note 51980 added to function.preg-replace

Don't know if this a bug or not, but using a Windows NT localhost 5.0 build 2195 (PHP 4.3.1) I noticed that preg_replace will actually replace a $GLOBALS variable rather than making the replacement just to a new variable, ie: <?php $GLOBALS['mainurl'] = "http://www.website.com/"; //remove last slash $mainurl = preg_replace("|/$|", "", $GLOBALS['mainurl']); ?> results in $GLOBALS['mainurl'] = "http://www.website.com" and $mainurl = "http://www.website.com" I'm under the impression that $GLOBALS variables are distinct from local variables of the same name. Then again, I could be wrong. ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51980 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51980&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51980&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51980&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51980&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51980&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51980&report=yes Search -- http://master.php.net/manage/user-notes.php
