Parse Error- Unexpected T_String

[system]

I am getting this error and I’m not sure what it means:

Parse error: syntax error, unexpected T_STRING in /home/hecuba7/public_html/dcaa/dcaa/wp-includes/classes.php on line 1602

Here is my code from lines 1600-1606…

[php]function send() {
header(‘Content-Type: text/xml’);
echo “<?xml version='1.0' standalone='yes'?><wp_ajax>”;
foreach ( (array) $this->responses as $response )
echo $response;
echo ‘</wp_ajax>’;
die();[/php]

Please let me know if I need to include any additional info.
Thanks.

I can not see any syntax error in the provided piece of code. Probably somewhere above that code (in the code, not presented here) you missed some closing ?> or " etc.
