Question

我有以下函数从数据库中提取数据：

public function get_dataset() {
        $dataset = "";
        $data_set = $this->operations_model->get_date();
        foreach ($data_set as $value) {
            $dataset .= '["' . $value['date'] . '","' . $value['revenue'] . '"],';
        }

        echo $dataset;
    }

以下列格式返回数据：

["2015-10-13 15:53:20","15000.00"],["2015-10-13 15:53:20","5800.00"],["2015-10-13 15:53:20","5800.00"],["2015-10-13 15:53:20","5800.00"],["2015-10-13 15:54:56","15000.00"],

我想将上述数据格式化为以下格式：

[[2015-10-13 15:53:20,15000.00],[2015-10-13 15:53:20,5800.00],[2015-10-13 15:53:20,5800.00],[2015-10-13 15:53:20,5800.00],[2015-10-13 15:54:56,15000.00]]

Answer 1

试试这个

public function get_dataset() {
    $dataset = "[";
    $data_set = $this->operations_model->get_date();
    foreach ($data_set as $value) {
        $dataset .= '["' . $value['date'] . '","' . $value['revenue'] . '"],';
    }
    $dataset = substr($dataset, 0, -1);
    $dataset .= "]";

    echo $dataset;
}
