Php 数组中的数组中的数组-无法从JSON字符串获取数据

原职：

我提供的数据只有一行。我有许多相同的行，有不同的“Bestaende”和“Menge”：

您描述的

foreach

我理解，但它没有按预期工作

$jsonarray = json_decode($jsonfile,true);
echo 'Array 0 Menge: '.$jsonarray['0']['Bestaende']['0']['Menge'].'<br>'; 
echo 'Array 1 Menge: '.$jsonarray['1']['Bestaende']['0']['Menge'].'<br>'; 
echo 'Array 2 Menge: '.$jsonarray['2']['Bestaende']['0']['Menge'].'<br>'; 
echo 'Array 3 Menge: '.$jsonarray['3']['Bestaende']['0']['Menge'].'<br>'; 

好的。但是当我尝试

foreach

it时（因为我有一个基本数据列表），输出只有一行。我只得到一个条目“1”。没别的了

$x=0;
foreach($jsonarray[$x]['Bestaende'] as $idx => $Bestaende) {
   echo 'Print Menge: ';
   print_r($Bestaende['Menge']); 
 $x++;
}

所以我尝试在数组上循环以获取数据。结果是：

Array ( [Filiale] => 1 [FilialeBez] => Laden [Menge] => 1 [Gln] => [Dispo] => 0 )
Print Menge: 1

我对数组中的数组有问题。。。有没有更好的方法来获取我想要的数据

还是我的

foreach

循环出错了？

像这样尝试一下

foreach($jsonarray as $k=>$alldata) 
{
   foreach($alldata["Bestaende"] as $idx => $Bestaende) 
   {
       echo '<pre>';
       echo 'Print Menge: '.$Bestaende['Menge'];
       echo '</pre>';
   }
}

foreach（$jsonarray作为$k=>$alldata）
{
foreach（$alldata[“Bestaende”]作为$idx=>$Bestaende）
{
回声'；
回显“打印菜单：”.$Bestaende['Menge']；
回声'；
}
}

您只在只包含一项的

$jsonarray[0]['Bestaende']

上循环。您应该在

$jsonarray

上循环，然后从那里深入研究

Try this code..
$j = '[{"Ean":"","Barcode":"010241770148","Bezeichnung":"Richard 1516","Bestaende":[{"Filiale":1,"FilialeBez":"Laden","Menge":1,"Gln":null,"Dispo":0}],"Bestand":1,"Dispo":0,"Uvp":269.90,"Vk":269.90},      
 {"Ean":"","Barcode":"010241770149","Bezeichnung":"Richard 1516","Bestaende":[{"Filiale":1,"FilialeBez":"Laden","Menge":1,"Gln":null,"Dispo":0}],"Bestand":1,"Dispo":0,"Uvp":269.90,"Vk":269.90},
 {"Ean":"","Barcode":"010241770151","Bezeichnung":"Richard 1516","Bestaende":[{"Filiale":1,"FilialeBez":"Laden","Menge":1,"Gln":null,"Dispo":0}],"Bestand":1,"Dispo":0,"Uvp":269.90,"Vk":269.90},
 {"Ean":"","Barcode":"010241770152","Bezeichnung":"Richard 1516","Bestaende":[{"Filiale":1,"FilialeBez":"Laden","Menge":1,"Gln":null,"Dispo":0}],"Bestand":1,"Dispo":0,"Uvp":269.90,"Vk":269.90}]';

$a = json_decode($j,true);

foreach($a as $key => $value){
    if(!empty($value['Bestaende'])){
        foreach($value['Bestaende'] as $k=>$v){
             echo 'Print Menge: '.(!empty($v['Menge']) ? $v['Menge'] : '').'</br>';
        }
    }
}

试试这段代码。。
$j='[{“Ean”：““Barcode”：“010241770148”，“Bezeichung”：“Richard 1516”，“Bestaende”：[{“Filiale”：1，“FilialeBez”：“Ladden”，“Menge”：1，“Gln”：null，“Dispo”：0}]，“Bestand”：1，“Dispo”：0，“Uvp”：269.90，“Vk”：269.90}，

$a=json_解码（$j，true）；
foreach（$a作为$key=>$value）{
如果（！empty（$value['Bestaende']））{
foreach（$value['Bestaende']为$k=>$v）{
回显“Print Menge:”。（！empty（$v['Menge']）？$v['Menge']：“”）。
；
}
}
}

是的，您的foreach是错误的。

foreach($jsonarray as $k=>$alldata) 
{
   foreach($alldata["Bestaende"] as $idx => $Bestaende) 
   {
       echo '<pre>';
       echo 'Print Menge: '.$Bestaende['Menge'];
       echo '</pre>';
   }
}

foreach($jsonarray as $item) {
    echo 'Print Menge: ';
    print_r($item['Bestaende']['0']['Menge']); 
    // or even dive in deeper
    foreach ($item['Bestaende'] as $bestaende) {
        // .. $bestaende['Menge'];
    }
}

Try this code..
$j = '[{"Ean":"","Barcode":"010241770148","Bezeichnung":"Richard 1516","Bestaende":[{"Filiale":1,"FilialeBez":"Laden","Menge":1,"Gln":null,"Dispo":0}],"Bestand":1,"Dispo":0,"Uvp":269.90,"Vk":269.90},
