）这里我想显示的数据只有价格大于15.0。如何在 Laravel

中使用foreach进行显示

`$产品列表的file_get_contents =（＆＃39; C：\ XAMPP \ htdocs中\ Laravel \资源\数据\ ProductList.json＆＃39）; $数据= json_decode（$产品列表，TRUE）;
//的print_r（$数据）;

    foreach($data as $key => $value) {
        if ($key == 'price' && $value > 15)
        echo $value;
    }
    print_r($value);

`

Answer 1

刀片文件中的

如果您的数组名称是$ data，那么您可以像这样使用foreach

@foreach($data as $key => $value)
    @if ($value['price'] > 15.0)
        echo $value['price'];
    @endif
@endforeach

在上面的代码中，我只是打印价格，但您可以在＆＃34; echo $ value [＆＃39;价格＆＃39;];＆＃34;

的地方编写代码

我希望它对你有所帮助

Answer 2

您可以使用array_filter（）函数。

$result = array_filter($input, function($value) {
    return $value['price'] > 15;
});

在上面的示例中，array_filter将循环遍历$ input数组，并且仅当price高于15时才将值添加到$ result数组。

我希望在laravel中显示价格大于15.0的那些值
