While most constants are only defined in one namespace, the case-insensitive true, false, and null
constants are defined in ALL namespaces. So, this is not valid:
<?php namespace false;
const ENT_QUOTES = 'My value';
echo ENT_QUOTES;//Outputs as expected: 'My value'
const FALSE = 'Odd, eh?';//FATAL ERROR! ?>
Fatal error: Cannot redeclare constant 'FALSE' in /Volumes/WebServer/0gb.us/test.php on
