Edit report at http://bugs.php.net/bug.php?id=52579&edit=1 ID: 52579 Updated by: johannes@php.net Reported by: johnston dot joshua at gmail dot com Summary: define() accepts characters out of range -Status: Open +Status: Bogus Type: Bug Package: Scripting Engine problem Operating System: Any PHP Version: 5.3.3 Block user comment: N New Comment: 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 A constant may contain any character. Use constant() to retrieve the value. Only the parser doesn't allow any name but that's independent.

The documentation is correct but there seems to be no validation that matches the docs when the constant's name is assigned to zend_constant.name According to the docs on Constants: The name of a constant follows the same rules as any label in PHP. A valid constant name starts with a letter or underscore, followed by any number of letters, numbers, or underscores. As a regular expression, it would be expressed thusly: [a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]* Test script: --------------- <?php define('/', 'slash'); echo constant('/'); // works echo /; // parse error as expected ?> Expected result: ---------------- define() should throw an error stating that the constant name has invalid characters in it ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52579&edit=1
