note 124158 added to function.preg-split

Assuming you're using UTF-8, this function can be used to separate Unicode text into individual codepoints without the need for the multibyte extension. <?php preg_split('//u', $text, -1, PREG_SPLIT_NO_EMPTY); ?> The words "English", "Español", and "Русский" are all seven letters long. But strlen would report string lengths 7, 8 and 14, respectively. The preg_split above would return a seven-element array in all three cases. It splits '한국어' into the array ['한', '국', '어'] instead of the 9-character array that str_split($text) would produce. ---- Server IP: 208.43.231.9 Probable Submitter: 101.0.109.162 (proxied: 122.58.132.37) ---- Manual Page -- http://php.net/manual/en/function.preg-split.php Edit -- https://master.php.net/note/edit/124158 Del: integrated -- https://master.php.net/note/delete/124158/integrated Del: useless -- https://master.php.net/note/delete/124158/useless Del: bad code -- https://master.php.net/note/delete/124158/bad+code Del: spam -- https://master.php.net/note/delete/124158/spam Del: non-english -- https://master.php.net/note/delete/124158/non-english Del: in docs -- https://master.php.net/note/delete/124158/in+docs Del: other reasons-- https://master.php.net/note/delete/124158 Reject -- https://master.php.net/note/reject/124158 Search -- https://master.php.net/manage/user-notes.php
