优化此PHP代码的提示

Question

Below is the code which I'm willing to compress:

$somefield = 0;
if ($config->get('var1.one') && is_numeric($config->get('var1.one'))) {
  $somefield = $this->entityManager->getStorage('node')->load($config->get('var1.one'));
}
$different_field = 0;
if ($config->get('var2.two') && is_numeric($config->get('var2.two'))) {
  $different_field = $this->entityManager->getStorage('node')->load($config->get('var2.two'));
}

Answer 1

After your comment, what I think you want is something like:

$somefield = checkVar("var1.one");
$different_field = checkVar("var2.two");

function checkVar($name) {
  if ($config->get($name) && is_numeric($config->get($name))) {
    return $this->entityManager->getStorage('node')->load($config->get($name));
  } else {
    return 0;
  }
}

I think this what you wanted. The names I used are not necessarily the best ones, you should use some better suited to the actual use of the function.
