note 72091 added to function.chr

This is just a small piece that allows you to echo out a set number of characters from a string. We were writing option values (html form element) dynamically from an xml file. Some of the strings were too long and as the select tag has no attributes to control the width or columns it seems a handy way to solve the problem. $string = "this is some text"; $length = strlen($string); // gets the length of the string $newLength = -($length - 5); // makes the length smaller by 5 characters $string = substr("$string", 0, $newLength); // sets the string to be 5 characters in length echo $string; ---- Server IP: 212.108.64.74 Probable Submitter: 136.206.1.17 (proxied: 136.206.229.110) ---- Manual Page -- http://www.php.net/manual/en/function.chr.php Edit -- https://master.php.net/note/edit/72091 Del: integrated -- https://master.php.net/note/delete/72091/integrated Del: useless -- https://master.php.net/note/delete/72091/useless Del: bad code -- https://master.php.net/note/delete/72091/bad+code Del: spam -- https://master.php.net/note/delete/72091/spam Del: non-english -- https://master.php.net/note/delete/72091/non-english Del: in docs -- https://master.php.net/note/delete/72091/in+docs Del: other reasons-- https://master.php.net/note/delete/72091 Reject -- https://master.php.net/note/reject/72091 Search -- https://master.php.net/manage/user-notes.php
