在MySQL中插入多个JSON列（使用API​​）

Question

I'm trying to store sports data json column using API but I can't get it working properly. Though I can insert the data but it insert only the first column result and keep it duplicating on all the later columns. At default, it shows 50 column upcoming football matches. My problem is only the first line result is duplicating..

Here is the code:

//connect to mysql db
$host = "localhost";
$user = "user";
$pass = "pass";
$db = "dname";
$conn = new mysqli($host, $user, $pass, $db) or die("ERROR:could not connect to 
    the database!!!");

//read the json file contents
$url = 'http://api.example.com/v1/events/upcoming?token=566645-
    sl1uDzY3tVvv9M&league_id=78&sport_id=1';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch) or die(curl_error($ch));

if ($data === false) {
    $info = curl_getinfo($ch);
    curl_close($ch);
    die('error occured during curl exec. Additioanl info: ' .
            var_export($info));
}
curl_close($ch);
$obj = json_decode($data, true);

foreach ($obj['results'] as $res) {
    $league = $res['league']['name'];
    $home = $res['home']['name'];
    $away = $res['away']['name'];
    $time = date("d/m h:i", $res['time']);
}
$sql = "INSERT INTO schedule(league, home, away, time)
    VALUES('$league', '$home', '$away', '$time')";
$result = mysqli_query($conn, $sql);
if (!$result) {
    die("ERROR :" . mysqli_error());
} else {
    echo "Records has been successfully inserted";
}
//close the connection
mysqli_close($conn);

The above code just insert the first json result, and it keeps repeating for the next column (result).. Help will be appreciated.

Answer 1

You are facing the problem because you are executing mysql query outside the foreach loop. You have to execute the query inside the loop.

Do something like

foreach ($obj['results'] as $res) 
{ 
$league = $res['league']['name']; 
$home = $res['home']['name']; 
$away = $res['away']['name']; 
$time = date("d/m h:i", 
$res['time']);

$sql = "INSERT INTO schedule(league, home, away, time) VALUES('$league', '$home', '$away', '$time')";
$result=mysqli_query($conn,$sql); 
if(!$result) 
{ 
die("ERROR :". mysqli_error()); 
} else 
{
echo "Records has been successfully inserted";
 } //close the connection mysqli_close($conn);
}

Answer 2

Your insert query must be in foreach like below:

foreach ($obj['results'] as $res){
    $league = $res['league']['name'];
    $home = $res['home']['name'];
    $away = $res['away']['name'];
    $time = date("d/m h:i", $res['time']);

    $sql = "INSERT INTO schedule(league, home, away, time)
    VALUES('$league', '$home', '$away', '$time')";
    $result=mysqli_query($conn,$sql);
    if(!$result){
        die("ERROR :". mysqli_error());
    }else{
        echo "Records has been successfully inserted";
    }
}

Though the above code can resolve your issue but its better if you start using MySqli Prepared Queries to make it more secure.

Put your insert query in foreach loop. Because your variable replace with new foreach result. Foreach reassign your veriables.

foreach ($obj['results'] as $res) {
    $league = $res['league']['name'];
    $home = $res['home']['name'];
    $away = $res['away']['name'];
    $time = date("d/m h:i", $res['time']);

    $sql = "INSERT INTO schedule(league, home, away, time)
    VALUES('$league', '$home', '$away', '$time')";
    $result = mysqli_query($conn, $sql);
    if (!$result) {
        die("ERROR :" . mysqli_error());
    } else {
        echo "Records has been successfully inserted";
    }
}
