array_merge & array_unique

Question

Is there an array function in PHP that somehow does array_merge, comparing the values, ignoring the keys? I think that array_unique(array_merge($a, $b

Answer 1

function umerge($arrays){
 $result = array();
 foreach($arrays as $array){
  $array = (array) $array;
  foreach($array as $value){
   if(array_search($value,$result)===false)$result[]=$value;
  }
 }
 return $result;
}
