This is not a bug, but expected behaviour. The last iteration of the 
foreach with reference value references itself, with a current value of 
'one3' at that point, thus saving one3 as last value.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

As explained by Felix.
