note 118326 added to function.preg-split

This regular expression will split a long string of words into an array of sub-strings, of some maximum length, but only on word-boundries. I use the reg-ex with preg_match_all(); but, I'm posting this example here (on the page for preg_split()) because that's where I looked when I wanted to find a way to do this. Hope it saves someone some time. <?php // example of a long string of words $long_string = 'Your IP Address will be logged with the submitted note and made public on the PHP manual user notes mailing list. The IP address is logged as part of the notes moderation process, and won\'t be shown within the PHP manual itself.'; // "word-wrap" at, for example, 60 characters or less $max_len = 60; // this regular expression will split $long_string on any sub-string of // 1-or-more non-word characters (spaces or punctuation) if(preg_match_all("/.{1,{$max_len}}(?=\W+)/", $long_string, $lines) !== False) { // $lines now contains an array of sub-strings, each will be approx. // $max_len characters - depending on where the last word ended and // the number of 'non-word' characters found after the last word for ($i=0; $i < count($lines[0]); $i++) { echo "[$i] {$lines[0][$i]}\n"; } } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 172.97.96.90 ---- Manual Page -- http://php.net/manual/en/function.preg-split.php Edit -- https://master.php.net/note/edit/118326 Del: integrated -- https://master.php.net/note/delete/118326/integrated Del: useless -- https://master.php.net/note/delete/118326/useless Del: bad code -- https://master.php.net/note/delete/118326/bad+code Del: spam -- https://master.php.net/note/delete/118326/spam Del: non-english -- https://master.php.net/note/delete/118326/non-english Del: in docs -- https://master.php.net/note/delete/118326/in+docs Del: other reasons-- https://master.php.net/note/delete/118326 Reject -- https://master.php.net/note/reject/118326 Search -- https://master.php.net/manage/user-notes.php
