Change variable within array

Question

My target is to assign a number to the string in the array.

  $lang = array (
    'title'         => "Der Anti-Spam Dienst",
    'button-login'  => "Jetzt $number via Twitter anmelden."
   );

The $number should be set like $lang['button-login'][5] - but I don't have any idea how to access the variable in the array. maybe you can help me.

Thanks!

You should declare the $number variable before the array:

$number = 5;

$lang = array(
    'title'         => "Der Anti-Spam Dienst",
    'button-login'  => "Jetzt $number via Twitter anmelden."
);

Update: If you want to set it afterwards, you'll have to use str_replace:

$lang = array(
    'title'         => 'Der Anti-Spam Dienst',
    'button-login'  => 'Jetzt $number via Twitter anmelden.'
);

echo str_replace('$number', 5, $lang['button-login']);

See it here in action: http://viper-7.com/7QtpF7

Note: the strings should be surrounded by single quotes, so that $number is not parsed as a variable.

@H3rrVorr4g3nd - Not sure I fully understand what you're trying to do. If you want to do it afterwards, see my update.
