You are looking for the position of a specific characther, so use the search
facility on php.net by entering "position" and selecting "all php.net sites"
or "this mirror only" from the select next to the input box. The first
search result is the one you are looking for.

When the error is a notice, the probable cause would be that you didn't
initialize $myName.
If you want to learn PHP (or any other new language for that matter), the
best way is to start from scratch; point your browser to
http://www.php.net/manual/en/getting-started.php to start with the basics.
