Variable variables take the *variable name* contained in the variable and look it up in the current scope. This is a variable name: ini_array This is not: ini_array['agis_core']['adapter'] I think you can use references here to do what you need. Warning: I only tested the basics of this in the interpreter without running this exact code. public function explode_ini() { $ini_array = array(); foreach($this->ini_array as $heading => $key_vals) { foreach ($key_vals as $k => $v) { $path = &$ini_array[$heading]; $subsection = explode('.', $k); foreach ($subsection as $ss) $path = &$path[$ss]; $path = $v; unset($path); } } $this->ini_array = $ini_array; } David
