SQL结果中的PHP数组 [英] Php array from sql result

问题描述

如何从结果创建数组?我想在mysql IN()查询中使用数组.

How can i create an array from the result? I would like to use the array in a mysql IN() query.

//$array = array();
        $get_subscategoria = mysqli_query($kapcs, "SELECT kat_id FROM termek_kategoria WHERE kat_parent = '$id'");
        if(mysqli_num_rows($get_subscategoria) > 0 )
        {
            while($sub_kat = mysqli_fetch_array($get_subscategoria))
            {
                echo $sub_kat['kat_id'];
                //$array[] = $sub_kat;
            }
        }
        //print_r( $array );

现在，此代码将返回4行ID，可以正常工作.我想要一个具有这些ID的数组，例如1,2,3,4.

Now, this code gives back 4 row ID, that works okay. I would like an array with these ID-s, like 1,2,3,4.

推荐答案

while($sub_kat = mysqli_fetch_array($get_subscategoria))
{
$array[] = $sub_kat['kat_id'];
}
echo implode(",",$array);

它给出的结果是1,2,3,4

it give a result like 1,2,3,4
