note 49759 added to ref.strings

if the variable $memberid contains a zero, and you use: if($memberid != '') .... the outcome is false because somehow '0' becomes '' (empty) somehow i found a solution for this: if("$memberid"!='') .... the above expression will distinguish between 0 (zero) and '' (empty string) it cost me 1 nightly hour so i hope it helps someone else ---- Manual Page -- http://www.php.net/manual/en/ref.strings.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49759 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49759&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49759&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49759&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49759&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49759&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49759&report=yes Search -- http://master.php.net/manage/user-notes.php
