Symfony2 Entity Array

Question

In my controller I have a function than set IP to entity:

$inventory = new Inventory();
$inventory->setIp($xml->COMPUTER->IP);

but $xml->COMPUTER->IP have two values. When I run:

foreach($xmlOcs->COMPUTER as $ips){
    echo $ips->IPADDRESS;
}

the two values are shown!

My question is, how can I set to entity ( $ip ) the two values?

My entity:

private $ipaddress = array(); 

public function setIpAddress($ipaddress) {
    $this->ipaddress = $ipaddress;

    return $this;
}

public function getIpAddress() {
    return $this->ipaddress;
}

Answer 1

Based on your example, this can easily be done if you use array empty key assignment :

foreach($xmlOcs->COMPUTER as $ips){
    $inventory->addIpAddress($ips->IPADDRESS);
}


private $ipaddress = array(); 

public function addIpAddress($ipaddress) {
    $this->ipaddress[] = $ipaddress;

    return $this;
}

public function getIpAddress() {
    return $this->ipaddress;
}

However this has nothing to do with Symfony, it is pure very basic php.
