Can't seem to figure out this php error -

i've been trying figure out php error day. sigh. i'm new coding thought had figured out. when run code, error

parse error: syntax error, unexpected 'body' (t_string), expecting ')' in /users/baronjon/sites/squaredb/functions.php on line 20

and here code:

<?php  function add_post($userid, $body) {     $sql = "insert posts (user_id, body, stamp)                     values ($userid, '". mysql_real_escape_string($body)."', now())";                      $result = mysql_query($sql);  } function show_posts($userid) {     $posts = array();      $sql = "select body, stamp posts         user_id ='$userid' order stamp desc";     $result = mysql_query($sql);      while($data = mysql_fetch_object($result)) {     $posts[] = array(       'stamp' => $data->stamp,                                                 'userid => $userid                                                           'body' => $data->body   //**this line 20.**                              );     }     return $posts;  }  ?> 

being new php (and coding in general) realize simple. don't see parenthesis it's telling me for.

i looked in php manual make sure had syntax correct , seem pretty straightforward.

can point me in right direction.

in $posts array missing trailing ' quote, , comma.

$posts array should like:

$posts[] = array(         'stamp' => $data->stamp,   'userid' => $userid,          'body' => $data->body  //**this line 20.**   ); 

many times in php, when says line 20, should looking @ line 19.

as commenter above mentioned recommend using code editor syntax highlighting vim, emacs, sublime text, notepad++ or similar. saves butt every day :).
