note 125015 added to intlchar.tolower

The other function I wrote to replace mb_strtolower may not work properly, as it erroneously equated graphemes with codepoints. tolower, like many IntlChar methods, works specifically on codepoints, so requires a codepoint iterator to isolate each. Also, because in tolower, if there is no lowercase version of the codepoint, the supplied one is returned, so there is no need to specially test for alphabetic codepoints before conversion. <?php function u_tolower($text=''){ // if blank, return blank (don't waste CPU cycles) if($text==''){return'';} // create the codepoint break iterator to identify the start of each codepoint $iterator=IntlBreakIterator::createCodePointInstance(); // load the text $iterator->setText($text); // using a parts iterator to extract each codepoint itself, convert and append it to the new string $newtext=''; foreach($iterator->getPartsIterator() as $codepoint){$newtext.=IntlChar::tolower($codepoint);} // return converted text return $newtext; } ?> ---- Server IP: 45.112.84.4 Probable Submitter: 101.0.109.162 (proxied: 61.68.126.217) ---- Manual Page -- http://php.net/manual/en/intlchar.tolower.php Edit -- https://master.php.net/note/edit/125015 Del: integrated -- https://master.php.net/note/delete/125015/integrated Del: useless -- https://master.php.net/note/delete/125015/useless Del: bad code -- https://master.php.net/note/delete/125015/bad+code Del: spam -- https://master.php.net/note/delete/125015/spam Del: non-english -- https://master.php.net/note/delete/125015/non-english Del: in docs -- https://master.php.net/note/delete/125015/in+docs Del: other reasons-- https://master.php.net/note/delete/125015 Reject -- https://master.php.net/note/reject/125015 Search -- https://master.php.net/manage/user-notes.php
