Note Submitter: Alex ---- I think everybody should read carefully what "jeronimo at DELETE_THIS dot transartmedia dot com" wrote. It's a great pitfall even for seasoned programmers and should be looked upon with a great attention. For example, comparing passwords with == may result in a very large security hole. I would add some more to it: The workaround is to use strcmp() or ===. Note on ===: While the php documentation says that, basically, ($a===$b) is the same as ($a==$b && gettype($a) == gettype($b)), this is not true. The difference between == and === is that === never does any type conversion. So, while, according to documentation, ("+0.1" === ".1") should return true (because both are strings and == returns true), === actually returns false (which is good).
