为什么无法从list.php显示json数据？

Question

index.php 为什么无法从list.php显示json数据？

我希望list.php中的数据出现在表的index.php中。

我想解析list.php上的json数据。但发生错误：

<?php 
	require_once('connection.php');

	$query = mysqli_query($conn, 
		"SELECT * FROM transaksi ORDER BY transaksi_id DESC"
		);
	
	$result = array();
	while($row = mysqli_fetch_array($query)){
		array_push($result,array(
			'transaksi_id'	=> $row['transaksi_id'],
			'status'		=> $row['status'],
			'jumlah'		=> $row['jumlah'],
			'keterangan'	=> $row['keterangan'],
			'tanggal'		=> date("d/m/Y", strtotime($row['tanggal'])),
			'tanggal2'		=> $row['tanggal']
		));
	}


	$query = mysqli_query($conn, 
		"SELECT (SELECT COUNT(transaksi_id) AS counts FROM transaksi) AS total_transaksi, (SELECT SUM(jumlah) FROM transaksi WHERE status='MASUK') AS masuk, (SELECT SUM(jumlah) FROM transaksi WHERE status='KELUAR') AS keluar"
		);

	while ($row = mysqli_fetch_assoc($query)) { 
			
			$total	= $row['total_transaksi'];
			$masuk 	= $row['masuk'];
			$keluar	= $row['keluar'];

		}
	
	
	echo json_encode(array(
		'total'		=> $total,
		'masuk'		=> $masuk 	== null ? 0 : $masuk,
		'keluar'	=> $keluar 	== null ? 0 : $keluar,
		'saldo'		=> ($masuk - $keluar),
		'result'	=> $result
		), JSON_NUMERIC_CHECK);

	mysqli_close($conn);
