note 49970 added to ref.simplexml

I'm new to PHP and XML, but I think others might pull their hair out over this too. I forgot about XML and whitespace when I was populating an array with node values, and was getting what appeared to be duplicate values despite using array_unique(). Use trim() when populating an array or assigning a variable. <?php $xml_array = array(); foreach ($resource->xpath($node_match) as $option){ $xml_array[$i] = trim($option); $i++; } $xml_unique_array = array_unique($xml_array); ?> ---- Manual Page -- http://www.php.net/manual/en/ref.simplexml.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49970 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49970&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49970&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49970&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49970&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49970&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49970&report=yes Search -- http://master.php.net/manage/user-notes.php
