I know there is a lot of documentation around this but this one line of code took me ages to find in a 4000 line file, and I would like to get it right the first try.

file_put_contents($myFile,serialize(array($email_number,$email_address))) or die("can't open file");
    if ($address != "[email protected]") {
        $email['headers'] = array('CC' => '[email protected]');
    }
}

After this if statement I basically want to add on

'BCC' => '[email protected]'

into the $email['headers'] array (so it adds it whether the if evaluates to true or not)

You can add them individually like this:

$array["key"] = "value";

Collectively, like this:

$array = array(
    "key"  => "value",
    "key2" => "value2"
);

Or you could merge two or more arrays with array_merge:

$array = array( "Foo" => "Bar", "Fiz" => "Buz" );

$new = array_merge( $array, array( "Stack" => "Overflow" ) );

print_r( $new );

Which results in the news key/value pairs being added in with the old:

Array
(
  [Foo] => Bar
  [Fiz] => Buz
  [Stack] => Overflow
)
