Answer 1

Converting to a boolean causes all values to be evaluated to true except:
* 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
* the special type NULL (including unset variables)
* SimpleXML objects created from empty tags

Try writing
$x = '0', and the result will be false.

Also notice something random like:
$x = 'The sun is warm101', will result in true.

Answer 2

When you write 'false' or 'true' those are strings not the boolean values true and false. And in PHP I believe non-empty strings are evaluated to be the boolean value true. That is why you were getting those results.
