[PHP] Parse error: syntax error, unexpected '_' (T_STRING)

Hello,

I get the the error, could you help me? Thanks.

"Parse error: syntax error, unexpected '_' (T_STRING), expecting ']' in C:\xampp\htdocs\processfeedback.php on line 30"

Line 30 refers to the very first line of the code I have posted below
=================

if (!eregi('^[a-zA-Z0-9_\-\.]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$', $email)) {
echo "<p>That is not a valid email address.</p>".
<p>Please return to the previous page and try again.</p>";
exit;
}
$toaddress = "feedback@example.com"; // the default value
if (eregi("shop|customer service|retail", $feedback))
$toaddress = "retail@example.com";
} else if (eregi("deliver|fulfill", $feedback)) {
$toaddress = "fulfillment@example.com";
} else if (eregi("bill|account", $feedback)) {
$toaddress = "accounts@example.com";
}
if (eregi("bigcustomer\.com", $email)) {
$toaddress = "bob@example.com";
}
?>
