Some code lumps

Pretty print for arrays / structs:
function pp($arr){
	$retStr = '';
	if (is_array($arr)){
		foreach ($arr as $key=>$val){
		    if (is_array($val)){
			$retStr .= '' . $key . ' => ' . pp($val) . '';
		    }else{
			$retStr .= '' . $key . ' => ' .  $val .  '';
	}}}
	$retStr .= '';
	return $retStr;
}
