Class, echo array from method on return

[spighita]

Hi
I need to print the array using echo $variable[0] instead of print_r

<?php
class lan {
function mon(){
$phone="1-800-300-5421";
return explode("-",$phone);


}//mon

function sec(){
	return $this->mon();
}
}//lan

$we=new lan;
print_r($we->sec());


?>

thanks for anyone who helps

Got it,

$ed=$we->sec();
echo $ed[2];
