Summe von spezifischem Element eines Mehrfacharrays

Question

Ich versuche, eine Summe in meinem variablen Sitzungskorb zu erhalten (es ist ein mehrfaches Array), ich möchte die Elemente zusammenfassen, die die Kosten des Produktes darstellen.

Page where I add elements into the basket 
 

 
<?php 
 

 
    session_start(); 
 

 
    include('link.php'); 
 

 
    
 

 

 

 
    if(!isset($_SESSION['basket'])){ 
 

 
    \t $_SESSION['basket']=[]; 
 

 
    } 
 

 
    // $id_permit=$_POST['id_fp']; 
 
    // $chosen_date=$_POST['date_permit']; 
 
    
 

 
    
 
    $_SESSION['little_basket']= array (
 

 
    'itemIdPermit'=> "'".$_POST["id_fp"]."'", 
 
    'itemChosenDate'=> "'".$_POST["date_permit"]."'", 
 
    'itemFinalPrice'=> "'".$_POST["final_price"]."'", 
 
    'itemFinalPriceNotDiscount'=>"'".$_POST["price_not_discount"]."'" 
 
                 ); 
 
            
 

 
    // $_SESSION['basket'][] = $_SESSION['little_basket']; 
 
    
 
    array_push($_SESSION['basket'], $_SESSION['little_basket']); 
 

 
    print_r($_SESSION['basket']); 
 

 
    // $_SESSION['basket']=[]; 
 

 
    // echo $_SESSION['basket']; 
 

 

 

 
    // header('location:index.php?area=fishing_permit'); 
 

 
    
 
    
 

 
?> 
 

 
Page where I show the contents of the basket 
 

 
<?php 
 

 
    // session_start(); 
 

 
    // include('link.php'); 
 
    // include('add_basket.php'); 
 

 
    // $ids = ''; 
 

 
    /* foreach($_SESSION['basket'] as $id){ 
 
    $ids = $ids . $id . ","; 
 
    };*/ 
 

 

 

 
    $lista_de_items_no_carrinho = $_SESSION['basket']; 
 

 

 

 

 

 
    
 

 
    ?> 
 
    <ul id="list_product"> 
 
     
 
    <?php 
 

 
    
 
    $basketLength=count($lista_de_items_no_carrinho); 
 

 

 

 
    for($i=0;$i< $basketLength;$i++){ 
 

 

 

 
    $sqlListChosenPermits = "select * from type_of_permits 
 
    where id_type_of_permit =".$lista_de_items_no_carrinho[$i]['itemIdPermit']; 
 

 
    $outcomeListChosenPermits = $link->query($sqlListChosenPermits); 
 

 
    $line = mysqli_fetch_assoc($outcomeListChosenPermits); 
 

 

 

 
    ?> 
 

 
    <li> 
 
     <div class="box_info"><h4><?php echo utf8_encode($line['type']); ?></h4><br>Validity:&nbsp;<?php echo utf8_encode($line['validity']);?>&nbsp;-&nbsp;Price:&nbsp;€<?php echo utf8_encode($line['price_eur']); ?> </div> 
 
     
 
      <div class="map">Map info</div> 
 
       <div class="rules">Rules</div> 
 
      
 
       <div class="permit_facsimile"><a href="<?php echo $line['map']; ?>">Permit facsimile</a></div> 
 
       <div class="chosen_date"><?php echo trim ($lista_de_items_no_carrinho[$i]['itemChosenDate'], "'") ;?></div> 
 
     <div class="price">Euro&nbsp;<?php 
 

 

 
     $var= trim ($lista_de_items_no_carrinho[$i]['itemFinalPrice'],"'"); 
 

 

 
     if (!empty($var)){ 
 
      
 
      echo ($var); 
 

 
     } else { 
 

 
      echo trim($lista_de_items_no_carrinho[$i]['itemFinalPriceNotDiscount'],"'"); 
 

 

 
      } ?></div> 
 
    
 
     <div class="add_basket"><a href="remove_from_basket.php?id=<?php echo $lista_de_items_no_carrinho[$i]['itemIdPermit']?>"><i class="fa fa-shopping-cart"></i>Remove from the Basket</a></div> 
 
     <input type="hidden" name="last_price" id="last_price" value="<?php 
 

 
    
 
     if (!empty($lista_de_items_no_carrinho[$i]['itemFinalPrice'])) { 
 
      
 
      echo trim ($lista_de_items_no_carrinho[$i]['itemFinalPrice'],"'"); 
 

 
     } else { 
 

 
      echo trim($lista_de_items_no_carrinho[$i]['itemFinalPriceNotDiscount'],"'"); 
 

 

 
      } ?>"> 
 

 
    </li> 
 

 
    <?php 
 

 
    } 
 

 

 
?> 
 

 

 
    
 
    </ul> 
 

 

 
<p>Total price:<span class="total_price"><?php 
 

 
$lista_de_items_no_carrinho = $_SESSION['basket']; 
 

 
$listaPrice=$lista_de_items_no_carrinho[$i]['itemFinalPriceNotDiscount']; 
 

 
$basketLength=count($listaPrice); 
 

 
$sum=0; 
 

 
for($k= 0; $k < $basketLength; $k++){ 
 

 
$sum += ($basketLength[$k]); 
 

 
echo ($sum); 
 

 
}?> 
 

 

 
</span></p> 
 

 

 
    
 

 
    <div class="buying"><button type="submit"><i class="fa fa-shopping-cart"></i>Conclude the purchase</button></div> 
 

 
    
 
</div>

würde Ich mag die Numerik Wert von 'ItemFinalPrice' zusammenzufassen und 'ItemFinalPriceNotDiscount'.

Vielen Dank im Voraus.

Answer 1

Sie einen Blick auf array_column und array_sum nehmen sollte:

$finalPriceSum = array_sum(array_column($basket, 'itemFinalPrice')); 
$finalPriceNoDiscountSum = array_sum(array_column($basket, 'itemFinalPriceNotDiscount'));
