From MySQL to take a content field to print out, but the solution to the error

From MySQL to take a content field to print out, but the error
Plan to take a field from MySQL to try the effect of NL2BR function, but error.
Notation (currently, only one record in the database):

PHP Code

  
   $result = mysql_query ("SELECT * from Product limit"), while ($row = Mysql_fetch_array ($result)) {echo nl2br ($row [' Re_ Mark ']);  This is the right error.

Re_mark field type is: Text

If you change the Re_mark to ID field, it is not an error.

PHP Code

  
   $result = mysql_query ("SELECT * from Product limit"), while ($row = Mysql_fetch_array ($result)) {echo "";//Write Error}

Error content:
Parse error:syntax error, unexpected t_encapsed_and_whitespace, expecting t_string or t_variable or t_num_string in D:\xa Mpp\htdocs\qry.php on line 9

------Solution--------------------
Var_dump ($row [' pic ']); Post the results
------Solution--------------------
discuss

Syntax error? What's wrong?

------Solution--------------------
echo "";//Write Error
This is inevitable, because you violate PHP's writing conventions.

This is all possible:
echo "";
echo "";
