Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

You have not specified the $strict parameter of array_search, so the comparison is done using ==. As 0 == 'green' that is the element that's found. If you want type-strict comparison pass true as the last parameter.
