此问题已经在这里有了答案：
我正在尝试从数据库检索数据并将其显示在表中，但是我不知道如何在php中实现它。另外，我还需要一些帮助，以根据customer_id和date对显示的数据实施搜索功能。
<?php
include 'connect.php';
$query = ("SELECT * FROM 'transaction'");
$result = mysqli_query($conn, $query);
?>
<!DOCTYPE html>
<html lang="en">
<body>
<form class="form-inline my-2 my-lg-0" action="search2.php" method="POST">
<input class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit" name="search">Search</button>
</form>
</div>
</nav>
<!-- Table -->
<h1>Sales</h1>
<div class="table-responsive">
<table class="table table-striped table-sm">
<thead>
<tr>
<th>Customer ID</th>
<th>Date</th>
<th>Outlet</th>
<th>Employee ID</th>
<th>Product ID</th>
<th>Quantity</th>
</tr>
</thead>
<tbody>
<?php while ($row = mysqli_fetch_row($result)) :?>
<tr>
<th scope="row"><?php echo $i; ?></th>
<td><?php echo $row['customer_id']; ?></td>
<td><?php echo $row['date']; ?></td>
<td><?php echo $row['outlet_id']; ?></td>
<td><?php echo $row['emp_id']; ?></td>
<td><?php echo $row['Prod_id']; ?></td>
<td><?php echo $row['quantity']; ?></td>
</tr>
<?php
if (!$result) {
die ("Database access failed: " .mysql_error());
}
endwhile; ?>
</tbody>
</table>
</div>
</body>
</html>
这是DB连接的单独文件。
<?php
$ser = "localhost";
$user = "root";
$pass = "";
$db = "music_store_db";
// Create connection
$conn = new mysqli($ser, $user, $pass, $db);
// Check connection
if (mysqli_connect_error()){
die("Connection Failed: ".mysqli_connect_error());
}
// echo "Connection Success";
?>
单击此页面的链接时，它应该显示来自数据库的销售交易。
我得到的输出是：
警告：mysqli_fetch_row（）期望参数1为mysqli_result，给定布尔值
请使用由mysqli_fetch_row插入的mysqli_fetch_assoc并从查询中的表名之前和之后删除

include 'connect.php';
$query = ("SELECT * FROM transaction");
