PHPのarray_key_existsはFALSE間違っ

Question

私のデータは、クライアントのCMSから引き出されている戻って、私は奇妙な結果出力

Array 
(
    [94] => stdClass Object 
     (
      [operation] => 0 
      [value] => 0 
     ) 

    [102] => stdClass Object 
     (
      [operation] => 501 
      [value] => 4 
     ) 

    [90] => stdClass Object 
     (
      [operation] => 0 
      [value] => 0 
     ) 
) 
94 
stdClass Object 
(
    [operation] => 0 
    [value] => 0 
) 
(boolean) FALSE 
(boolean) FALSE 
102 
stdClass Object 
(
    [operation] => 501 
    [value] => 4 
) 
(boolean) FALSE 
(boolean) FALSE 
90 
stdClass Object 
(
    [operation] => 0 
    [value] => 0 
) 
(boolean) FALSE 
(boolean) FALSE 

これを引き起こしているものの任意のアイデアを

print_r($appliance_data); 
foreach ($appliance_data as $adKey => $adValue) { 
    print_r($adKey); 
    print_r($adValue); 
    print_r(array_key_exists($adKey, $appliance_data)); 
    print_r(isset($appliance_data[$adKey])); 
} 

を取得していますか？

編集：エラーはarray_key_existsとisset は配列をループして得られたキーに対してFALSEを返します。

serialize($appliance_data) 



a:7:{s:2:"94";O:8:"stdClass":3:{s:9:"operation";s:3:"514";s:5:"value";s:1:"2";s:9:"frequency";s:1:"0";}s:3:"102";O:8:"stdClass":3:{s:9:"operation";s:3:"511";s:5:"value";s:1:"4";s:9:"frequency";s:1:"1";}s:2:"90";O:8:"stdClass":3:{s:9:"operation";s:1:"0";s:5:"value";s:1:"0";s:9:"frequency";s:1:"0";}s:2:"68";O:8:"stdClass":3:{s:9:"operation";s:3:"501";s:5:"value";s:1:"3";s:9:"frequency";s:1:"2";}s:2:"66";O:8:"stdClass":3:{s:9:"operation";s:1:"0";s:5:"value";s:1:"0";s:9:"frequency";s:1:"0";}s:2:"84";O:8:"stdClass":3:{s:9:"operation";s:1:"0";s:5:"value";s:1:"0";s:9:"frequency";s:1:"0";}s:2:"98";O:8:"stdClass":3:{s:9:"operation";s:1:"0";s:5:"value";s:1:"0";s:9:"frequency";s:1:"0";}} 

Answer 1

あなたは文字列 '94' の代わりに、int型94トライを使用している：

print_r(array_key_exists(94, $appliance_data)); 

編集：は私がすべてでローカルにこれを再現することはできません - することができます誰？

私は次のコードでこれを複製しようとした：

$first = new stdClass(); 
$first->operation = 0; 
$first->value = 0; 
$second = new stdClass(); 
$second->operation = 501; 
$second->value = 4; 
$third = new stdClass(); 
$third->operation = 0; 
$third->value = 0; 

$appliance_data = array(94 => $first, 102 => $second, 90 => $third); 
// Same output when using these lines too: 
// $appliance_data = array('94' => $first, '102' => $second, '90' => $third); 
// $appliance_data = array("94" => $first, "102" => $second, "90" => $third); 

print_r($appliance_data); 
echo "\n\n"; 
foreach ($appliance_data as $adKey => $adValue) { 
    print_r($adKey); 
    echo "\n"; 
    print_r($adValue); 
    print_r(array_key_exists($adKey, $appliance_data)); 
    echo "\n"; 
    print_r(isset($appliance_data[$adKey])); 
    echo "\n\n"; 
} 

そして、この出力ました：それはあるよう

Array 
(
    [94] => stdClass Object 
     (
      [operation] => 0 
      [value] => 0 
     ) 

    [102] => stdClass Object 
     (
      [operation] => 501 
      [value] => 4 
     ) 

    [90] => stdClass Object 
     (
      [operation] => 0 
      [value] => 0 
     ) 

)
