如何遍歷PHP代碼以將JSON數據插入MySQL數據庫

Question

這是我當前的PHP代碼-僅導入一行數據，我需要它遍歷動態變化的JSON-在不同時間可能是5行或10行。

我嘗試了多種不同的方法來foreach（）遍歷數據，但沒有一種有效。

$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());
}

我需要在此代碼中添加些什么，以便它遍歷並獲取所有數據而不僅僅是一行？

編輯：回復添加JSON數據-這是一個示例-我需要獲取所有游戲-但我不需要多個站點（如果有多個站點，則賠率較高）

Answer 1

您可以使用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());
    }
}
