为什么我在这个PHP代码中得到一个解析错误？ [关闭]

Here is my error:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/socia125/public_html/poke.php on line 19

This is line 19 of my code:

$sql="INSERT INTO feed (user_id, feed_text, time) VALUES($user,'You'.mysql_real_escape_string($_POST['kiss_option']).'yourself',UNIX_TIMESTAMP())";

Why am I getting this error?

$sql = "INSERT INTO feed (user_id, feed_text, time)
        VALUES($user, 'You ".mysql_real_escape_string($_POST['kiss_option'])." yourself', UNIX_TIMESTAMP())";
