php code to vb.net?

[diego.net]

Hi,

I want to post this to see if anyone can help me, I need to convert a php function into vb.net but I have no idea, here the function:

echo spin('{an {option|choice|right}|the basic} element');

function spin($s){
	preg_match('#\{(.+?)\}#is',$s,$m);
	if(empty($m)) return $s;
	
	$t = $m[1];
	
	if(strpos($t,'{')!==false){
		$t = substr($t, strrpos($t,'{') + 1);
	}
	
	$parts = explode("|", $t);
	$s = preg_replace("+\{".preg_quote($t)."\}+is", $parts[array_rand($parts)], $s, 1);
	
	return spin($s);
}

I don't mind to move the question to the projects(to paid you) if you know the answer.

Thanks,

Diego
