Fix in strip_tags

Hello again, In strip_tags there is a note that says: --- This parameter should not contain whitespace. strip_tags sees a tag as a case-insensitive string between /</ and the first whitespace or />/. It means that /strip_tags("<br/>", "<br>")/ returns an empty string. --- The given code, obviously, will not return an empty string. Probably someone forgot to add an example whitespace to the code. I updated the second parameter in the example from <br> to <br >. Cheers, Adam
