PHPでSQLite3 #3データ取得(SELECT)
$tableName="access";
$sql="SELECT id,name,cnt FROM $tableName WHERE name='{$name}' ORDER BY cnt ASC";
$result=$db->query($sql);
$tmp=[];
while ($row = $result->fetchArray(SQLITE3_ASSOC)) {
	$tmp[]=$row;
}
echo json_encode($tmp);
$db->close();

データ重複しないように取得
$sql="SELECT DISTINCT name FROM $tableName";
$result=$db->query($sql);
if($result===FALSE){
	$db->close();
	echo $message;
	exit;
}
$tmp=[];
while ($row = $result->fetchArray(SQLITE3_ASSOC)) {
	$value=$row['name'];
	$tmp[]=$value;
}
echo json_encode($tmp);
