Jungs ich ein Array haben, und ich habe Probleme beim Drucken nur die Nachricht, weil ich „Invalid argument für foreach geliefert()“ Ich weiß nicht, warum.

Hier ist mein foreach-Code:

foreach ($userNode as $array1 => $array2) { 
    echo "array1: $array1 <br>"; 
    foreach ($array2 as $array3 => $array4) { 
     echo "array3: $array3 <br>"; 
     foreach ($array4 as $array5 => $array6) { 
      echo "array5: $array5 <br>"; 
      foreach ($array6 as $array7 => $array8) { 
       if ($array7=="message") { 
        echo "$array7 : " . "$array8 <br>"; 
       } 
      } 
     } 
    } 
} 

Answer 1

Nicht sicher, warum Sie so oft wiederholen müssen. Ich würde es so machen:

foreach($arr['feed']['data'] as $data){ 
    print_r($data['message']); 
} 

Answer 2

if (is_array($userNode) || is_object($userNode)) { 
foreach ($userNode as $array1 => $array2) { 
    echo "array1: $array1 <br>"; 
    if (is_array($array2) || is_object($array2)) { 
     foreach ($array2 as $array3 => $array4) { 
      echo "array3: $array3 <br>"; 
      if (is_array($array4) || is_object($array4)) { 
       foreach ($array4 as $array5 => $array6) { 
        echo "array5: $array5 <br>"; 
        if (is_array($array6) || is_object($array6)) { 
         foreach ($array6 as $array7 => $array8) { 
          if ($array7=="message") { 
           echo "$array7 : " . "$array8 <br>"; 
          } 
         } 
        } 
       } 
      } 
     } 
    } 
}}
