note 72643 added to function.preg-replace

OK, so I figured out how to remove the url at the beginning and end easier, but then found I needed additional checks due to slight changes in the way the urchin tags were written at times. :( So, I brought it down to this: <?php $siterefname = $_SERVER['HTTP_REFERER']; // remove everything to the left of the urchin code "utmcsr%3D" and a few other possibilities (or everything to the left of it) $siterefname = preg_replace('/(.*)(.*?)utmcsr%3D/i', '', $siterefname); $siterefname = preg_replace('/(.*)(.*?)utmcsr=/i', '', $siterefname); $siterefname = preg_replace('/(.*)(.*?)utm_source%3D/i', '', $siterefname); $siterefname = preg_replace('/(.*)(.*?)utm_source=/i', '', $siterefname); //remove the code after the desired urchin text (or everything to the right of "%7Cutmccn") and a few other possibilities $siterefname = preg_replace('/%7Cutmccn(.*?)(.*)/i', '', $siterefname); $siterefname = preg_replace('/|Cutmccn(.*?)(.*)/i', '', $siterefname); $siterefname = preg_replace('/&utm_medium=(.*?)(.*)/i', '', $siterefname); $siterefname = preg_replace('/&__utmv(.*?)(.*)/i', '', $siterefname); //remove the extra characters and replace them with cleaner looking chars (in this case the plus char "+") $siterefname = str_replace("%7C","+",$siterefname); $siterefname = str_replace("%3D","+",$siterefname); $siterefname = str_replace("%2B","+",$siterefname); ?> I was told that this value "(.*?)" is either, not necessary or the "?" mark is not, and that I can get this down to a single line, although I'm not sure how to get it down to one line yet. Any suggestions. :) ---- Server IP: 216.194.113.175 Probable Submitter: 24.17.235.127 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- https://master.php.net/note/edit/72643 Del: integrated -- https://master.php.net/note/delete/72643/integrated Del: useless -- https://master.php.net/note/delete/72643/useless Del: bad code -- https://master.php.net/note/delete/72643/bad+code Del: spam -- https://master.php.net/note/delete/72643/spam Del: non-english -- https://master.php.net/note/delete/72643/non-english Del: in docs -- https://master.php.net/note/delete/72643/in+docs Del: other reasons-- https://master.php.net/note/delete/72643 Reject -- https://master.php.net/note/reject/72643 Search -- https://master.php.net/manage/user-notes.php
