And for those changes and breaks on code the user contribution on end of function descriptions would be welcome too. Example from php pg_connect (PHP 4, PHP 5) resource pg_connect ( string $connection_string ) http://br2.php.net/manual/en/function.pg-connect.php 2010/3/29 Worth Lutz <w...@mindspring.com> I don't think that the documentation has caught up with the changes in the program. People using older versions of MapServer have to use the older method and the new method is used for 5.6+ version. It was described briefly in the migration document but took me some experimentation to get results.

But I don't understand why shapeObj getFeature is in the documentation?

But I want to use the script for queryByShape and queryByAttributes too. Why there comes no array in $attr = $shpobj->values; ? Any idea?
