json_decodeを使用します json_decodeドキュメント
また、必ず脱出してください！これが私が以下でそれをする方法です...
/* create a connection */
$mysqli = new mysqli("localhost", "root", null, "yourDatabase");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
/* let's say we're grabbing this from an HTTP GET or HTTP POST variable called jsonGiven... */
$jsonString = $_REQUEST['jsonGiven'];
/* but for the sake of an example let's just set the string here */
$jsonString = '{"name":"jack","school":"colorado state","city":"NJ","id":null}
';
/* use json_decode to create an array from json */
$jsonArray = json_decode($jsonString, true);
/* create a prepared statement */
if ($stmt = $mysqli->prepare('INSERT INTO test131 (name, school, city, id) VALUES (?,?,?,?)')) {
/* bind parameters for markers */
$stmt->bind_param("ssss", $jsonArray['name'], $jsonArray['school'], $jsonArray['city'], $jsonArray['id']);
/* execute query */
$stmt->execute();
/* close statement */
$stmt->close();
}
/* close connection */
$mysqli->close();
これがお役に立てば幸いです！
