note 97777 added to ref.math

On avg_vals function i made a minor mistake I was editing some code and made up two functions which may come in handy, they are to work out the average value of multiple values. Working with array: <?php } elseif ( (is_string($avg_vals) && strlen <= 2) && (is_string($avg_delimiter) && !empty($avg_delimiter)) ) { ?> Needs to be: <?php } elseif ( (is_string($avg_vals) && strlen($avg_vals) <= 2) && (is_string($avg_delimiter) && !empty($avg_delimiter)) ) { ?> ---- Server IP: 78.110.173.36 Probable Submitter: 82.1.142.218 ---- Manual Page -- http://www.php.net/manual/en/ref.math.php Edit -- https://master.php.net/note/edit/97777 Del: integrated -- https://master.php.net/note/delete/97777/integrated Del: useless -- https://master.php.net/note/delete/97777/useless Del: bad code -- https://master.php.net/note/delete/97777/bad+code Del: spam -- https://master.php.net/note/delete/97777/spam Del: non-english -- https://master.php.net/note/delete/97777/non-english Del: in docs -- https://master.php.net/note/delete/97777/in+docs Del: other reasons-- https://master.php.net/note/delete/97777 Reject -- https://master.php.net/note/reject/97777 Search -- https://master.php.net/manage/user-notes.php
