Dies ist der PHP-Code, den ich verwende, um die Elemente im Array zu drucken. Aber ich bekomme keine Ausgabe.

$ Antwort ist die Antwort, die ich von der API bekomme.

$array = json_decode($response, true); 
$test1 = $array['productAttributes']['title']; 
$test2 = $array['productInfoList']['productBaseInfo']['productIdentifier']['productId']; 

    echo $test1; 
    echo test2;

Debug Ihr Array sollte es sein '$ test1 = $ array [ 'productInfoList'] [0] [ 'productBaseInfo'] [ 'productAttributes'] [ 'title']; $ test2 = $ array ['productInfoList'] [0] ['productBaseInfo'] ['productIdentifier'] ['productId']; ' –

Sie sollten zuerst eine Schleife durch die Array-Werte (von json decodiert) und holen dann die benötigten Daten entsprechend, tun dies so etwas wie -

$array = json_decode($r, true); 
// print_r($array); //debug 
foreach($array['productInfoList'] as $product){ 
    echo $product['productBaseInfo']['productAttributes']['title']; 
    echo $product['productBaseInfo']['productIdentifier']['productId']; 
}

Schauen Sie genau auf die JSON, und Sie werden sehen, dass productInfoList ist ein Objekt mit einer Eigenschaft namens productBaseInfo, deren Wert ein Array von Objekten (zB [....] , obwohl es nur einen Eintrag hat), von denen jeder Eigenschaften wie productBaseInfo hat.

So ist die erste zu sehen (nur) Eintritt productBaseInfo.productIdentifier.productId, würden Sie wollen:

$test2 = $array['productInfoList'][0]['productBaseInfo']['productIdentifier']['productId']; 
// Note --------------------------^^^

Verwenden Sie den folgenden Code ein. Es gibt Ihnen Titel und ProductID $ array = json_decode ($ string, true);

$ test1 = $ array ['productInfoList'] [0] ['productBaseInfo'] ['productAttributes'] ['title']; $ test2 = $ array ['productInfoList'] [0] ['productBaseInfo'] ['productIdentifier'] ['productId'];

In JSON {bezeichnet und Object und [bezeichnet ein Array. Um alle Attribute können Sie so etwas wie folgt verwenden:

$array = json_decode($response, true); 
$productInfoList_Array = $array['productInfoList']; 
foreach($productInfoList_Array as $productInfoList){ 
    $productBaseInfo = $productInfoList['productBaseInfo']; 
    $productAttributes = $productBaseInfo['productAttributes']; 
    foreach($productAttributes as $Attribute_Key => $Attribute_Value){ 
     if (!is_array($Attribute_Value)){ 
      //Attribute Value is not an array. 
      echo "<b>{$Attribute_Key}</b>: {$Attribute_Value}"; 
      echo "<br>"; 
     }else{ 
      //Attribute Value is a sub array 
      foreach($Attribute_Value as $Attribute_Sub_Key => $Attribute_Sub_Value){ 
       echo "<b>Sub Key: {$Attribute_Sub_Key}</b>: {$Attribute_Sub_Value}"; 
       echo "<br>";     
      } 
     } 
    } 
    echo "<hr><b>End of Product.</b>"; 
}

Sehen Sie, dass productAttributes auch Subarray hat.

alle Apostroph entfernen. Versuchen Sie dies.

<?php 
    $array = json_decode($v, true); 
    <pre> 
    print_r($array['productInfoList'][0]['productBaseInfo']['productIdentifier']);  
print_r($array['productInfoList'][0]['productBaseInfo']['productAttributes']['title']); 
    ?>
