note 125917 added to function.explode

When using 'explode' to create an array of strings from a user-specified string that contains newline characters, you may wish the resulting array to correctly reflect the user's intentions by ignoring any final empty line (many users like to end multi-line input with a final newline, for clarity). Here is a function to call after 'explode' to support this effect: // When using explode, delete the last line in the array of lines when it is empty function IgnoreEmptyLastLine(&$linesArr) { $last=count($linesArr)-1; if ($last>=0 && !$linesArr[$last]) unset($linesArr[$last]); } // IgnoreEmptyLastLine ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.245 (proxied: 98.2.238.89) ---- Manual Page -- http://php.net/manual/en/function.explode.php Edit -- https://master.php.net/note/edit/125917 Del: integrated -- https://master.php.net/note/delete/125917/integrated Del: useless -- https://master.php.net/note/delete/125917/useless Del: bad code -- https://master.php.net/note/delete/125917/bad+code Del: spam -- https://master.php.net/note/delete/125917/spam Del: non-english -- https://master.php.net/note/delete/125917/non-english Del: in docs -- https://master.php.net/note/delete/125917/in+docs Del: other reasons-- https://master.php.net/note/delete/125917 Reject -- https://master.php.net/note/reject/125917 Search -- https://master.php.net/manage/user-notes.php
