我正在研究一种方法，从mySQL数据库中提取数据，并将文本显示为数组，但我有它，因此只有一个数据字符串可用，每个实例都用逗号分隔。1,2,3,4有没有一种方法可以让它在每个逗号后打断或开始一行，而不是像这样出现一团混乱：
1 package KRAFT Deluxe Macaroni & Cheese Dinner Sharp Cheddar Cheese Sauce, 1 lb Ground Beef, 1 Jar Spaghetti Sauce, 1/2 Cup KRAFT Shredded Mozzarella Cheese
代码：
<?php
require_once '../scripts/app_config.php';
require_once '../../scripts/authorize.php';
require_once '../scripts/database_connection.php';
// Get the user ID of the user to show
$User_id = $_REQUEST['User_id'];
// Gets User Id
$select_query = "SELECT * FROM users WHERE User_id = " . $User_id;
// Run the query to get User Name
$result1 = mysql_query($select_query);
if ($result1) {
$row = mysql_fetch_array($result1);
$first_name = $row['First_name'];
$last_name = $row['Last_name'];
$email = $row['Email'];
$User_id = $row['User_id'];
} else {
handle_error("There was a problem finding your " .
"information in our system.",
"Error locating user with ID {$User_id}");
}
$Recipe_Id = $_REQUEST['Id'];
$result = mysql_query( "SELECT * FROM recipes WHERE Id = " . $Recipe_Id )
or die(mysql_error());
while($row = mysql_fetch_array($result))
{
$Id = $row['Id'];
$Name = $row['Name'];
$Ingredients = $row['Ingredients'];
$Category1 = $row['Category1'];
$Category2 = $row['Category2'];
$Directions = $row['Directions'];
$Creator = $row['User_Name'];

如果我做对了，你只需要这样的东西：
echo "<p>" . str_replace(', ',', <br />',$row['Ingredients']) . "</p>";
