in reply to Disadvantage of using 'eq' operator to compare numbers.

Strings can look like 0 to the == operator and you can get into uncalled for hithces if you swap the string and numeric operators:
$apples = "apples"; $oranges = "oranges"; if($apples == $oranges){ print "$apples and $oranges are the same"; }else { print "$apples and $oranges are not the same"; }



Excellence is an Endeavor of Persistence. Chance Favors a Prepared Mind.
