pushing values from one array to another

[jowatkins]

OK, I have two arrays, one populated from a query, $listarray, and the other passed to the function from another script, $additionaloptions.

What I want to do is move through the $additionaloptions array, and if the item doesn't match any item in the $list array, push that item onto the $list array.

Does this make sense?

I've tried the following, but it keeps crashing.

if (!empty($additionaloptions)) 
{
  foreach ($additionaloptions as $extra)
  {
    foreach ($listarray as $dbitem)
    {
       if ($extra == $dbitem)
       {
          continue;
       }
       else
       {
          array_push ($listarray, $extra);
       }
    }
  }
}

Try this:

if (!empty($additionaloptions))
{
foreach ($additionaloptions as $extra)
{
if(!in_array($extra,$listarray))
{
array_push ($listarray, $extra);
}

}
}
