note 110524 added to function.strtr

Since strtr() is twice faster than strlwr I decided to write my own lowering function which also handles UTF-8 characters. <?php function strlwr($string, $utf = 1) { $latin_letters = array('Ă' => 'a', 'Â' => 'a', 'Î' => 'i', 'Ș' => 's', 'Ş' => 's', 'Ț' => 't', 'Ţ' => 't'); $utf_letters = array('Ă' => 'ă', 'Â' => 'â', 'Î' => 'î', 'Ș' => 'ș', 'Ş' => 'ş', 'Ț' => 'ț', 'Ţ' => 'ţ'); $letters = array('A' => 'a', 'B' => 'b', 'C' => 'c', 'D' => 'd', 'E' => 'e', 'F' => 'f', 'G' => 'g', 'H' => 'h', 'I' => 'i', 'J' => 'j', 'K' => 'k', 'L' => 'l', 'M' => 'm', 'N' => 'n', 'O' => 'o', 'P' => 'p', 'Q' => 'q', 'R' => 'r', 'S' => 's', 'T' => 't', 'U' => 'u', 'V' => 'v', 'W' => 'w', 'X' => 'x', 'Y' => 'y', 'Z' => 'z'); return ($utf == 1) ? strtr($string, array_merge($utf_letters, $letters)) : strtr($string, array_merge($latin_letters, $letters)); } ?> This allows you to lower every character (even UTF-8 ones) if you don't set the second parameter, or just lower the UTF-8 ones into their specific latin characters (used when making friendly-urls for example). I used romanian characters but, of course, you can add your own local characters. Feel free to use/modify this function as you wish. Hope it helps. ---- Server IP: 69.147.83.199 Probable Submitter: 86.122.225.45 ---- Manual Page -- http://www.php.net/manual/en/function.strtr.php Edit -- https://master.php.net/note/edit/110524 Del: integrated -- https://master.php.net/note/delete/110524/integrated Del: useless -- https://master.php.net/note/delete/110524/useless Del: bad code -- https://master.php.net/note/delete/110524/bad+code Del: spam -- https://master.php.net/note/delete/110524/spam Del: non-english -- https://master.php.net/note/delete/110524/non-english Del: in docs -- https://master.php.net/note/delete/110524/in+docs Del: other reasons-- https://master.php.net/note/delete/110524 Reject -- https://master.php.net/note/reject/110524 Search -- https://master.php.net/manage/user-notes.php
