如何循环通过 PHP 代码将 JSON 数据插入 MySQL 数据库答案

【问题标题】：How to loop through PHP code to insert JSON data into MySQL database如何循环通过 PHP 代码将 JSON 数据插入 MySQL 数据库

【问题描述】：

这是我当前的 PHP 代码 - 这只引入一行数据，我需要它循环遍历动态和变化的 JSON - 它在不同时间可能是 5 行或 10 行。

我尝试了多种不同的方法来 foreach() 循环遍历数据，但都没有奏效。

$jsonCont = file_get_contents('nba.json');

$data = json_decode($jsonCont, true);

    $tip = $data['data'][0]['commence_time'];
    $teama = $data['data'][0]['teams'][0];
    $linea = $data['data'][0]['sites'][0]['odds']['spreads']['points'][0];
    $teamb = $data['data'][0]['teams'][1];
    $lineb = $data['data'][0]['sites'][0]['odds']['spreads']['points'][1];

$sql = "INSERT INTO nbagames(tip, teama, linea, teamb, lineb)
VALUES('$tip', '$teama', '$linea', '$teamb', '$lineb')";
if(!mysqli_query($conn,$sql))
{
    die('Error : ' . mysql_error());
}

我需要在这段代码中添加什么，以便它循环并抓取所有数据，而不仅仅是 1 行？

编辑：回复添加 JSON 数据 - 这是一个示例 - 我需要获取每场比赛 - 但我不需要多个站点（如果有超过 1 个站点有几率）

【解决方案1】：

你可以使用foreach：

$data = json_decode($jsonCont, true);

foreach($data['data'] as $line){
    $tip = $line['commence_time'];
    $teama = $line['teams'][0];
    $linea = $line['sites'][0]['odds']['spreads']['points'][0];
    $teamb = $line['teams'][1];
    $lineb = $line['sites'][0]['odds']['spreads']['points'][1];

    $sql = "INSERT INTO nbagames(tip, teama, linea, teamb, lineb)
    VALUES('$tip', '$teama', '$linea', '$teamb', '$lineb')";
    if(!mysqli_query($conn,$sql))
    {
        die('Error : ' . mysql_error());
    }
}

【讨论】：

这行得通。非常感谢。我正在使用 foreach($data as $data) - 我不完全理解 foreach($data['data'] as $line) 结构 - 我将自己做一些研究以更好地了解这一点。
您也可以在主 foreach 中循环站点。取决于你的数组结构。
