Automatic addition of trailing slash to urlencoded urls

[deLL]

I am very confused about the following:\[code\]echo("<a href='http://".urlencode("www.test.com/test.php?x=1&y=2")."'>test</a><br>");echo("<a href='http://"."www.test.com/test.php?x=1&y=2"."'>test</a>");\[/code\]The first link gets a trailing slash added (that's causing me problems)The second link does not.Can anyone help me to understand why.Clearly it appears to be something to do with urlencode, but I can't find out what.Thanksc
