note 111270 added to function.strtr

Since strtr (like PHP's other string functions) treats strings as a sequence of bytes, and since UTF-8 and other multibyte encodings use - by definition - more than one byte for at least some characters, the three-string form is likely to have problems. Use the associative array form to specify the mapping. <?php // Assuming UTF-8 $str = 'Äbc Äbc'; // strtr() sees this as nine bytes (including two for each Ä) echo strtr($str, 'Ä', 'a'); // The second argument is equivalent to the string "\xc3\x84" so "\xc3" gets replaced by "a" and the "\x84" is ignored echo strtr($str, array('Ä' => 'a')); // Works much better ?> ---- Server IP: 69.147.83.199 Probable Submitter: 122.57.198.170 ---- Manual Page -- http://php.net/manual/en/function.strtr.php Edit -- https://master.php.net/note/edit/111270 Del: integrated -- https://master.php.net/note/delete/111270/integrated Del: useless -- https://master.php.net/note/delete/111270/useless Del: bad code -- https://master.php.net/note/delete/111270/bad+code Del: spam -- https://master.php.net/note/delete/111270/spam Del: non-english -- https://master.php.net/note/delete/111270/non-english Del: in docs -- https://master.php.net/note/delete/111270/in+docs Del: other reasons-- https://master.php.net/note/delete/111270 Reject -- https://master.php.net/note/reject/111270 Search -- https://master.php.net/manage/user-notes.php
