While PHP has a lot of nice features, it also has some traps which I am forever 
into. One which I find particularly hard to understand is how mixed mode 
comparisons work.
For instance 

$string =  'elephant';
If($string == 0) returns true;
If($string != 0) returns false;
If($string === 0) returns false; 

I know that in this case I should use 'If($string == '')', but I still manage 
to forget.
Can anyone explain clearly why comparing a string with zero gives this 
anomalous result?
