero)
the special type NULL (including unset variables)
an object with zero member variables (PHP 4 only) string "0"
SimpleXML objects created from empty tags
the empty string,and the
the float 0.0 (zero)
an array with zero elements

Every other value is considered TRUE.
