note 63831 added to reserved.variables

I was unable to convince my hosting company to change their installation of PHP and therefore had to find my own way to computer $_SERVER["DOCUMENT_ROOT"]. I eventually settled on the following, which is a combination of earlier notes (with some typos corrected): <?php if ( ! isset($_SERVER['DOCUMENT_ROOT'] ) ) $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr( $_SERVER['SCRIPT_FILENAME'], 0, 0-strlen($_SERVER['PHP_SELF']) ) ); ?> ---- Server IP: 64.71.164.2 Probable Submitter: 24.3.105.17 ---- 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/reserved.variables.php Edit -- http://master.php.net/note/edit/63831 Del: integrated -- http://master.php.net/note/delete/63831/integrated Del: useless -- http://master.php.net/note/delete/63831/useless Del: bad code -- http://master.php.net/note/delete/63831/bad+code Del: spam -- http://master.php.net/note/delete/63831/spam Del: non-english -- http://master.php.net/note/delete/63831/non-english Del: in docs -- http://master.php.net/note/delete/63831/in+docs Del: other reasons-- http://master.php.net/note/delete/63831 Reject -- http://master.php.net/note/reject/63831 Search -- http://master.php.net/manage/user-notes.php
