There isn't an option for indenting depth so it's always two spaces. If you want more than this you can use a simple regex.

Converting from two spaces to four:
<?php
$yaml 
preg_replace('/^(  +)/m''$1$1'$yaml);
?>

Add two more $1 into the replacement for eight spaces.

Note that NULL values will be converted to the tilde character "~".

This can be somehow counter-intuitive, but that is absolutely legit, and it seems it is a standard recognized by every Yaml parser. So, don't worry about that. Yaml reference:
