从一个会话变量这个数组 和mysql表字段是id、name、img等。如何加入array.product_id和table.id，

我的查询如$table=DB::select('SELECT * FROM products');我在 laravel 中以任何方式加入 mysql 表和数组？

Answer 1

您要加入的 mysql 转储丢失。但我想我明白你想要：

foreach($sessionArray as $sessionArrayKey => $sessionArrayVal)
{
    $findInDb = array_search($sessionArrayVal['product_id'], array_column($dbArray, 'id'));

    if ($findInDb)
    {
        $sessionArray[$sessionArrayKey] = array_merge($sessionArray[$sessionArrayKey],$dbArray[$findInDb])
    }

}
