note 113216 added to function.fwrite

hi I have used a code of this forum to try a temp setup on my new site to fopen fwrite fclose from a form to a text file as follows: <?php $fp = fopen('top100stats.txt', 'a'); fwrite($fp, '$player_name'); fwrite($fp, '$points'); fclose($fp); // the content of 'data.txt' is now 123 and not 23! ?> however when I submit my form with the variables $player_name $points instead of adding the values from those variables it simply adds the coding to the text file like $player_name$points why is this happening please ---- Server IP: 69.147.83.199 Probable Submitter: 78.150.153.58 ---- Manual Page -- http://php.net/manual/en/function.fwrite.php Edit -- https://master.php.net/note/edit/113216 Del: integrated -- https://master.php.net/note/delete/113216/integrated Del: useless -- https://master.php.net/note/delete/113216/useless Del: bad code -- https://master.php.net/note/delete/113216/bad+code Del: spam -- https://master.php.net/note/delete/113216/spam Del: non-english -- https://master.php.net/note/delete/113216/non-english Del: in docs -- https://master.php.net/note/delete/113216/in+docs Del: other reasons-- https://master.php.net/note/delete/113216 Reject -- https://master.php.net/note/reject/113216 Search -- https://master.php.net/manage/user-notes.php
