note 100166 added to function.stripos

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 $url = (stripos($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: $url = (stripos($url,"http")===false) ? "http".$url : $url; James Lin ---- Server IP: 69.147.83.197 Probable Submitter: 210.55.214.5 ---- Manual Page -- http://www.php.net/manual/en/function.stripos.php Edit -- https://master.php.net/note/edit/100166 Del: integrated -- https://master.php.net/note/delete/100166/integrated Del: useless -- https://master.php.net/note/delete/100166/useless Del: bad code -- https://master.php.net/note/delete/100166/bad+code Del: spam -- https://master.php.net/note/delete/100166/spam Del: non-english -- https://master.php.net/note/delete/100166/non-english Del: in docs -- https://master.php.net/note/delete/100166/in+docs Del: other reasons-- https://master.php.net/note/delete/100166 Reject -- https://master.php.net/note/reject/100166 Search -- https://master.php.net/manage/user-notes.php
