use ===

'word' is converted to an integer for the comparison, and thus 0 == 0.

try this code:

if(array('word')===array(0)) echo "ERROR";

Thanks for explanations.

Comparison === needed ONLY if, during type conversion, we got same values, so String compare to Integer should be compared using Integer converted to string and check if they are equal. 

So if String is '' and Int is 0
or '1' == 1
'2' == 2
.. etc. only in this cases === is necessary to tell VARIABLE TYPE difference.

It's so obvious, why I'm explaining all this to you ?! You should know this better than me! Please fix this BUG

@radamanf: He is comparing with == so all array elements are also compared with ==. And as in PHP 'word'==0 they are considered equal. Are you suggesting that when you compare arrays with == the elements should be compared with ===? That makes no sense to me.
