json - 如何删除 Json 响应中的双引号

Question

我的代码有这样的 Json 响应

["0","0","0","0","0","0","204.4"]

需要这样

[ 0, 0, 0, 0, 0, 0, 204.4 ]

为此我已经完成了codeigniter

$query = $this->db->query($selectQuery);
    $totalInvoice = array();
    foreach ($query->result() as $row)
    {
        $totalInvoice[] = $row->total;
    }
    print_r(json_encode($totalInvoice));

这个回应是

["0","0","0","0","0","0","204.4"]

Answer 1

在 json 中编码时添加 JSON_NUMERIC_CHECK（整数） 。

JSON_NUMERIC_CHECK (integer) : 将数字字符串编码为数字

$query = $this->db->query($selectQuery);
    $totalInvoice = array();
    foreach ($query->result() as $row)
    {
        $totalInvoice[] = $row->total;
    }
    print_r(json_encode($totalInvoice, JSON_NUMERIC_CHECK);
