Answer 1

You can use foreach and in_array to solve your issue as below.
$tempArray = $outArray = array();
$count = 1;
foreach($yourArray as $aKey=>$aVal){
if (in_array($aVal['splcode'], $aVal)){
//do something
continue; // it will skip the current loop if the condition satisfies
}
$outArray[$count] = $aVal;
$tempArray[] = $aVal['splcode'];
$count++;
}
//You will get the result in the variable $outArray
unset($tempArray); // clear the temp array

Answer 2

The array_unique function will do this for you. You just needed to add the SORT_REGULAR flag:
$items_thread = array_unique($items_thread, SORT_REGULAR);
