[PHP-DB] Re: Subject: diference between == and ===

[Neil Smith [MVP, Digital media]]

The PHP manual (a useful read btw !) states that === tests for equality and 
*exact* equivalence, that is:

If you test for ==='1' then $var must be a string for the result to be true
if you test for ===1 then $var must be an integer or double type for the 
result to be true

Usually its used in tests of $var===0 where you might have a value of Zero 
(numeric) or False (boolean) and its the only way to tell them apart, as 
usually Zero also is equivalent to False in PHP.

Subject: diference between == and ===
Hi guys..

 Wich is the diference between if ($var == '1')  or if ($var === '1')
== means equality and what does the === means ?!
