It is not wrong to write in a file named foobar.php. <?php $foo = array(foo => "foo", bar =>"bar"); echo $foo[foo]."<br>\n"; ?> If you start that program in PHP 4.2., you get the warnings. Notice: Use of undefined constant foo, assumed 'foo' in foobar.php at line 2 Notice: Use of undefined constant bar, assumed 'bar' in foobar.php at line 2 Notice: Use of undefined constant foo, assumed 'foo' in foobar.php at line 3 foo If the entries of an associative array are strings, then you SHOULD quote them.
