note 100166 deleted from function.stripos by danbrown

Note Submitter: guanfenglin at gmail dot com ---- Just a friendly hint: I came across to this scenario, check to see if an URL string contains http, if no then prepend "http" to the URL string <?php $url = (stripos($url,"http")==false) ? "http".$url : $url; ?> now, this will always add the http:// to the URL string even the URL string already has http It is because stripos($url,"http") will return false if no http found, and stripos($url, "http") will return 0 if it is found (being at the start of the string) , and (0==false) is a true condition therefore, to fix this problem, we have to use (===) to compare the value type as well: <?php $url = (stripos($url,"http")===false) ? "http".$url : $url; ?> James Lin
