Answer 1

array_unique($array, SORT_REGULAR); 

Answer 2

Würde eine verschachtelte foreach verwenden wie folgt:

foreach ($aArray as $iPos => $aInnerArray) { 

    foreach ($aArray as $iPos => $aArrayToCheck) { 

     if($aInnerArray === $aArrayToCheck){ 

      unset($aArray($iPos)); 

     } 

    } 

}

//method for remove duplicate data 
function removeDuplicate($arr) { 
    //Define output 
    $outputs = []; 

    //Define temp for keep data 
    $tmps = []; 

    foreach ($arr as $each) { 
     //convert to string 
     $tmp = implode("|", $each); 

     if (!in_array($tmp, $tmps)) { 
      $tmps[] = $tmp; 
      $outputs[] = $each; 
     } 
    } 
    return $outputs;
