note 66291 added to function.defined

Beware that some PHP versions return an integer (1 or 0) instead of a boolean. Confirmed PHP versions that return an integer are 4.3.2 and 4.3.4. Relevant bug report: http://bugs.php.net/bug.php?id=27443 This make it impossible to use the following, when the PHP version is not known: if (defined('CONSTANT') === true) { } Relevant commit for PHP 4.3.5 (thanks to Pollita at #php.thinktank): http://cvs.php.net/viewcvs.cgi/Zend/zend_builtin_functions.c? r1=1.124.2.13&r2=1.124.2.14 ---- Server IP: 66.163.161.117 Probable Submitter: 84.166.46.180 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.defined.php Edit -- http://master.php.net/note/edit/66291 Del: integrated -- http://master.php.net/note/delete/66291/integrated Del: useless -- http://master.php.net/note/delete/66291/useless Del: bad code -- http://master.php.net/note/delete/66291/bad+code Del: spam -- http://master.php.net/note/delete/66291/spam Del: non-english -- http://master.php.net/note/delete/66291/non-english Del: in docs -- http://master.php.net/note/delete/66291/in+docs Del: other reasons-- http://master.php.net/note/delete/66291 Reject -- http://master.php.net/note/reject/66291 Search -- http://master.php.net/manage/user-notes.php
