Format data output using php

本文关键字：输出格式化数据 php 使用 | 更新日期: 2023-09-27

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;
    }

并以以下格式返回数据:

["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"],

我想把上面的数据格式化成以下格式:

[[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]]

try this

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;
}

try:

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