+  * something strange in PHP. It seems that global arrays defined in an INCLUDED files are local to the included file and their range disappears in the including file:
+<code php>
+<?php
+// foo.php
+$ar = array('alice', 'bob') ;
+function baz()
+  {
+  global $ar ;
+  echo is_array($ar) ? 'True' : 'False' ;

+?>

+<code php>
+<?php
+// qux.php
+require 'foo.php';
+baz();
+?>

+  * qux.php displays True as expected.
+  * bar.php displays False (???)
+  * bug, feature, or test error ?
+  * Tested with PHP 5.0.4
