use Doctrine\ORM\Mapping as ORM;

class Job

    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="title", type="string", length=100, nullable=false)
     */
    private $title;

    /**
     * @var string
     *
     * @ORM\Column(name="description", type="text")
     */
    private $description;

    /**

    private $location;

尝试从每个阵列获得“totalprice”。

Array ( [0] => Array ( [totalprice] => 671 [total] => 0 [price_per_p] => 2 ) [1] => Array ( [totalprice] => 312 [total] => 0 [price_per_p] => 2 ) )

但这根本不起作用。

$i = 0;
foreach($arr as $x_values => $x) {
   echo $x[$i]["totalprice"];
   $i++;
}

我想首先从数组1获取“循环”，然后在第二个“循环”获取数组2

只需删除$ i索引即可。不需要$ i变量。
