What is the integer value of the string "foo" ?  When you are using a loosely 
typed language you have to understand that there will be type juggling when you 
try to compare an integer to a string.  If you want a strict comparison, use ===.

Ok entendi que todas as strings quando convertidas para integer recebe o valor 0 "zero", nestas situações realmente deve se utilizar o sinal ===

Obrigado.

Ok I understand that all strings when converted to integer assigned the value 0 "zero" in these situations really should use the sign ===

Thanks.
