我有功能
private function updateCharacters($oApiKeyInfo) // argument is base entity
{
$aXmlCharacter = $this->fXml->getXmlRowset($this->oXml, 'row');
// insert new
foreach ($aXmlCharacter as $oXmlCharacter)
{
$loopData = $this->fXml->getXmlAttributesAsArray($oXmlCharacter);
$oApiKeyInfoCharacters = new apiKeyInfoCharacters();
$oApiKeyInfoCharacters
->setKeyID($this->keyID)
->setCharacterID($loopData['characterID'])
->setCharacterName($loopData['characterName'])
->setCorporationID($loopData['corporationID'])
->setCorporationName($loopData['corporationName'])
->set_apiKeyInfo_byKeyID($oApiKeyInfo);
$this->em->persist($oApiKeyInfoCharacters);
}
// $this->em->flush() is in main (public) function
}
但是,它会创建重复项......我希望在 db 中只有 $aXmlCharacter (数组)中的条目,其他条目必须被删除
现在上面的代码只是添加新条目,但我需要删除以前的
有人可以帮忙处理吗?并请展示工作示例
