note 68735 added to function.strtolower

I changed it a bit and i found that it's better to put everything in lowercase, and rebuild the text the same way a teacher corrects a text, for now it only checks that the first letter after a point "." must be in upper case. function RemoveShouting($string) { $string = strtolower(trim($string)); for($i=0;$i<strlen($string);$i++){ if($i==0){$string[$i] = strtoupper($string[$i]);} if($string[$i] == "."){ while($string[$i+1] == " "){ $i++; } $string[$i+1] = strtoupper($string[$i+1]); $i++; } } return $string; } this function would change: Hi mi name is PETER. SOME TIMES I FORGOT TO DISABLE CAPS LOCK. into: Hi mi name is peter. Some times i forgot to disable caps lock. ---- Server IP: 130.206.1.5 Probable Submitter: 213.60.190.240 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.strtolower.php Edit -- https://master.php.net/note/edit/68735 Del: integrated -- https://master.php.net/note/delete/68735/integrated Del: useless -- https://master.php.net/note/delete/68735/useless Del: bad code -- https://master.php.net/note/delete/68735/bad+code Del: spam -- https://master.php.net/note/delete/68735/spam Del: non-english -- https://master.php.net/note/delete/68735/non-english Del: in docs -- https://master.php.net/note/delete/68735/in+docs Del: other reasons-- https://master.php.net/note/delete/68735 Reject -- https://master.php.net/note/reject/68735 Search -- https://master.php.net/manage/user-notes.php
