T_CONSTANT_ENCAPSED_STRING Error

[mycro]

Does anyone know why I get this error when I use this script? The point of this script is to hold 5 rows thats inputted frmo a text field called "textfield". Thanks

Parse error: parse error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/..../test/submit.php on line 6

<?php

$a = file('data.txt'); 
if (($c = count($a)) == 5)
   unset($a[0]);
$a[$c] = $textfield "\n";
$f = fopen('data.txt', 'w'); 
foreach ($a as $string) 
   fwrite($f, $string); 
fclose($f);

?>

Changing it from quotes (") to single quotes "'" around \n didn't help it at all. Still getting an error. When I take away the whole \n thing, I don't get an error though.

$a[$c] = $textfield . "\n";
