note 81086 added to function.substr-replace

There is a mistake in the mb_substr_replace function below, when the $length parameter is given negative. Here is a working version. <?php //Check to see if it exists in case PHP has this function later if (!function_exists("mb_substr_replace")){ //Same parameters as substr_replace with the extra encoding parameter. function mb_substr_replace($string, $replacement, $start, $length=null, $encoding=null) { if ($encoding == null) $encoding = mb_internal_encoding(); if ($length == null) { return mb_substr($string, 0, $start, $encoding) . $replacement; } else { if($length < 0) $length = mb_strlen($string, $encoding) - $start + $length; return mb_substr($string, 0, $start, $encoding) . $replacement . mb_substr($string, $start + $length, mb_strlen($string, $encoding), $encoding); } } } ?> ---- Server IP: 87.124.64.96 Probable Submitter: 84.14.214.74 ---- Manual Page -- http://www.php.net/manual/en/function.substr-replace.php Edit -- https://master.php.net/note/edit/81086 Del: integrated -- https://master.php.net/note/delete/81086/integrated Del: useless -- https://master.php.net/note/delete/81086/useless Del: bad code -- https://master.php.net/note/delete/81086/bad+code Del: spam -- https://master.php.net/note/delete/81086/spam Del: non-english -- https://master.php.net/note/delete/81086/non-english Del: in docs -- https://master.php.net/note/delete/81086/in+docs Del: other reasons-- https://master.php.net/note/delete/81086 Reject -- https://master.php.net/note/reject/81086 Search -- https://master.php.net/manage/user-notes.php
