note 77519 added to function.set-include-path

You cannot eliminate the path using '' (lambda, 0-length string). In other words, this doesn't do what you think it does (in PHP 4 or 5): <?php set_include_path(''); // does NOT set PATH to '' ini_set('include_path', ''); // also does NOT set PATH to '' ?> The only "work-around" I've found is to use a whitespace string: <?php set_include_path(' '); // sets PATH to ' ' ini_set('include_path', ' '); // also sets PATH to ' ' ?> This is arguably a bug, as there are situations where security demands you eliminate the include path and explicitly state the path for all included files. http://bytejar.com/ - Software Lessons Learned the Hard Way ---- Server IP: 69.147.83.197 Probable Submitter: 24.148.133.105 ---- Manual Page -- http://www.php.net/manual/en/function.set-include-path.php Edit -- https://master.php.net/note/edit/77519 Del: integrated -- https://master.php.net/note/delete/77519/integrated Del: useless -- https://master.php.net/note/delete/77519/useless Del: bad code -- https://master.php.net/note/delete/77519/bad+code Del: spam -- https://master.php.net/note/delete/77519/spam Del: non-english -- https://master.php.net/note/delete/77519/non-english Del: in docs -- https://master.php.net/note/delete/77519/in+docs Del: other reasons-- https://master.php.net/note/delete/77519 Reject -- https://master.php.net/note/reject/77519 Search -- https://master.php.net/manage/user-notes.php
