我有一个函数在php中需要显示表内的所有记录。但是我似乎不能在HTML中显示它们。
下面是我的php代码:<?php
function display_products(){
$query = mysql_query("Select id, naam,prijs from product");
$data = array();
while ($row = mysql_fetch_assoc($result)){
array_push($data, $row);
}
return $data;
}?>
这是我试图在html中显示的数组:
<?php
$products = display_products();
foreach ($products as $product): ?>
<ul>
<li><?php echo $product['naam'] ?></li>
<li><?php echo $product['prijs'] ?></li>
</ul>
}
<?php endforeach; unset($product); ?>
尝试如下操作(不要忘记更改mysqli_connect()函数中的常量)。此外，如果您熟悉这个，请尝试使用PDO。
<?php
function display_products() {
//Connect to database
$connection = mysqli_connect(SERVER, USER, MY_PASSWORD, MY_DATABASE);
mysqli_set_charset($connection, 'utf8');
if (!$connection) {
die("Database connection failed: " . mysqli_error());
}
//Make the query
$query = "SELECT id, naam, prijs FROM product;";
$result = mysqli_query($connection, $query);
$data = array();
//Fetch all the data
while ($row = mysqli_fetch_array($result)) {
array_push($data, $row);
}
return $data;
}
?>
<?php
$products = display_products();
foreach ($products as $product): ?>
<ul>
<li><?php echo $product['naam']; ?></li>
<li><?php echo $product['prijs']; ?></li>
</ul>
<?php endforeach; ?>
