JSON出力が1つだけ必要なため、これら3つのクエリを結合する方法を知りたいのですが、INNERJOINがこれを行うと思いました。しかし、これを使用する方法がわかりません。誰かが私を正しい道に導いてくれますか?
$json = array();
$following_string = mysqli_real_escape_string($mysqli,$_SESSION['id']);
$call="SELECT * FROM streamdata WHERE streamitem_id < '$lastID' AND streamitem_target=".$following_string." OR streamitem_creator=".$following_string." ORDER BY streamitem_id DESC LIMIT 10";
$chant = mysqli_query($mysqli, $call) or die(mysqli_error($mysqli));
$json['streamdata'] = array();
while ($resultArr = mysqli_fetch_assoc($chant)) {
$json['streamitem_id'] = $resultArr['streamitem_id'];
$json['streamitem_content'] = $resultArr['streamitem_content'];
$json['streamitem_timestamp'] = Agotime($resultArr['streamitem_timestamp']);
$json['streamdata'] = $json;
}
/***** COMMENTS *****/
$check = "SELECT comment_id, comment_datetime, comment_streamitem, comment_poster, comment_content FROM streamdata_comments WHERE comment_poster=".$following_string." ";
$check1 = mysqli_query($mysqli,$check);
$json['streamdata_comments'] = array();
while ($resultArr = mysqli_fetch_assoc($check1)) {
$json['comment_id'] = $resultArr['comment_id'];
$json['comment_content'] = $resultArr['comment_content'];

$json['comment_streamitem'] = $resultArr['comment_streamitem'];
$json['streamdata_comments'] = $json;
}
/***** USERS *****/
$check = "SELECT * FROM users WHERE id=".$following_string."";
