I don't really see a need for multidimensional arrays here. A single
associative array would serve perfectly well. For example, the
following is the simplest way to do what you described:

$table = array("A" => "A1", "B" => "B1", "C" => "C1");
$text = strtr($text, $table);

For something requiring more sophisticated handling, you might want to
use preg_replace(), passing twos arrays as parameters.
