How do i push a new key value pair to an array php?

arrays, drupal, drupal-7, drupal-modules, php

Solution

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
)

Problem

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@domain.com") { $email['headers'] = array('CC' => 'email@domain.com'); } } ``` After this if statement I basically want to add on `'BCC' => 'another_email@domain.com'` into the `$email['headers']` array (so it adds it whether the if evaluates to true or not)
