unexpected T DOUBLE ARROW

[PartisanEntity]

I keep getting the following error with this script:

Parse error: syntax error, unexpected T_DOUBLE_ARROW

Line 22 is where the if statement starts:

$content = mysql_query("SELECT * FROM users where nick = '$username'");

//check to make sure we have this user
$success = mysql_fetch_row($content);

while($row = mysql_fetch_array($content))
{
$db_password = $row['password'];
}

if ($success[0] => 1 && $password == $db_password) {
$_SESSION['loggedin'] = 1;
}
else {header('Location: /login.php?error=1');}

I fixed the error by changing => to >= in the if statement.

But now I get this error:

Cannot modify header information - headers already sent by (output started at /Applications/webserver/bigproject/login_check.php:22) in /Applications/webserver/bigproject/login_check.php on line 26

Are you getting any other errors prior to this error?! Basically, as the error states, you cannot send http headers once you have started to output your page (inc. any errors that are output/sent to the browser), in which case the headers have already been sent (to the client).

Any blank lines / spaces before your opening <?php ...?

$success = mysql_fetch_row($content);

What are you trying to do with that line?
